04.02 Biosphere

Depths of the Gulf:-The deepest part of The Gulf of Mexico is called Sigsbee deep. It is 12,00 feet deep ad over 300 miles long. Some call it " The Grand Canyon of The Sea".

Effects of Sunlight on the aquatic life of The Gulf of Mexico:-Sometimes heat can determine the sex of certain creatures, for example sea turtles.- Plant life and algae depend on sunlight for photosynthesis- So say that a certain area of water by the coast is coverd by a tree , there would not be as much moss, or plant life there becasue of th lack of sunlight.

Environmental ConcernsRe-engineering the Mississippi River has unintentionally reduced the flow of land-building sediment to the Gulf coast by half and sends much of that past the wetlands to deep water. Diversion projects could reverse the decline of coastal wetlands by making use of what we have left.It is estimated that 50 percent of the Gulf of Mexico’s inland and coastal wetlands have been lost and that up to 80% of the Gulf’s sea grasses have been lost in some areas.The Gulf of Mexico is home to 24 endangered and threatened species and critical habitats.Relative sea level rise along most of the Gulf coast has been substantially higher than the global average due to local land subsidence combined with the increasing volume of water in the sea.Padre Island has been inundated by as much as one ton of debris per mile.

Location and Geological Description- The Gulf of Mexico borders the united States, Mexico, and Cuba.-The Gulf of Mexico is located 25.0000° N and 90.0000° W - The gulf is a large ocean basin- The gulf is over 600,000 square miles and is one of the largest bodis of water in the world.- The gulf is fed water by 33 major rives. One of the Mississippi River, which is the largest in the United States.

Salinity:The average salinity of the ocean is 35 ppt (parts per thousand). Most of the Gulf's salinity will average from 28 to 32 ppt. Some areas can average at 38 ppt."Brine pools and seeps from the bottom of the Gulf of Mexico basin contribute higher salinity water to the Gulf and significantly raise the salinity near these features. Ecosystems and the life forms that exist in high salinity environments are very different from those found elsewhere".http://www.create.cett.msstate.edu/cosee/cosee-lplan_view.asp?articleid=74

Effects of seasonal change on the Gulf.- The shallower the water the greater the change in temperature during seasonal changes.- When temperature outside increases there is more evaporation, therefore more percipitaion. When the amount of rain increases the rivers grow, thus more water traveling into the gulf.- If there is a drastic change in water temperaure certain species will begin to die off becasue they have not adapted to that kind of enviornment.
