is the sea of galilee salt water or freshwater?
freshwater
the natural hydrology of fritchie marsh heavily depends on deposits from the west pearl river. the west pearl river provides the area with freshwater, nutrients, and the sediment that is necessary to sustain a freshwater marsh. however, the enclosure of fritchie marsh by its bordering highways cut the area off from many of the necessary deposits coming from the west pearl river. a small culvert placed under louisiana highway 90 allowed minimal input into fritchie marsh from the west pearl river. at the same time, salt water spills into the area from lake pontchartrain through little lagoon and the w14 canal located along the louisiana highway 433 eastern border. the salt water penetration was not continuous but occurred frequently during strong winds and high tides. the combination of damaging salt water breaches along with the lack of freshwater and sediment input into fritchie marsh resulted in a shift away from freshwater marshland of 1956 towards a nearly brackish marshland visible by 1990. some conservations believed that if allowed to continue with this trend, fritchie marsh would be destroyed and would be converted into an open body of salt water.

in the baltic sea, the input of salt water from the north sea through the danish straits is important in determining the area of hypoxia each year. denser, saltier water comes into the baltic sea and flows along the bottom. although large salt water inputs help to renew the bottom waters and increase oxygen concentrations, the new oxygen added with the salt water inflow is rapidly used to decompose organic matter that is in the sediments. the denser salt water also reduces mixing of oxygen poor bottom waters with more brackish, lighter surface waters. thus, large areas of hypoxia occur when more salt water comes into the baltic sea.
