ESTUARIES

What is an estuary? Area where fresh water meets salt water Semi-enclosed Transition zone Includes bays and lagoons

Chesapeake Bay, a coastal plain estuary Nauset Barrier Beach – Cape Cod

San Francisco Bay, a tectonic estuary Fjords

NJ ESTUARIES

What conditions affect estuaries? Rivers bring in: –Fresh water –Sediment –Pollutants from land Oceans bring in: –Salt –Sandy substrate –Plankton Estuary salinity Mudflats

Estuaries are also affected by: TemperatureSunlightRainfall Tides & Currents

Productivity Very high rate of productivity Water in estuary is nutrient-rich: –Nutrients are carried from freshwater –Insoluble in salt water Many nutrients are good for producers

Organisms Some are permanent part of estuary community Some come and go: plankton, salmon, birds, horseshoe crabs Some land animals that interact with aquatic organisms

TYPES OF COMMUNITIES Open Water Mud flats –Exposed at low tide Salt marsh (temperate) –Partially flooded at high tide Mangrove forest –Tropical equivalent of salt marsh Mud flat Salt Marsh Mangrove forest

HUMAN IMPACT Coastal development PollutionDredging Clearing Land –Erosion
