  1. Estuaries By: Ms. Messer

  2. Where in the world? These are found where freshwater from rivers and streams meets and mixes with salt water from the oceanalong a coast.

  3. Estuaries in the US

  4. Abiotic Factors of an Estuary Mixture of fresh and saltwater Temperatures are consistent year round because of the connection to the ocean, but will depend on the depth of water Typically large amounts of rainfall in the summer months, but a yearly average of 50-60cm of rain. Estuaries typically experience all four seasons

  5. Plants found in Estuaries Mangroves Seagrass Purple Loosestrife

  6. Animals found in Estuaries Mud Crab Cockles White faced heron

  7. Plant Adaptations Plants that grow in estuaries must contend with exposure to wind and strong currents, as well as low oxygen levels and salty conditions. They have adaptations to tolerate high levels of salt in the water.

  8. Animal Adaptations Read about the adaptation of the blue crab.

  9. Symbiotic Relationships in Estuaries Commensalism- Barnacles are a well-documented example of commensalism. They hook themselves to another organism such as a fish, and while they don't really harm it, they do get some benefit by having a place to stay. It also helps that this means they are dragged through the water quickly, since they are filter feeders.

  10. Why should I visit an estuary? Boating, fishing, swimming, surfing, and bird watching are just a few of the numerous recreational activities people enjoy in estuaries. Unique estuarine habitats makes them valuable laboratories for scientists and students. Estuaries also provide a great deal of aesthetic enjoyment for the people who live, work, or use them for recreation.

  12. Environmental Threats to Estuaries Because we use the coastline for recreation, we are endangering our estuaries by polluting the water and building on the lands surrounding them. These activities can contribute to unsafe drinking water, beach and shellfish bed closings, harmful algae blooms, declines in fisheries, loss of habitat,fish kills, and a host of other human health and natural resource problems.

  13. Endangered Species in an Estuary West Indian Manatee Green Sturgeon

  14. Endangered Species in Estuaries The species on the previous slide are endangered due to human activities such a boating, pollution from boats, and climate change (increasing global temperatures from too much carbon dioxide produced).
