25-623: The Tuscan archipelago (chain of islands) is located between the Ligurian Sea (north) and Tyrrhenian Sea (south), in the Mediterranean Sea . The Italian national park protects 56,776 hectares (140,300 acres) of sea and 17,887 hectares (44,200 acres) of island (land) habitats . The Arcipelago Toscano National Park includes the seven main islands ( isola ) of the Tuscan Archipelago: The highest point in

50-458: A palm tree, which, upon completion in 2006, would add 56 km (35 miles) to the coastline. The island is designed to be a city within itself, featuring shopping centers, restaurants, hotels, and residential properties. Palm Jumeirah was built entirely from sand and rocks; no concrete or steel was used to build the island. This was done following the order of the Ruler of Dubai , who came up with

75-576: Is a chain, cluster, or collection of islands , or sometimes a sea containing a small number of scattered islands. Archipelagos are sometimes defined by political boundaries. For example, while they are geopolitically divided, the San Juan Islands and Gulf Islands geologically form part of a larger Gulf Archipelago. The word archipelago is derived from the Ancient Greek ἄρχι-( arkhi- , "chief") and πέλαγος ( pélagos , "sea") through

100-476: Is an artificial archipelago that features a palm tree that is 50% larger than the original Palm Jumeirah. The island has a larger crescent shape. Space has been created between the crescent and the tree to build boardwalks that encircle the "fronds" of the "palm" and spell out an Arabic poem written by Sheikh Mohammed bin Rashid Al Maktoum . Construction on the island began in 2001, but progression

125-531: Is damaging the marine habitat, burying coral reefs, oyster beds and subterranean fields of seagrass, threatening local marine species and other species dependent on them for food. Oyster beds have been covered in as much as two inches of sediment, while above the water, beaches are eroding with the disruption of natural currents In 2006, the World Wildlife Fund announced, "[The] UAE's human pressure on global ecosystems (its ecological footprint ) [is]

150-526: Is the site of numerous private residences and hotels. From the air, the archipelago resembles a stylized palm tree within a circle. Construction began in 2001 and was financed mainly by Dubai's income from petroleum. By 2009, 28 hotels had opened on the site. The Atlantis is the largest hotel currently constructed on Palm Jumeirah. The island has a population of over 18,000 people as of 2015. Palm Jebel Ali ( Google 25°00′N 54°59′E  /  25.000°N 54.983°E  / 25.000; 54.983 )

175-775: The Italian arcipelago . In antiquity , "Archipelago" (from Medieval Greek * ἀρχιπέλαγος and Latin archipelagus ) was the proper name for the Aegean Sea . Later, usage shifted to refer to the Aegean Islands (since the sea has a large number of islands). Archipelagos may be found isolated in large amounts of water or neighbouring a large land mass. For example, Scotland has more than 700 islands surrounding its mainland, which form an archipelago. Archipelagos are often volcanic, forming along island arcs generated by subduction zones or hotspots , but may also be

200-511: The Jumeirah (Dubai) coastline. Additional data was collected with technological improvements, including remote video monitoring of Dubai beaches, sediment sampling and analysis, near-shore directional wave and current recordings, and intensive measurement exercises at selected locations using Acoustic Doppler Current Profiler (ADCP) equipment. Because of this, they can constantly monitor the continuously changing environmental conditions along

225-410: The breakwaters. To achieve this, small structural modifications were made to the breakwaters surrounding the island, allowing the seawater to move through the breakers without causing any damage to the island. To prevent erosion of the sand from the island, maintenance systems spray material along the coast of the island and also along the coast of Dubai. A vibro-compaction technique was used to prevent

250-555: The coast of Dubai , United Arab Emirates . The Palm Islands were constructed around the same time as The World Islands . Nakheel Properties is the Palm Islands real estate developer. The creation of the islands began in 2001 and ended around 2006/2007. These islands have significantly impacted ocean sediment and wildlife in the surrounding area. Palm Jumeirah ( Google 25°07′00″N 55°08′00″E  /  25.11667°N 55.13333°E  / 25.11667; 55.13333 )

275-524: The coast of Dubai. Instead of hitting the shores directly, the waves move unusually around the new obstruction. This has led to the weakening of the shores of Dubai. To properly manage their shorelines and effects, Dubai relies on its coastal monitoring program. Established in 1997, the Dubai Coastal Monitoring program began studying the baseline bathymetric (measurement of the depth of water in oceans or seas) and topographic survey of

300-400: The construction process with the help of deep-sea divers. The divers checked the alignment and placement of the rocks beneath the surface to ensure their stability. The shape of the island was monitored using the global positioning system. The sand on top of the island was sprayed by a technique called rainbowing . The whole island was planned to have no stagnant water between the island and

325-472: The environmental damage stems from disturbed sediment from the construction of the Palm Island. The sediment decreased the amount of sunlight filtering down to the sea vegetation and injured the surrounding marine fauna. Environmental disturbances caused by changes in sediment and coastal erosion have attracted the attention of environmental groups such as Greenpeace , who criticized the Palm Islands for

350-442: The highest in the world. The country is supposedly at present five times more unsustainable than any other country" (Samarai, 2007). It also mentioned that the construction from the start-up to date had caused many visible ecological and environmental changes that threatened the future. According to a study published in the journal Water in 2022, the construction of Palm Jumeirah Island has increased water-soluble materials, changed

375-427: The idea for Palm Islands and the design. Installation of utilities and pipelines was complicated and required a lot of labour. To counteract the waves and constant motion of the sea, breakwaters were built around the island. They are 3 meters high and 160 km in total length. Expanded over a length of about 11.5 km, the base of these breakwaters and the island itself were constantly monitored during

400-483: The lack of sustainability. The non-profit environmental news service Mongabay has reported on Dubai's artificial islands, stating that: Significant changes in the maritime environment [of Dubai] [... ] As a result of the dredging and redepositing of sand for the construction of the islands, the typically crystalline waters of the Persian Gulf at Dubai have become severely clouded with silt. Construction activity

425-572: The park is Mount Capanne ( Italian : Monte Capanne ), at 1,019 metres (3,343 ft) in elevation, on the island of Elba. This Italian location article is a stub .

Archipelago An archipelago ( / ˌ ɑːr k ə ˈ p ɛ l ə ɡ oʊ / AR -kə- PEL -ə-goh ), sometimes called an island group or island chain ,

450-423: The process of liquefaction. This was done to hold the island's base together and to make a strong foundation for further construction. The construction of the Palm Islands along the coast of Dubai has had a significant impact on the surrounding environment, resulting in changes to area wildlife (especially aquatic life), coastal erosion , alongshore sediment transport, and wave patterns. The origin of most of

475-465: The result of erosion , deposition , and land elevation . Depending on their geological origin, islands forming archipelagos can be referred to as oceanic islands , continental fragments , or continental islands . Oceanic islands are mainly of volcanic origin, and widely separated from any adjacent continent. The Hawaiian Islands and Galapagos Islands in the Pacific , and Mascarene Islands in

500-670: The shelf. The islands of the Inside Passage off the coast of British Columbia and the Canadian Arctic Archipelago are examples. Artificial archipelagos have been created in various countries for different purposes. Palm Islands and The World Islands off Dubai were or are being created for leisure and tourism purposes. Marker Wadden in the Netherlands is being built as a conservation area for birds and other wildlife. The largest archipelago in

525-432: The south Indian Ocean are examples. Continental fragments correspond to land masses that have separated from a continental mass due to tectonic displacement. The Farallon Islands off the coast of California are an example. Sets of islands formed close to the coast of a continent are considered continental archipelagos when they form part of the same continental shelf, when those islands are above-water extensions of

550-563: The water's spectral profile, and increased the water surface temperature around the island. Variations in alongshore sediment transport have resulted in changes in erosion patterns along the UAE coast, which has also been exacerbated by altered wave patterns as the waters of the Persian Gulf attempt to move around the new obstruction of the islands. The rock walls constructed around the palm islands can result in different wave patterns along

575-499: The world by number of islands is the Archipelago Sea , which is part of Finland . There are approximately 40,000 islands, mostly uninhabited. The largest archipelagic state in the world by area, and by population, is Indonesia . Palm Islands The Palm Islands consist of three artificial archipelagos : Palm Jumeirah , Dubai Islands (formerly known as Palm Deira or Deira Islands), and Palm Jebel Ali , on

600-557: Was halted due to the Great Recession . The Deira Islands ( 25°20′00″N 55°16′05″E  /  25.3333°N 55.2681°E  / 25.3333; 55.2681 ) are four undeveloped artificial islands off the coast of Deira, Dubai , United Arab Emirates . As of 2021, little development has occurred on the islands. At first, the project—which was supposed to be a part of the Palm Islands—was known as Palm Deira. It

625-558: Was intended to be the biggest palm of the three, roughly eight times as big as the Palm Jumeirah. Dubai built the Palm Tree Islands to increase the coastline for tourists. Dubai is known for its sunny weather and beaches, but more than 72 km (45 miles) of coastline was needed to accommodate the goal of tripling the number of tourists to 15 million annually. The solution was to construct a massive island shaped like
