  1. An Overview of Barnegat Bay New Jersey What Shapes the Bay OCC ENVI 152 Fall 2013

  2. Barnegat Bay is one of 28 Estuaries in the United States to be funded through the National Estuary Program Manasquan Inlet Barnegat Inlet Little Egg Inlet Over 550,000 people now reside in the Barnegat Bay Watershed (2010)

  3. N Barnegat Inlet The length of Barnegat Bay is approximately 64 km

  4. Barnegat Bay and its Watershed encompasses over 660 square miles (BBEP Characterization 2001) The entire Barnegat Bay system has a mean 50 day flush rate (over 30 days in winter and 74 days in summer (Kennish).

  5. Estuaries as Habitats • Estuaries provide multiple habitat types including marshes, marsh pools, tidal creeks, and shoreline deep water habitats • Finfish can inhabit specific habitats with fish being considered seasonal residents (19%), residents (21%), nursery (38%) or strays (22%) in a study on Great Bay and Little Egg Harbor (Able et al. 1996 in Estuarine Shores).

  6. Submerged Aquatic Vegetation • In some estuaries over 300 species of fish reside all in which SAV is important: • Provide habitat for juveniles • Key source of oxygen production • Important part of nutrient cycling • Binds and stabilizes sediments

  7. Marsh Zonation • High Marsh – Not flooded regularly with predominant Spartina patens and Phragmites • Series of marsh pools at higher elevations • Low Marsh – Floods regularly with Spartina alterniflora • Creeks and ditches with sometimes tidal effects • Support a higher density of finfish than SAV beds (Sogard and Able 1991).

  11. Barnegat Bay: Anthropogenic Effects • Nutrient Runoff makes it a highly eutrophic system (US EPA) • Thermal Pollution from surface water cooling system at the Oyster Creek Nuclear Generating Facility • Reduction in shellfish stocks due to changes in water quality, specific shellfish diseases and consumption
