Estuaries

Estuaries Miles Bryan Matthew Okoneski Justin McCotter Definition of Estuary Estuary: Any body of water where freshwater and saltwater mix. Transition area from land to sea Often called bays, lagoons, and sounds Ex: Pamlico sound, Chesapeake Bay Contains many different habitats

Deltas and Estuaries

Deltas and Estuaries. Deltas. From the Greek letter, based on the shape of the Nile River delta Occur where river supplies a large enough amount of sediment Empties directly to sea (not into estuary; estuary is filled in)

Estuaries

Estuaries. Introduction. We’ve already seen what it’s like near the edge! Ocean life is rough. Adaptation is the key to long term survival. What about in environements which appear to be less disturbed? Does chaos still rule in a world of “living on the edge,” such as estuaries?

Rivers and Deltas

Rivers and Deltas . Jeishla Lopez. Features and characteristics of this landform. A delta is the opening where a river forks off into smaller streams, emptying into a larger body of water. Deltas are at the mouth of large river systems that carry large quantities of clastic sediments.

ESTUARIES

Estuaries - partially enclosed, coastal and transition areas where fresh water from rivers mixes with seawater ( called brackish ). ESTUARIES. U.S. has nearly 900 estuaries, many of which were formed at the end of the last glacial period by rising sea level.

Deltas

Deltas. What is a Delta?. Deltas are landforms of deposition They are formed in the lower course of a river. They are named after the third letter of the Greek alphabet ( Δ ). How can you recognise a Delta?. River enters a lake or sea, velocity and capacity to carry a load is reduced.
