HOT Cruise Summaries

    Cruises are made to the HOT deep water station approximately once a month, and are denoted as HOT-n, where n is the sequential cruise number. HOT-1 was in October 1988.

    Station inventories are given in files with the extension "sum" (e.g., HOT-1 is summarized in hot1.sum.

    These summary files are written using formats specified by the WOCE Hydrographic Programme Office, and are detailed in the WHP Office Report WHPO 90-1, available from:

      WHPO Data Manager

      9500 Gilman Drive, La Jolla, CA 92093-0214.

    The station summary file contains the following columns:

    Country Code-Ship Code-Expedition Designation / Leg (EXPOCODE):
    This code allows for the indentification of cast. It consists of a 4 character NODC country-ship code, a maximum of 8 character cruise number followed by a "/" and leg number. For example, the EXPOCODE for HOT-13 on the Moana Wave would be 31MW013/1.

    WHP-ID:
    The WHP section designator.

    Station number:

    Cast number and type:
    The cast type is a three letter description
        (i.e., ROS = Rosette water samples plus CTD;
        CTD = CTD only
        LVS = large volume samples).

    Date:
      The date of the cast in MMDDYY.

    Time:
      The time taken at the beginning (BE), bottom (BO), and completion (EN) of the cast.

    Position:
      Positions are recorded as (D)DD MM.MM X, where X is N or S for latitude and E or W for longitude. The navigation system code has been set to GPS.

    Bottom depth:
      Depth meassured by shipboard echo sounder in meters. The nominal depth for Station 1 = 1500m and for Station 2 = 4750m.

    Height above bottom:
      Bottom depth less the maximum pressure sampled.

    Maximum pressure:
      The deepest pressure sampled.

    Number of bottles:
      The number of bottles used during the cast.

    Parameters:
      A list of the parameters measured from the water samples collected during the cast. The identification numbers are listed below.

        1 = Salinity
        2 = Oxygen
        3 = Silicate
        4 = Nitrate
        5 = Nitrite
        6 = Phosphate
        7 = Freon 11
        8 = Freon 12
        9 = Tritium
        10= Helium
        11= Carbon 14
        12= Carbon 13
        13= Krypton 85
        14= Argon
        15= Argon 39
        16= Neon
        17= Radium
        18= Radium 226
        19= o18/o16 ratio
        20= Stronitum 90
        21= Cesium 137
