Station sampling (1)

• Bottom trawl at ≈350 stations each cruise

• Catch sorted to species

• Each individual measured

Station sampling (2)

• Age samples taken for commercially important species

• Stomach contents analyzed for most species

• Sex and Maturity

• Various special request samples

NEFSC Plankton Surveys• 6 times per year since 1971• CTD cast to within 5 m of sea

floor– Temperature, Salinity, Oxygen

• Plankton tow with bongo net– First net processed for

zooplankton– Second net processed for fish

larvae

• Dissolved Inorganic Carbon, Total Alkalinity, Nutrients at a subset of stations
