Marine ecosystems

  1. 1. Marine and Fresh Water
  2. 2. Marine Ecosystem
  3. 3. Marine Ecosystems
  4. 4. Types of Marine Ecosystems  Estuaries  Salt marshes  Rocky shores  Sandy Shores  Coral reef  Mangrove swamp  Barrier islands
  5. 5. Estuaries An area in which fresh water from a river mixes with salt water from the ocean; a transition area from the land to the ocean. Other names: bay, sound, lagoon, harbor, or bayou. The Ocean Area where fresh and salt water mix River bringing freshwater to the sea
  6. 6. Characteristics of Estuaries  Very nutrient rich ecosystems  leads to high productivity and high biodiversity.  Fast-moving rivers and waves carry nutrient-rich particles.  Sediment settles out in the estuary when the water slows down.  Nutrients accumulates on the bottom (benthic zone).  Great place for plants to grow!
  7. 7. Estuary plants Plants must be adapted to salty habitat eelgrass cordgrass glasswort – a succulent
  8. 8. Estuary animals Huge variety including… Blue crab, Stone crab, Fiddler crab, Horseshoe crab, Mosquito, Lobster, Flounder, Stripped bass, Crane, Flamingo, Sea gull, Ibis, Manatee, otters, and many more.
  9. 9. Salt Marshes  A low area that is subject to regular, but gentle, tides, dominated by grasses.  Salt marshes do not have trees or shrubs Texas salt marsh
  10. 10. Mangrov e Swamps Coastal wetlands located in tropical and subtropical zones; characterized by salt-tolerant trees and shrubs, such as mangrove trees
  11. 11. Rocky shores Also called rocky intertidal zone – many places to live in this habitat, means high biodiversity Organisms must be adapted to wave action, changing tide levels
  12. 12. Rocky Shores At low tides, there are often tide pools left behind where you can see starfish, anemones, crabs, octopus
  13. 13. Sandy Shores Sandy shores or beaches are loose deposits of sand, gravel or shells that cover the shoreline in many places. They make up two-thirds of the world’s ice-free coastlines.
  14. 14. Barrier Islands A long, narrow, offshore island, usually having beaches and dunes on the seaward side,often with lagoons on the landward side
  15. 15. Coral Reefs  Structures in the shallow oceans that are built by animals called corals; serve as a habitat for many diverse organisms  Require two things: warm temperatures and sunlight  Found between 30°N and 30°S of the equator
  16. 16. Coral Reefs There are many different kinds of corals: Soft corals Hard corals
