6/22/20156SALINITY Salinity is measured in parts per thousand 0/00 This means how much salt (particles) there are in a thousand parts of water Varies from fresh in the North to salty in the South Salinity is greater at bottom due to gravity Euryhaline is an organism that is tolerant to salinity changes Has tides twice a month called Semi-diurnal

6/22/201510 At the end of the last glacial epoch, sea level rose relatively rapidly as continental glaciers melted. 10,000 years ago, the main channel of the ancient Susquehanna River valley was flooded and became a narrow estuary. SEA LEVEL RISE SEA LEVEL RISE

FREDERICK DOUGLASS USED THE CHESAPEAKE BAY TO ESCAPE SLAVERY BETWEEN 1700 AND 1770, SLAVE POPULATION GREW IN THE CHESAPEAKE BAY REGION FROM 13,000 TO 250,000 USING THE UNDERGROUND RAILROAD, AFRICAN AMERICANS CROSSED THE CHESAPEAKE BAY TO ESCAPE TO THE NORTH

6/22/201524Reptiles Turtles are the only reptiles with hard carapaces that do not have teeth. The two most common turtles found in the Chesapeake bay are the diamondback terrapin and the snapping turtle. The loggerhead turtle is found in the lower part of the Chesapeake bay. Both the Green Sea Turtle and the Kemp’s Ridley Turtle are found off of our coast.

6/22/201527 RESIDENT BIRDS Resident birds are mainly found on the Western shore of the Chesapeake Bay in urban and suburban areas. Canada geese is one type of Resident bird. Their migration route takes them along the eastern shore of Hudson bay& James bay across central New York.

6/22/201529 BIRD REFUGES Refuge provides habitat for migrating and wintering waterfowl. During the fall and winter months, Snow and Canada geese, tundra swans, and many duck species are abundant. Migrating songbirds and shorebirds arrive at the Refuge each spring.

6/22/201531Mammals Deer,raccoons, fox, squirrels, rabbits, and opossum are the most plentiful mammal residents of the Chesapeake Bay area. Noted aquatic mammals living here are otters, dolphins, porpoises, and whales.

6/22/201534Algae Phytoplankton grow in the photic zone or the depth to which sunlight penetrates the water. They undergo algae blooms or rapid population growth caused by excess nutrients. Major groups of phytoplankton are Diatoms, Green algae, Dinoflagellates. They are used as indicators for environmental conditions within the bay.

6/22/201536 Bald Cypress Grow to be 100 to 120 feet tall and 6 feet in diameter. Usually abundant in muck, clay or fine sand where its very high amount of water.

6/22/201538 Loblolly Pine This rapidly-growing tree thrives in the maritime forest, at the bay’s edge. It prefers the Bay's relatively long, hot and humid summers. The trees provide important nesting habitat for bald eagles and osprey. Loblolly pines are frequently used for soil stabilization in areas that are subject to severe erosion.

6/22/201540 American Holly American Holly is used as a popular holiday decoration. Bluebirds, and songbirds use holly for shelter and raising their young. Native Americans used the wood and berries for bartering and decorating.

43
6/22/201542 Bay Grasses In the shallow waters of the bay, many underwater grasses thrive. These grasses are also known as submerged aquatic vegetation, or SAV, that grow completely underwater. SAV have additional support that causes easier exchange of gasses.
44
6/22/201543 Bay Grasses SAV play an important role in bay ecology by performing many functions. Some of these include providing food and habitat, filtering sediment, producing oxygen, and protecting the shoreline from erosion. They also remove excess nutrients from the water which prevents overgrowth of algae.

6/22/201552 Most biologically productive estuary in North America. More seafood is harvested from Chesapeake Bay than any of the other 840 U.S. estuaries. Blue crab harvest is > 1/2 of U.S. total harvest.
54
6/22/201553Businesses Tourism is a major factor in the businesses around the Chesapeake Bay. Restaurants, hotels, bait shops, water sport rentals, and marinas are most commonly found on the Bay. Businesses for the Bay is a voluntary team of enterprises within the Chesapeake Bay watershed. More and more businesses are forming in order to prevent pollution.

6/22/201555Factories Smithfield Factories is one of the largest industries responsible for the pollution of the Chesapeake Bay. In August 1997, a federal judge in Virginia fined the Smithfield pig processing plant $12.6 million for the plant's chronic dumping of slaughterhouse wastes into the Pagan River, a tributary of the James River and Chesapeake Bay.

Fort Story is where the Cape Henry lighthouse is and where settlers first landed. Langley Air Force Base is the oldest Air force base that has remained continuously active. Oceana Naval Air Station was carved out of swampland and has grown 16 times larger. Dam Neck Base is directly on the beach and has the most military beach access.

6/22/201575POLLUTION The biggest problem is nutrient pollution. Nutrient pollution is caused by excess nutrients, nitrogen and phosphorus. SAV’s are destroyed. Toxic chemicals, air pollution, sedimentation, and the over-harvesting of living resources can pollute.

IN THE 1970’S, CONGRESS PASSED THE CLEAN AIR ACT AND THE CLEAN WATER ACT CITIZENS FORMED WATERSHED GROUPS AND OFFICIALS BANNED PESTICIDES AND TOXIC CHEMICALS IN 1983, THE BAY RESTORATION ACT REPLACED THE CHESAPEAKE BAY AGREEMENT
