Presentation Transcript
wetlands
Wetlands
  • Wetlands contain fresh water for part of the year

-trap and filter sediments and pollutants

-protect shorelines from erosion

-spawning grounds for many commercially important species

-habitat for rare and endangered animals and plants

  • Includes marshes and swamps
  • Act as transitional areas between freshwater and saltwater
marine ecosystems
Marine Ecosystems
  • Estuary (FW and SW)
  • Salt marsh
  • Mangrove swamps
  • Barrier Islands
  • Coral reef
  • Open ocean
estuary
Estuary
  • area where freshwater from a river meets salt water from the ocean

-very productive ecosystems

-rich in nutrients and minerals

-plenty of sunlight (shallow water)

salt marsh
Salt marsh
  • Develop in areas where estuaries deposit nutrient rich mud
  • Characterized by marsh grass
  • Provide support for clams, fish, crabs, shrimp, and aquatic birds
  • Absorb pollutants and protect
  • inland areas
mangrove swamp
Mangrove Swamp
  • tree vegetation that grows in the muddy coastal areas between high and low water
  • mangrove forests protect the coastline from erosion; provide nursery grounds for fish, shrimp, clams, crabs and snails
  • provide food via
  • nutrient-rich mud
  • and leaf litter.

Approximately one-third of all marine biological productivity occurs along coastal areas. These areas include mangroves, salt marshes, tidal zones and sea grass beds.
barrier island
Barrier Island
  • These geographic features serve as protection for mainland and coastal wetlands
coral reef
Coral Reef

One of the worlds most biologically diverse ecosystems

42% at low risk

31% at medium risk

27% at high risk

open ocean
Open Ocean
  • Represents 65% of the Earth oceans.
  • Some areas of open ocean contain little or no life at all, while other areas support large numbers of species
  • Approximately 10% of all
  • marine life is found in the
  • open ocean.

Marlins, Tuna, Dolphins, Swordfish, and Sharks.
