100-545: Smithsonian scientists first came to Panama during the construction of the Panama Canal from 1904 to 1914. The Secretary of the Smithsonian Institution , Charles Doolittle Walcott , reached an agreement with Federico Boyd to conduct a biological inventory of the new Canal Zone in 1910, and this survey was subsequently extended to include all of Panama. Thanks largely to their efforts, the governor of

200-795: A canal across the isthmus, with some favoring a canal across Nicaragua and others advocating the purchase of the French interests in Panama. Bunau-Varilla , who was seeking American involvement, asked for $ 100 million, but accepted $ 40 million in the face of the Nicaraguan option. In June 1902, the US Senate voted in favor of the Spooner Act , to pursue the Panamanian option, provided the necessary rights could be obtained. On 22 January 1903,

300-715: A canal. Numerous canals were built in other countries in the late 18th and early 19th centuries. The success of the Erie Canal through central New York in the United States in the 1820s and the collapse of the Spanish Empire in Latin America resulted in growing American interest in building an inter-oceanic canal. Beginning in 1826, US officials began negotiations with Gran Colombia (present-day Colombia, Venezuela, Ecuador, and Panama), hoping to gain

400-531: A century of research in a protected setting, Barro Colorado Island has become a major global center for tropical research. Barro Colorado is open for public day visits, but advance reservations must be made. Although STRI is based in Panama, research is conducted throughout the tropics. The Smithsonian's Forest Global Earth Observatory (ForestGEO) network (formerly CTFS, Center for Tropical Forest Science ) uses standard study protocols to monitor more than 70 forest plots in 28 countries across Africa, Asia, Europe and

500-533: A concession to build a canal. Jealous of their newly gained independence and fearing domination by the more powerful United States, president Simón Bolívar and New Granada officials declined American offers. After the collapse of Gran Colombia, New Granada remained unstable under constant government intrigue. Great Britain attempted to develop a canal in 1843. According to the New-York Daily Tribune , 24 August 1843, Barings Bank of London and

600-866: A female scientist at the STRI by a male scientist. This was detailed in a December 9th 2020 letter to the White House Gender Policy Council (GPC) , written by Laura Dunn, a victim's rights attorney and the legal representative for the victims. The STRI receives federal funding, awarded from a committee on which the US Vice President sits, which was the reason for the letter. From an article in Nature : "Tewksbury says that all bedrooms now have lockable doors, but he notes that such safeguards are impractical in field sites, where researchers sleep in tents." Another measure that has been taken

700-766: A global survey of levels of genetic isolation in coral reef organisms. STRI is headquartered at the Earl S. Tupper Research, Library and Conference Center in Ancón , Panama City . STRI has other installations around Panama City including the Center for Tropical Paleoecology and Archaeology, a Canopy Access Crane system in the Parque Natural Metropolitano (with a sister crane in the San Lorenzo National Park on Panama's Caribbean slope), and

800-579: A high worker mortality rate . The US took over the project in 1904 and opened the canal in 1914. The US continued to control the canal and surrounding Panama Canal Zone until the Torrijos–Carter Treaties provided for its handover to Panama in 1977. After a period of joint American–Panamanian control, the Panamanian government took control in 1999. It is now managed and operated by the Panamanian government-owned Panama Canal Authority . The original locks are 33.5 meters (110 ft) wide and allow

900-625: A reservoir for the canal. The layout of the canal as seen by a ship passing from the Atlantic to the Pacific is: Thus, the total length of the canal is 80 km (50 mi). In 2017 it took ships an average of 11.38 hours to pass between the canal's two outer locks.

1000-622: A sea-level canal (like the Suez), but he visited the site only a few times, during the dry season which lasts only four months of the year. His men were unprepared for the rainy season, during which the Chagres River , where the canal started, became a raging torrent, rising up to 10 m (33 ft). The dense jungle was alive with venomous snakes, insects, and spiders, but the worst challenges were yellow fever , malaria , and other tropical diseases, which killed thousands of workers; by 1884,

1100-593: A sea-level canal, as had been attempted by the French and temporarily abandoned by them in 1887 for a ten locks system designed by Philippe Bunau-Varilla, and definitively in 1898 for a lock-and-lake canal designed by the Comité Technique of the Compagnie Nouvelle de Canal de Panama as conceptualized by Adolphe Godin de Lépinay in 1879. But in 1906 Stevens, who had seen the Chagres in full flood,

1200-715: A self-educated engineer who had built the Great Northern Railroad . Stevens was not a member of the ICC; he increasingly viewed its bureaucracy as a serious hindrance, bypassing the commission and sending requests and demands directly to the Roosevelt administration in Washington, DC. One of Stevens' first achievements in Panama was in building and rebuilding the housing, cafeterias, hotels, water systems, repair shops, warehouses, and other infrastructure needed by

1300-600: A settlement began and resulted in the Torrijos–Carter Treaties . On 7 September 1977, the treaty was signed by President of the United States Jimmy Carter and Omar Torrijos , de facto leader of Panama. This mobilized the process of granting the Panamanians free control of the canal so long as Panama signed a treaty guaranteeing the permanent neutrality of the canal. The treaty led to full Panamanian control effective at noon on 31 December 1999, and

1400-663: A small field station is on the island of Coibita in Coiba National Park. The station provides access to the 500-km Coiba Island and extensive coral reef systems of the Eastern Tropical Pacific. An article released by Buzzfeed News in 2021 told the story of 16 women who experienced "a pattern of sexual misconduct by high-ranking men at the institute, one of whom acknowledged his inappropriate behavior". Incidents included verbal harassments, physical sexual assault, unwanted attention, and have resulted in

1500-594: A treaty, in the name of the Société civile internationale du Canal interocéanique par l'isthme du Darien headed by general Étienne Türr, with the Colombian government, known as the Wyse concession, to build an interoceanic canal through Panama. The first attempt to construct a canal through what was then Colombia's province of Panama began on 1 January 1881. The project was inspired by the diplomat Ferdinand de Lesseps , who

1600-641: Is also a parish ( parroquia ) of the District of Panama, located in the Panama Canal adjacent area. The area where the district of Ancón is located was always conceived as a place of transit. From the Spanish arrival on the Isthmus of Panama in 1501, it was thought to build there a road between the Atlantic and Pacific oceans, an idea that was materialized with the construction of the Panama Canal. During

1700-672: Is an artificial 82-kilometer (51-mile) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean , cutting across the Isthmus of Panama , and is a conduit for maritime trade. Locks at each end lift ships up to Gatun Lake , an artificial fresh water lake 26 meters (85 ft) above sea level , created by damming up the Chagres River and Lake Alajuela to reduce the amount of excavation work required for

1800-508: Is by changing the way that fellowship positions are awarded in the Institute to avoid the extremely unbalanced power dynamics that can occur. In an article by Nature : "Tewksbury says that, in an attempt to blunt at least some of the power of staff scientists, the STRI is changing how junior researchers are awarded fellowships. In the past, staff scientists would discuss among themselves which researchers might be worthy of fellowships and match

1900-570: Is home to the Marcos A. Gelabert International Airport, the Grand National Transportation Terminal, and Albrook Mall, the largest mall in the country. The district of Ancón includes the Parque Natural Metropolitano, a vast jungle located a few minutes from the city, and its highest elevation, Ancon Hill . In its urban areas, you can visit several historical sites of the Panamanian capital, the building that houses

2000-402: Is sometimes misinterpreted as the "99-year lease" because of misleading wording included in article 22 of the agreement. Almost immediately, the treaty was condemned by many Panamanians as an infringement on their country's new national sovereignty. This would later become a contentious diplomatic issue among Colombia, Panama, and the United States. President Roosevelt famously stated, "I took

2200-546: The Culebra Cut , valued at about $ 1.00 per cubic yard. The United States also paid the new country of Panama $ 10 million and a $ 250,000 payment each following year. In 1921, Colombia and the United States entered into the Thomson–Urrutia Treaty , in which the United States agreed to pay Colombia $ 25 million: $ 5 million upon ratification, and four $ 5 million annual payments, and grant Colombia special privileges in

2300-760: The Hay–Herrán Treaty was signed by United States Secretary of State John M. Hay and Colombian Chargé Tomás Herrán . For $ 10 million and an annual payment, it would have granted the United States a renewable lease in perpetuity from Colombia on the land proposed for the canal. The treaty was ratified by the US Senate on 14 March 1903, but the Senate of Colombia unanimously rejected the treaty since it had become significantly unpopular in Bogotá due to concerns over insufficient compensation, threat to sovereignty, and perpetuity. Roosevelt changed tactics, based in part on

2400-617: The Illinois Central Railroad , as chief engineer of the Panama Canal Project. Overwhelmed by the disease-plagued country and forced to use often dilapidated French infrastructure and equipment, as well as being frustrated by the overly bureaucratic ICC, Wallace resigned abruptly in June 1905. The ICC brought on a new chairman, Theodore P. Shonts , and a new chief engineer was appointed, John Frank Stevens ,

2500-589: The Mallarino–Bidlack Treaty of 1846, and actively supported the separation of Panama from Colombia . Shortly after recognizing Panama, he signed a treaty with the new Panamanian government under terms similar to the Hay–Herrán Treaty. On 2 November 1903, US warships blocked sea lanes against possible Colombian troop movements en route to put down the Panama rebellion. Panama declared independence on 3 November 1903. The United States quickly recognized

2600-591: The Mallarino–Bidlack Treaty , negotiated between the US and New Granada, granted the United States transit rights and the right to intervene militarily in the isthmus. In 1848, the discovery of gold in California , on the West Coast of the United States, generated renewed interest in a canal crossing between the Atlantic and Pacific oceans. William Henry Aspinwall , who had won the federal subsidy to build and operate

2700-497: The Panama Canal during its construction. As part of the construction effort, the historic Gorgas Army Hospital was founded and built on the hillside. The first ship to officially transit the canal, SS  Ancon , was named after the district. The community continued to serve as housing for employees of the Panama Canal Company until 1980, when parts of it began to be turned over to the Panamanian government under

2800-546: The Panama Canal Authority (ACP) assumed command of the waterway. The Panama Canal remains one of the chief revenue sources for Panama. Before this handover, the government of Panama held an international bid to negotiate a 25-year contract for operation of the container shipping ports located at the canal's Atlantic and Pacific outlets. The contract was not affiliated with the ACP or Panama Canal operations and

2900-530: The Republic of New Granada entered into a contract for the construction of a canal across the Isthmus of Darien (Isthmus of Panama). They referred to it as the Atlantic and Pacific Canal, and it was a wholly British endeavor. Projected for completion in five years, the plan was never carried out. At nearly the same time, other ideas were floated, including a canal (and/or a railroad) across Mexico's Isthmus of Tehuantepec . That did not develop, either. In 1846,

3000-486: The cargo ship SS  Ancon . The opening of the Panama Canal in 1914 caused a severe drop in traffic along Chilean ports due to shifts in maritime trade routes, despite the closure of the canal for nearly seven months after a landslide in the Culebra Cut on 18 September 1915. The burgeoning sheep farming business in southern Patagonia suffered a significant setback by the change in trade routes, as did

3100-432: The 16 km² Barro Colorado Island , which is covered with tropical forest and boasts a nearly intact mammal fauna. It also includes 40 km² of surrounding mainland peninsulas covered by forests in various stages of succession, serving as a site for manipulative field experiments. The monument adjoins Panama's 220 km² Soberania National Park . With an unparalleled store of background information reflecting almost

3200-732: The 1977 Torrijos-Carter Treaties . Modern-day Ancón is a corregimiento (the Panamanian equivalent of a suburb in the United States) of Panama City, serving mainly as a residential area. The Gorgas Army Hospital building is now the Panamanian Oncology Hospital, primarily used for cancer research. The area also houses Panama's Supreme Court, just a few feet away from the Gorgas Army Hospital building, and several Smithsonian Tropical Research Institute buildings for research into tropical biology. Ancón

3300-792: The 30 million cu yd (23 million m ) excavated by the French. As quickly as possible, the Americans replaced or upgraded the old, unusable French equipment with new construction equipment that was designed for a much larger and faster scale of work. 102 large, railroad-mounted steam shovels were purchased, 77 from Bucyrus-Erie , and 25 from the Marion Power Shovel Company . These were joined by enormous steam-powered cranes, giant hydraulic rock crushers , concrete mixers , dredges , and pneumatic power drills, nearly all of which were manufactured by new, extensive machine-building technology developed and built in

In 1668, the English physician and philosopher Sir Thomas Browne speculated in his encyclopedic work, Pseudodoxia Epidemica , that "some Isthmus have been eaten through by the Sea, and others cut by the spade: And if the policy would permit, that of Panama in America were most worthy

3500-424: The Americas. The protocols were developed on BCI in the early 1980s. More than six million individual trees representing 12,000 species are being studied. STRI's Biological Diversity of Forest Fragments project created experimental forest fragments of 0.01, 0.1, and 1.0 km² to study the consequences of landscape transformation on forest integrity in the central Amazon region. STRI marine scientists are conducting

3600-694: The Canal Zone declared Barro Colorado Island (BCI) a biological reserve in 1923, making it one of the earliest biological reserves in the Americas. During the 1920s and 1930s BCI, in Gatun Lake , became an outdoor laboratory for scientists from U.S. universities and the Smithsonian Institution. By 1940, when BCI was designated the Canal Zone Biological Area (CZBA), more than 300 scientific publications had described

3700-478: The Canal Zone. In return, Colombia recognized Panama as an independent nation. The US formally took control of the canal property on 4 May 1904, inheriting from the French a depleted workforce and a vast jumble of buildings, infrastructure, and equipment, much of it in poor condition. A US government commission, the Isthmian Canal Commission (ICC), was established to oversee construction; it

3800-492: The Chagres River above Gatun Lake. Completed in 1935, the dam created Madden Lake (later Alajuela Lake), which provides additional water storage for the canal. In 1939, construction began on a further major improvement: a new set of locks large enough to carry the larger warships that the United States was building at the time and planned to continue building. The work proceeded for several years, and significant excavation

3900-600: The Colombians being unable to put down the Panamanian rebellion and expel the United States troops occupying what today is the independent nation of Panama. On 6 November 1903, Philippe Bunau-Varilla, as Panama's ambassador to the United States, signed the Hay–Bunau-Varilla Treaty , granting rights to the United States to build and indefinitely administer the Panama Canal Zone and its defenses. This

4000-489: The French manager of the New Panama Canal Company, eventually managed to persuade Lesseps that a lock-and-lake canal was more realistic than a sea-level canal. The Comité Technique, a high level technical committee, was formed by the Compagnie Nouvelle to review the studies and work—that already finished and that still ongoing—and come up with the best plan for completing the canal. The committee arrived on

4100-659: The Isthmus in February 1896 and went immediately, quietly and efficiently about their work of devising the best possible canal plan, which they presented on 16 November 1898. Many aspects of the plan were similar in principle to the canal that was finally built by the Americans in 1914. It was a lock canal with two high level lakes to lift ships up and over the Continental Divide. Double locks would be 738 feet long and about 30 feet deep (225 m × 9 m); one chamber of each pair would be 82 feet (25 m) wide,

4200-407: The Isthmus, started the canal and then left Congress not to debate the canal, but to debate me." Several parties in the United States called this an act of war on Colombia: The New York Times described the support given by the United States to Bunau-Varilla as an "act of sordid conquest". The New York Evening Post called it a "vulgar and mercenary venture". The US maneuvers are often cited as

4300-675: The Naos Marine and Molecular Laboratories on the Amador Causeway. The marine laboratory has a dock, wet lab and scientific diving office, facilitating research in the Gulf of Panama. The causeway, which is at the Pacific entrance to the Panama Canal, is also home to STRI's visitor center, the Punta Culebra Nature Center, which is open year-round to the general public and school groups. STRI has laboratories in

4400-515: The Pacific mail steamships at around the same time, benefited from the gold discovery. Aspinwall's route included steamship legs from New York City to Panama, and from Panama to California, with an overland portage through Panama. This route with an overland leg in Panama was soon frequently traveled, as it provided one of the fastest connections between San Francisco, California, and the East Coast cities, about 40 days' transit in total. Nearly all

Still, in formal nautical communications, the simplified directions "southbound" and "northbound" are used. The canal consists of artificial lakes , several improved and artificial channels, and three sets of locks . An additional artificial lake, Alajuela Lake (known during the American era as Madden Lake), acts as

4600-419: The Panama Railway) to cross the isthmus; it opened in 1855. This overland link became a vital piece of Western Hemisphere infrastructure, greatly facilitating trade. The later canal route was constructed parallel to it, as it had helped clear dense forests. An all-water route between the oceans was still the goal. In 1855, William Kennish , a Manx -born engineer working for the United States government, surveyed

4700-426: The Republic of Panama was formalized in the Panama Canal Treaties of 1977, which gradually transferred control of the Canal Zone to Panama. The treaties created the Barro Colorado Nature Monument, which included BCI and five surrounding peninsulas, and granted STRI custody of the monument. Panama granted STRI International Mission status in 1985 and, in 1997, the nation extended STRI's custodianship of facilities beyond

4800-400: The US army troops that were supporting the Panamanian rebels. The reason an army of conscripts was sent was that it was the best response the Colombians could muster, as Colombia still was recovering from a civil war between Liberals and Conservatives from October 1899, to November 1902, known as the " Thousand Days War ". The US was fully aware of these conditions and even incorporated them into

4900-483: The United States to hand over the canal to Panama increased after the Suez Crisis in 1956, when the United States used financial and diplomatic pressure to force France and the UK to abandon their attempt to retake control of the Suez Canal , previously nationalized by the Nasser regime in Egypt. Panamanian unrest culminated in riots on Martyr's Day , 9 January 1964, when about 20 Panamanians and 3–5 US soldiers were killed. A decade later, in 1974, negotiations toward

In many places, the new Gatun Lake flooded over the original rail line, and a new line had to be constructed above Gatun Lake's waterline. Between 1912 and 1914 there was a controversy about the tolls for the canal . In 1907, Stevens resigned as chief engineer. His replacement, appointed by President Theodore Roosevelt,

5100-457: The attempt: it being but few miles over, and would open a shorter cut unto the East Indies and China". Given the strategic location of Panama, and the potential of its narrow isthmus separating two great oceans, other trade links in the area were attempted over the years. One early example of this was ill-fated Darien scheme , launched by the Kingdom of Scotland in 1698 to set up an overland trade route. Generally inhospitable conditions thwarted

With the establishment of STRI, permanent staff scientists were hired and fellowship programs were initiated to support aspiring tropical biologists. The first director after the name change was Martin Humphrey Moynihan . A strong relationship with

5300-420: The buildings belonging to former US military bases are today sites of Panamanian governmental and nongovernmental institutions, such as the City of Knowledge , the main science and technology park in the country, in the area of the former Fort Clayton. Besides its importance in the fields of trade and intermodal transportation, the district is becoming increasingly relevant in terms of services and tourism. Ancón

5400-404: The canal was completed in 1914, 401 years after Panama was first crossed overland by the Europeans in Vasco Núñez de Balboa 's party of conquistadores . The United States spent almost $ 500 million (roughly equivalent to $ 15.2 billion in 2023) to finish the project. This was by far the largest American engineering project to date. The canal was formally opened on 15 August 1914, with the passage of

5500-401: The canal. In 2017, it took ships an average of 11.38 hours to pass between the canal's two outer locks. The American Society of Civil Engineers has ranked the Panama Canal one of the Seven Wonders of the Modern World . The earliest record regarding a canal across the Isthmus of Panama was in 1534, when Charles V , Holy Roman Emperor and King of Spain, ordered a survey for a route through

5600-406: The canal. Locks then lower the ships at the other end. An average of 200,000,000 L (52,000,000 US gal) of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts. The Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous route around

5700-489: The classic example of US gunboat diplomacy in Latin America, and the best illustration of what Roosevelt meant by the old African adage, "Speak softly and carry a big stick [and] you will go far." After the revolution in 1903, the Republic of Panama became a US protectorate until 1939. In 1904, the United States purchased the French equipment and excavations, including the Panama Railroad , for US$ 40 million, of which $ 30 million related to excavations completed, primarily in

A call for locks on doors where researchers slept occurred after the assault of

5900-470: The construction of tunnels and locks. A second Isthmian exploratory visit began on 6 December 1877, where two routes were explored in Panama, the San Blas route and a route from Bahía Limón to Panama City, the current Canal route. The French had achieved success in building the Suez Canal in the Middle East. While it was a lengthy project, they were encouraged to plan for a canal to cross the Panamanian isthmus. Wyse went to Bogotá and on 20 March 1878, signed

In 1914, steam shovels from the Panama Canal were purchased and put to use in Chuquicamata copper mine of northern Chile. By the 1930s, water supply became an issue for the canal, prompting construction of the Madden Dam across

They said that this would be a less treacherous route for ships than going around the southern tip of South America, and that tropical ocean currents would naturally widen the canal after construction. During an expedition from 1788 to 1793, Alessandro Malaspina outlined plans for construction of

While these conscripts may have been able to defeat the Panamanian rebels, they would not have been able to defeat

7300-524: The other 59 ft (18 m). There would be eight sets of locks, two at Bohio Soldado and two at Obispo on the Atlantic side; one at Paraiso, two at Pedro Miguel, and one at Miraflores on the Pacific. Artificial lakes would be formed by damming the Chagres River at Bohio and Alhajuela, providing both flood control and electric power. At this time, US President Theodore Roosevelt and the United States Senate were interested in establishing

7400-493: The passage of Panamax ships. A third, wider lane of locks was constructed between September 2007 and May 2016. The expanded waterway began commercial operation on 26 June 2016. The new locks allow transit of larger, Neopanamax ships. Annual traffic has risen from about 1,000 ships in 1914, when the canal opened, to 14,702 vessels in 2008, for a total of 333.7 million Panama Canal/Universal Measurement System (PC/UMS) tons . By 2012, more than 815,000 vessels had passed through

7500-493: The planning of the Panama intervention as the US acted as an arbitrator between the two sides. The peace treaty that ended the "Thousand Days War" was signed on the USS Wisconsin on 21 November 1902. While in port, the US also brought engineering teams to Panama with the peace delegation to begin planning the canal's construction before the US had even gained the rights to build the canal. All these factors would result in

7600-567: The project. After two years of extensive work, the mosquito-spread diseases were nearly eliminated . Despite the monumental effort, about 5,600 workers died from disease and accidents during the US construction phase of the canal. Besides healthier and far better living conditions for the workers, another benefit given to American citizens working on the Canal was a medal for two years of service. Additional bars were added for each two-year period after that. Designed by Victor D. Brenner and featuring

7700-455: The railway, which was to prove crucial in transporting millions of tons of soil from the cut through the mountains to the dam across the Chagres River. Colonel William C. Gorgas had been appointed chief sanitation officer of the canal construction project in 1904. Gorgas implemented a range of measures to minimize the spread of deadly diseases, particularly yellow fever and malaria , which had recently been shown to be mosquito-borne following

7800-413: The rainy climate. In France, Lesseps kept the investment and supply of workers flowing long after it was obvious that the targets were not being met, but eventually the money ran out. The French effort went bankrupt in 1889 after reportedly spending US$ 287,000,000; an estimated 22,000 men died from disease and accidents, and the savings of 800,000 investors were lost. Work was suspended on May 15, and in

7900-493: The researchers' life on Barro Colorado Island .

8000-506: The slopes to minimize landslides into the canal. Steam shovels were used in the construction of the canal, purchased from Bay City Industrial Works, a business owned by William L. Clements in Bay City, Michigan . Bucket chain excavators manufactured by both Alphonse Couvreux and Wehyer & Richemond and Buette were also used. Other mechanical and electrical equipment was limited in capabilities, and steel equipment rusted rapidly in

8100-680: The southernmost tip of South America via the Drake Passage , the Strait of Magellan or the Beagle Channel . It is one of the largest and most difficult engineering projects ever undertaken. Colombia , France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and

8200-406: The then-current president they were popularly known as The Roosevelt Medal. A total of 7189 were ultimately issued, with a few people receiving as many as four bars. Certificates are available today. In 1905, a US engineering panel was commissioned to review the canal design, which had not been finalized. In January 1906 the panel, in a majority of eight to five, recommended to President Roosevelt

8300-492: The thousands of incoming workers. Stevens began the recruitment effort to entice thousands of workers from the United States and other areas to come to the Canal Zone to work. Workers from the Caribbean—called " Afro-Panamanians "—came in large numbers and many settled permanently. Stevens tried to provide accommodation in which the workers could work and live in reasonable safety and comfort. He also re-established and enlarged

8400-508: The town of Gamboa, which is abutted by Soberanía National Park, the Panama Canal and the Chagres River in central Panama. The Gamboa labs facilitate research on forest ecology, animal behavior, plant physiology, evolution and other disciplines. Adjacent to Soberanía, STRI has the 700-hectare Panama Canal Watershed Experiment, which studies multiple land-use practices to determine their impact on hydrology, carbon storage and potential for reforestation. STRI has two Caribbean marine laboratories. One

8500-602: The water from the lake. Gatun Lake would connect to the Pacific through the mountains at the Gaillard (Culebra) Cut. Unlike Godin de Lépinay with the Congrès International d'Etudes du Canal Interocéanique, Stevens successfully convinced Roosevelt of the necessity and feasibility of this alternative scheme. The construction of a canal with locks required the excavation of more than 17 million cu yd (13 million m ) of material over and above

8600-497: The widespread call for changes within the Institute. The fallout has included the firing of employees, an internal investigation, individuals being stripped of their titles, and institutional resources being made available. However, many victims still face retaliation from the accused, including the withholding of data. Josh Tewksbury, who was appointed director of STRI in July 2021, says of the STRI's measures to safeguard employees since

8700-496: The work of Cuban epidemiologist, Carlos Finlay and American pathologist, Walter Reed . Investment was made in extensive sanitation projects, including city water systems, fumigation of buildings, spraying of insect-breeding areas with oil and larvicide, installation of mosquito netting and window screens, and elimination of stagnant water. Despite opposition from the commission (one member said his ideas were barmy), Gorgas persisted, and when Stevens arrived, he threw his weight behind

8800-489: The years when the Panama Canal was under the control of the United States, many administrative facilities, military bases, and communities were built in the adjacent areas, forming part of the former Panama Canal Zone . When these areas were reverted to Panama under the Torrijos-Carter Treaties, several alternatives were proposed to integrate the district to the city of Panama. The current district of Ancón

8900-469: Was 11,518; its population as of 2000 was 11,169. It is sometimes considered a suburb or small town within Panama City, northeast of the limits of the town of Balboa . Ancon Hill is also the name of a large hill that overlooks Panama City and once served as a form of protection from pirates and sea invasion. The township was originally located around this hill, and was created to house employees of

9000-462: Was US Army Major George Washington Goethals of the US Army Corps of Engineers . Soon to be promoted to lieutenant colonel and later to general, he was a strong, West Point -trained leader and civil engineer with experience in canals (unlike Stevens). Goethals directed the work in Panama to a successful conclusion in 1914, two years ahead of the target date of 10 June 1916. Goethals divided

9100-602: Was able to raise considerable funds in France as a result of the huge profits generated by his successful construction of the Suez Canal . Although the Panama Canal needed to be only 40 percent as long as the Suez Canal, it was much more of an engineering challenge because of the combination of tropical rain forests, debilitating climate, the need for canal locks, and the lack of any ancient route to follow. Lesseps wanted

9200-499: Was carried out on the new approach channels, but the project was canceled after World War II. After World War II, US control of the canal and the Canal Zone surrounding it became contentious; relations between Panama and the United States became increasingly tense. Many Panamanians felt that the Zone rightfully belonged to Panama; student protests were met by the fencing-in of the zone and an increased military presence there. Demands for

9300-610: Was created to take over the project. A minimal workforce of a few thousand people was employed primarily to comply with the terms of the Colombian Panama Canal concession, to run the Panama Railroad , and to maintain the existing excavation and equipment in salable condition. The company sought a buyer for these assets, with an asking price of US$ 109,000,000. In the meantime, they continued with enough activity to maintain their franchise. Phillipe Bunau-Varilla ,

9400-469: Was created when a new political-administrative division for the reverted areas was adopted, by Act No. 18 of August 29, 1979, and later amended by Law No. 1 of October 27, 1982. The areas located in the Pacific sector became part of this district, while those located on the Atlantic side were incorporated into the district of Cristobal, in the province of Colon. They remain characterized by a strong US urban architectural style. Due to its geographical location,

9500-412: Was given control of the Panama Canal Zone, over which the United States exercised sovereignty. The commission reported directly to Secretary of War William Howard Taft and was directed to avoid the inefficiency and corruption that had plagued the French 15 years earlier. On 6 May 1904, President Theodore Roosevelt appointed John Findley Wallace , formerly chief engineer and finally general manager of

9600-1389: Was published as an anthology in 1982, The Ecology of a Tropical Rainforest . STRI has an average of 350 ongoing research projects and publishes more than 400 peer-reviewed articles in scientific journals every year. STRI's research facilities allow staff scientists, fellows and visiting scientists to achieve their research objectives. Most of STRI's staff scientists reside in the tropics and are encouraged to pursue their own research priorities without geographic limitations. The continuity of their long-term programs enables in-depth investigations that attract an elite group of fellows and visitors. Active support for fellows and visitors leverages resources further and attracts more than 1,200 scientists to STRI each year. STRI hosts 10-15 university field courses every year. Participating universities include Princeton, McGill, Northeastern, Wisconsin Green Bay, Yale, Harvard, Ohio State, Arizona State, Marquette, Texas A&M Butler, Cambridge, Dartmouth College and University of Vermont. STRI also runs an intensive field course for Panamanian and Central American undergraduates. Since 1965, STRI has supported some 5,500 fellows and interns of various academic levels, from undergraduate, master and PhD students, to postdoctoral and senior researchers. The Barro Colorado Nature Monument includes

9700-594: Was similarly responsible for the Pacific 3-mile (4.8 km) breakwater in Panama Bay , the approach channel to the locks, and the Miraflores and Pedro Miguel locks and their associated dams and reservoirs. The Central Division, under Major David du Bose Gaillard of the United States Army Corps of Engineers , was assigned one of the most difficult parts: excavating the Culebra Cut through

9800-501: Was summoned to Washington; he declared a sea-level approach to be "an entirely untenable proposition". He argued in favor of a canal using a lock system to raise and lower ships from a large reservoir 85 ft (26 m) above sea level. This would create both the largest dam (Gatun Dam) and the largest human-made lake (Gatun Lake) in the world at that time. The water to refill the locks would be taken from Gatun Lake by opening and closing enormous gates and valves and letting gravity propel

9900-415: Was the first self-propelled vessel to transit the canal from ocean to ocean. This vessel crossed the canal from the Atlantic in stages during construction, finally reaching the Pacific on 7 January 1914. SS Cristobal (a cargo and passenger ship built by Maryland Steel , and launched in 1902 as SS Tremont ) on 3 August 1914, was the first ship to transit the canal from ocean to ocean. The construction of

10000-498: Was won by the firm Hutchison Whampoa , a Hong Kong–based shipping interest owned by Li Ka-shing . While globally the Atlantic Ocean is east of the isthmus and the Pacific is west, the general direction of the canal passage from the Atlantic to the Pacific is from northwest to southeast, because of the shape of the isthmus at the point the canal occupies.
