Oceans and Climate Branch CTD Data Report HB 1901 Spring Bottom Trawl Survey

This report presents a summary of surface and bottom temperature and salinity data collected during the Northeast Fisheries Science Center’s HB1901 Spring Bottom Trawl Survey aboard the NOAA FSV Henry B Bigelow. Data was obtained with a Sea-Bird Electronics SBE Model 19+ profiling CTD (s/n 4684) during double oblique bongo tows and on vertical casts with a SBE Model 9/11+ s/n 0832. Sea water samples were taken for the purpose of calibrating salinity values. An SBE43 Dissolved Oxygen sensor and a Biospherical Instruments Inc. QSP2300 PAR (Photosynthetically Active Radiation) sensor were attached to the SBE 9/11+. A QSR2200 Surface PAR sensor was located on the flying bridge and relayed data in realtime to the 9/11+ deck unit. The PAR data obtained during the vertical profiling casts is included in the archived CTD data; the surface PAR data will be made available on request. Data presented here have been audited, however, corrections and/or updates may be applied at a later time. 2020 NMFS (National Marine Fisheries Service) NEFSC (Northeast Fisheries Science Center) Submitted https://doi.org/10.25923/r0v8-ne92 Public Domain 1930
