This dataset contains optical and physical data collected on R/V Albatross IV, R/V Endeavor, R/V Oceanus, and R/V Seward Johnson during cruises AL9403II, AL9508, AL9605, AL9701, AL9707, AL9801, AL9806, AL9808, AL9901, AL9906, EN261, EN263, EN265, EN268, EN276, EN278, EN282, EN320, EN325, OC300, OC302, OC319, OC336, OC341, SJ9503, SJ9505, and SJ9507 in the Gulf of Guinea, Mediterranean Sea, Mediterranean Sea - Western Basin, North Atlantic Ocean, North Pacific Ocean, and Tyrrhenian Sea from 1994-05-17 to 1999-06-24. These data include light transmission (volts), potential temperature, salinity calculated from CTD primary sensors, sigma-theta, water pressure, and water temperature. The instruments used to collect these data include MOCNESS.25, MOCNESS1, and MOCNESS10. These data were collected by Dr Greg Lough, Dr John Green, and Ms Maureen Taylor of National Marine Fisheries Service, Dr John Sibunka of National Oceanic and Atmospheric Administration, Dr Charles B. Miller of Oregon State University, Dr Ann Bucklin of University of New Hampshire, Dr Dian J. Gifford and Dr Peter Garrahan of University of Rhode Island, Professor Steve M. Bollens of Washington State University, and Dr Peter H. Wiebe of Woods Hole Oceanographic Institution as part of the "U.S. GLOBEC Georges Bank (GB)" project and "U.S. GLOBal ocean ECosystems dynamics (U.S. GLOBEC)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2019-01-30.
The following is the text of the dataset description provided by BCO-DMO:
CTD data collected during MOCNESS hauls, Georges Bank, 1994-1999.
Dataset Description:
The MOCNESS is based on the Tucker Trawl principle (Tucker, 1951). The particular MOCNESS system from which these CTD data came is one of three net systems. The MOCNESS-10 (with 10 m 2 nets)carries 6 nets of 3.0-mm circular mesh which are opened and closed sequentially by commands through conducting cable from the surface (Wiebe et al. , 1976). In all three systems, "the underwater unit sends a data frame, comprised of temperature, depth, conductivity, net-frame angle, flow count, time, number of open net, and net opening/closing, to the deck unit in a compressed hexadecimal format every 2 seconds and from the deck unit to a microcomputer every 4 seconds... Temperature (to approximately 0.01 deg C) and conductivity are measured with SEABIRD sensors. Normally, a modified T.S.K.-flowmeter is used... Both the temperature and conductivity sensors and the flowmeter are mounted on top of the frame so that they face horizontally when the frame is at a towing angle of 45deg... Calculations of salinity (to approximately 0.01 o/oo S), potential temperature (theta), potential density (sigma), the oblique and vertical velocities of the net, and the approximate volume filtered by each net are made after each string of data has been received by the computer." (Wiebe et al. , 1985) In addition, data were collected from four other sensors attached to the frame: the Transmissometer, the Fluorometer, the Downwelling light sensor, and the Oxygen sensor. A SeaBird underwater pump was also included in the sensor suite.
It should be noted that whenever the data are of questionable value, "50.000" is written in the particular data field.
The following notes are cruise-specific:
OC319: Lats and Lons for first two tows are missing because gps string not yet available.
Unless otherwise indicated, these data have not been post-processed.
For additional information, contact the for the cruise or the (DMO).
Note: Some variables have been eliminated from the display but are nevertheless available. These variables include: oxycurrent, oxytemp, tempco, and echo.
