6. Chesapeake Bay Notes

  1. 1. Chesapeake Bay Notes<br />
  2. 2. Estuary:<br />Body of water where fresh and salt water mixes<br />Largest of the 130 estuaries in the United States<br />
  3. 3. Size of the Chesapeake Bay:<br />Pennsylvania<br />NJ<br />Volume: 15 Trillion Gallons<br />11,684 miles of shoreline<br />Maryland<br />Depth Range: 0-174 feet<br />Average Depth: 21 feet<br />DE<br />Virginia<br />3.4 miles to 25 miles wide<br />200 miles in length<br />
  4. 4. Watershed:<br />An area of land that drains to a particular river, lake, bay or other body of water<br />
  5. 5. Bay Creation - Meteor<br />A meteor crashed, setting the stage for the bay to be formed<br />The resultant crater is called the Exmore Crater<br />
  6. 6. Bay Creation - Glaciers<br />The movement and melting of the glacier during the last ice age caused the creation of the streams and rivers that make up the Chesapeake Bay<br />
  7. 7. Salinity of the Bay:<br />Salinity of the bay increases as you head south<br />Freshwater comes in from the rivers so the top is essentially freshwater<br />Increasing Salinity<br />
  8. 8. Composition of Water:<br />Sources of dissolved materials:<br />Decomposition of dead organisms<br />Live organisms releasing compounds directly<br />Organic and inorganic materials enter through tributaries<br />
  9. 9. Dissolved Gases:<br />Dissolved oxygen is affected by temperature and salinity<br />Dissolved carbon dioxide is necessary for plants and comes from respiration of organisms<br />Nitrogen and phosphorus are also necessary for organisms, however, due to run-off they can be in poisonous concentrations<br />
  10. 10. Food Web:<br />Most energy and largest volume of organisms found at the bottom<br />Less and less energy is transferred through each trophic level because it is used or lost as heat<br />Contaminants ingested by each level get passed along in increasing amounts through the food web<br />
