Geography
Located between 23–35 ° C. w. and 30-68 ° C. The area of the region is 6-7 million km² (depending on the position of the currents). Located at a considerable distance from the coast. In the northwestern part are volcanic Bermuda . The water temperature on the surface is 18–23 ° C in winter, 26–28 ° C in summer. Salinity is 36.5—37 ‰ . Most of the bottom is located in the North American Basin with depths of more than 6,000 meters; maximum depth - 6995 m.
Large accumulations of floating brown algae - sargassa , within the sea its stock is estimated at 4-11 million tons. Their abundance is associated with the presence in the Sargasso Sea of a zone of convergence of surface currents. Numerous and diverse animals live, partly free- swimming ( mackerel , flying fish , sea needle , crabs , sea turtles , etc.), partly attached to algae ( sea anemones , bryozoans , etc.).
The bottom is covered with red clay and silts . Due to the specific circulation, the sea surface is almost 1 meter above the sea level. It is considered the only sea in the world that does not have solid coasts, but is limited only by currents . The first Europeans to see the Sargasso Sea were the sailors of Christopher Columbus . [1] .
In the Sargasso Sea there is a large garbage stain made of plastic and other wastes formed by ocean currents, gradually concentrating garbage thrown into the ocean in one area [2] .
