  5. Moving to the Oceans –Estuaries 15 8th Grade Science Copy items in red and images indicated.

  6. River Estuary Coastal Ocean Estuaries Draw picture Estuary: is a body of water, partially enclosed by land, where fresh water from a river mixes with salt water from the ocean. Water in Estuaries is Brackish. Brackish means partly fresh and partly salty.

  7. Schematic of a typical Estuary

  8. Estuary images

  9. Neuse River Estuary Very Salty Neuse River Very Fresh

  10. Neuse River Basin

  11. NC largest Estuary is the Pamilco Sound Neuse River

  12. Filtering System • Estuaries clean our rivers by removing….. Sediment and Pollutant. This makes me think of…______

  13. Sediments • Sediment – Soil particles and chemicals carried by the river • Carrying of soil  Muddy estuaries • Soil can smother fish eggs, aquatic insects, and plants with mud. • Erosion of land  Chemical deposits • Chemicals can kill life

  14. Some estuaries are actually salt marshes. • These plants and mud take up some of the sediments and pollutants! • Animation of salt marsh • Salt Marsh Filtering • http://oceanservice.noaa.gov/education/kits/estuaries/media/supp_estuar03a_marsh.html

  15. Pollutants • Pollutants: Pesticides, sewage and industrial waste • Estuaries are a type of environmental filter. • Plants and animals in estuaries filter pollutants out of the water.

  16. Pollutants • Ex: Salt Marsh Plants trap some of the chemicals and pathogens carried by rivers and move them into soils where they can be neutralized. • Ex: Oysters filter impurities out of the water as they eat, collecting contaminants in their bodies. One oyster can filter 25 gallons of water per day

  17. Too many toxins can accumulate in estuaries causing many environmental and health problems

  20. What is an estuary? • The land area that drains water into a lake, river, or pond. • The area where a river meets the ocean, where fresh and salt water mix. • The large body of salt water that covers most of the earth’s surface • The underground system that provides drinking water to an area

  21. Which letter marks the estuary on the diagram?

  22. Estuaries have also been called? • Bays • Lagoons • Sounds • Sloughs • All of the Above

  23. Why are estuaries important to our environment? • They provide homes for many species of wildlife • They are important nursery areas for a variety of marine life • They help to filter pollutants from the water • All of the above

  24. How are estuaries connected to oceanic organisms? • Estuaries provide a nursery grounds for oceanic organisms • Estuaries provide sunlight for oceanic organisms. • Estuaries provide primary food for oceanic organisms. • Estuaries provide excess dissolved oxygen for oceanic organisms
