1204-636: A service of the Department of the Navy . This arrangement has a broad historical basis, as the Coast Guard has been involved in wars as diverse as the War of 1812 , the Mexican–American War , and the American Civil War , in which the cutter Harriet Lane fired the first naval shots attempting to relieve besieged Fort Sumter . The last time the Coast Guard operated as a whole within the Navy

1290-466: A small fraction of total lake areas. Because the littoral zone is important for many recreational and industrial purposes, it is often severely affected by many human activities that increase nutrient loading, spread invasive species, cause acidification and climate change , and produce increased fluctuations in water level.

1720-527: Is managed and used by the Coast Guard for tracking pollution and safety incidents in the nation's ports. The National Maritime Center (NMC) is the merchant mariner credentialing authority for the USCG under the auspices of the Department of Homeland Security . To ensure a safe, secure, and environmentally sound marine transportation system, the mission of the NMC is to issue credentials to fully qualified mariners in

1806-457: Is often attracted to shorelines, and settlement often disrupts breeding habitats for littoral zone species. For example, many turtles are killed on roads when they leave the water to lay their eggs in upland sites. Fish can be negatively affected by docks and retaining walls which remove breeding habitat in shallow water. Some shoreline communities even deliberately try to remove wetlands since they may interfere with activities like swimming. Overall,

Their designations, district office and area of responsibility are as follows: Shore establishment commands exist to support and facilitate

1978-497: Is particularly dependent upon past water levels; in general, the area of wet meadows along lakes and rivers increases with natural water level fluctuations. Many of the animals in lakes and rivers are dependent upon the wetlands of littoral zones, since the rooted plants provide habitat and food. Hence, a large and productive littoral zone is considered an important characteristic of a healthy lake or river. Littoral zones are at particular risk for two reasons. First, human settlement

2064-554: Is the oldest continuously operating naval service of the United States. As Secretary of the Treasury, Hamilton headed the Revenue-Marine, whose original purpose was collecting customs duties at U.S. seaports. By the 1860s, the service was known as the U.S. Revenue Cutter Service and the term Revenue-Marine gradually fell into disuse. The modern U.S. Coast Guard was formed by a merger of the U.S. Revenue Cutter Service and

The term has no single definition. What is regarded as the full extent of the littoral zone, and the way the littoral zone is divided into subregions, varies in different contexts. For lakes, the littoral zone is the nearshore habitat where photosynthetically active radiation penetrates to

2408-539: The Minnesota Department of Natural Resources defines littoral as that portion of the lake that is less than 15 feet in depth. Such fixed-depth definitions often do not accurately represent the true ecological zonation, but are sometimes used because they are simple measurements to make bathymetric maps or when there are no measurements of light penetration. The littoral zone comprises an estimated 78% of Earth's total lake area. The littoral zone may form

2752-475: The pelagic zone often rely heavily on resources from the littoral zone. Littoral areas of ponds and lakes are typically better oxygenated, structurally more complex, and afford more abundant and diverse food resources than do profundal sediments. All these factors lead to a high diversity of insects and very complex trophic interactions. The great lakes of the world represent a global heritage of surface freshwater and aquatic biodiversity. Species lists for 14 of

In addition to gathering and distributing spill/incident information for Federal On Scene Coordinators and serving as

6450-794: The shore establishment commands. The military college for the USCG is called the United States Coast Guard Academy which trains both new officers through a four year program and enlisted personnel joining the ranks of officers through a 17 week program called Officer Candidate School (OCS). Abbreviated TRACEN, the other Training Centers include Training Center Cape May for enlisted bootcamp, Training Center Petaluma and Training Center Yorktown for enlisted "A" schools and "C" schools, and Coast Guard Aviation Technical Training Center and Coast Guard Aviation Training Center Mobile for aviation enlisted "A" school, "C" schools, and pilot officer training. The Coast Guard has

6536-431: The specific program and the background of the individual, the course is three, four or five weeks long. The first week of the five-week course is an indoctrination week. The DCO program is designed to commission officers with highly specialized professional training or certain kinds of previous military experience. Littoral zone The word littoral may be used both as a noun and as an adjective . It derives from

6622-466: The spring low tide line, which is rarely not inundated. It is alternately exposed and submerged once or twice daily. Organisms living here must be able to withstand the varying conditions of temperature, light, and salinity. Despite this, productivity is high in this zone. The wave action and turbulence of recurring tides shape and reform cliffs, gaps and caves, offering a huge range of habitats for sedentary organisms. Protected rocky shorelines usually show

6708-404: The sublittoral zone refers to coastal regions with significant tidal flows and energy dissipation, including non-linear flows, internal waves , river outflows and oceanic fronts. In practice, this typically extends to the edge of the continental shelf , with depths around 200 meters. In marine biology, the sublittoral zone refers to the areas where sunlight reaches the ocean floor, that is, where

6794-444: The sublittoral zone. Within the sublittoral, marine biologists also identify the following: Shallower regions of the sublittoral zone, extending not far from the shore, are sometimes referred to as the subtidal zone . Many vertebrates (e.g., mammals, waterfowl, reptiles) and invertebrates (insects, etc.) use both the littoral zone as well as the terrestrial ecosystem for food and habitat. Biota that are commonly assumed to reside in

6880-403: The top of this area, patches of dark lichens can appear as crusts on rocks. Some types of periwinkles , Neritidae and detritus feeding Isopoda commonly inhabit the lower supralittoral. The eulittoral zone (also called the midlittoral or mediolittoral zone ) is the intertidal zone , known also as the foreshore . It extends from the spring high tide line, which is rarely inundated, to

6966-585: The water is never so deep as to take it out of the photic zone . This results in high primary production and makes the sublittoral zone the location of the majority of sea life. As in physical oceanography, this zone typically extends to the edge of the continental shelf . The benthic zone in the sublittoral is much more stable than in the intertidal zone; temperature, water pressure, and the amount of sunlight remain fairly constant. Sublittoral corals do not have to deal with as much change as intertidal corals. Corals can live in both zones, but they are more common in

7052-416: The world's largest lakes reveal that 15% of the global diversity (the total number of species) of freshwater fishes, 9% of non-insect freshwater invertebrate diversity, and 2% of aquatic insect diversity live in this handful of lakes. The vast majority (more than 93%) of species inhabit the shallow, nearshore littoral zone, and 72% are completely restricted to the littoral zone, even though littoral habitats are

7138-497: The world, rivaling the capabilities and size of most navies . The U.S. Coast Guard is a humanitarian and security service. It protects the United States ' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across U.S. territorial waters and its Exclusive Economic Zone . Due to ever-expanding risk imposed by transnational threats through

7224-421: The world. The U.S. Coast Guard operates under the U.S. Department of Homeland Security during peacetime. During times of war, it can be transferred in whole or in part to the U.S. Department of the Navy under the Department of Defense by order of the U.S. President or by act of Congress . Prior to its transfer to Homeland Security, it operated under the Department of Transportation from 1967 to 2003 and

7310-518: Was in World War II , in all some 250,000 served in the Coast Guard during World War II. Coast Guard Squadron One , was a combat unit formed by the United States Coast Guard in 1965 for service during the Vietnam War . Placed under the operational control of the United States Navy, it was assigned duties in Operation Market Time . Its formation marked the first time since World War II that Coast Guard personnel were used extensively in

7396-406: Was inconsistent and the system still relied on all-volunteer crews. In 1871, Sumner Increase Kimball was appointed chief of the Treasury Department's newly created Revenue Marine Division, and began the process of organizing the Revenue-Marine cutters into a centralized agency. Kimball also pushed for more funding lifesaving stations and eventually secured approval to create the Lifesaving Service as
