Summary Information for Field Activity 2005-039-FA

Area of Operations: Western Long Island Sound, New York, United States, North America, North Atlantic

Dates: October 14, 2005 to October 14, 2005

Chief scientist: Rick Rendigs

Objectives: Obtain diver push cores from selected sites in Western Long island Sound: Manhasset Harbor, Little Neck Harbor, and Hempstead Harbor - two cores from each site. CCNY to determine down-core concentration profiles of Chlordane and DDT.

Type of Activity: Sampling; SCUBA; diver push cores;SCUBA
diver push cores

Information to be derived: Samples and chemical analysis;

Summary: Collected a total of six push cores of at least 50 cm. in length. Bottom sediments very silty and underwater visibility was less than a few feet. The weather was lousy and the boat (32 ft. Sport Fisherman) was clearly not rigged for dive operations, but in true USGS fashion, we endeavored to endure and succeeded in spite of ourselves!!! Dives: 3 (One dive at each site); Cores: 6 (2 cores collected at each site); Analyses performed by scientists at CCNY.
