Field Activity 1985-021-FA

Identifier 1985-021-FA
Purpose Determine abundance of lobsters and lobster shelters in selected areas of the northwest region of the Gulf of Maine (Jordan Basin). Describe and record the geological and sedimentary features of the sea floor at all dive locations; collect sediment samples for grain size analysis and qualitative infaunal samples.
Location northern Jordan Basin, Gulf of Maine, United States, Canada, North America, North Atlantic;
Summary 10 submersible dives (JSL2-1089 thru JSL2-1098) observed/documented the sea floor and lobsters, and collected required sediment samples. Sediment samples: 18.
Info derived Samples and chemical analysis; Grain size analysis; Habitat maps;
