Estuarine ecology

You Estuarine ecology visitor number since 16 December Oxygen is fundamental to life. Tectonically produced[ edit ] These estuaries are formed by subsidence or land cut off from the ocean by land movement associated with faultingvolcanoesand landslides.

Excess oxygen-depleting chemicals in the water can lead to hypoxia and the creation of dead zones. They also accumulate in benthic environments, such as estuaries and bay muds: Chesapeake Bay once had a flourishing oyster population that has been almost wiped out by overfishing.

Amazon estuary The word "estuary" is derived from the Latin word aestuarium meaning tidal inlet of the sea, which in itself is derived from the term aestus, meaning tide. The invention and use of chemical fertilizers and growing human populations have led to an explosive increase in the number of sites around the world that experience hypoxia.

Oysters filter these pollutants, and either eat them or shape them into small packets that are deposited on the bottom where they are harmless. There is extreme spatial variability in salinity, with a range of near zero at the tidal limit of tributary rivers to 3.

No points of attachment exist for algaeso vegetation based habitat is not established. The main phytoplankton present are diatoms and dinoflagellates which are abundant in the sediment.

My one page resume is available in html and PDF formats. Barrier beaches form in shallow water and are generally parallel to the shoreline, resulting in long, narrow estuaries.

Like hypoxia, acidification results from respiration by plants and animals in our oceans and coastal waters because respiration that consumes oxygen also produces carbon dioxide, which acidifies water.

There have been many definitions proposed to describe an estuary. Finally, warming of surface waters increases the difference in density between surface and deeper water layers, which reduces contact between subsurface waters and the oxygen-rich atmosphere. They move with the water bodies and can be flushed in and out with the tides.

Initially, these nutrients stimulate production of phytoplankton just as fertilizers stimulate growth of grass on lawns and agricultural crops on farms.
