    data processed by Bernard Minkley

    Sample collection methods:
    --------------------------
    Sea Water Temperature:
    - Reversing thermometers mounted on bottles.
    Salinity:
    - Collected in bottles.
    Dissolved Oxygen:
    - Collected in bottles.
    Reactive Nutrients (Phosphate, nitrate, silicate):
    - Collected in bottles

    Analyzes methods:
    -------------------------
    Temperatures at depth were measured by deep-sea reversing thermometers of
    German (Richter and Wiese) and/or Japanese (Yoshimo Keiki Co.) manufacture.
    Two protected thermometers were used on all bottles, and one unprotected
    thermometer was used on each bottle at depths of 300 m or greater. The
    accuracy of protected reversing thermometers is believed to be +-0.02C.

    Salinity determinations were made at sea with a Guildline Autosal
    salinometer. Accuracy using duplicate determinations is estimated to be
    +-0.003 ppt.

    Depth determinations were made using the "depth difference" method
    described in the U.S.N. Hydrographic Office Publication No. 607 (1955).
    Depth estimates have an approximate accuracy of +-5 m for depths less than
    1000 m, and +-0.5% of depth for depths greater than 1000 m.

    The dissolved oxygen analyses were done in the shipboard laboratory by a
    modified Winkler method (Carpenter, 1965).

    Nutrient samples were frozen onboard for analysis onshore.

    Chlorophyll concentration was estimated from fluorescence of aqueous acetone
    extracts from filtered samples. Analysis methods generally followed those
    described in Parsons et al. 1972, however there have been various
    modifications of filtering and extraction protocols. Contact data
    originator(s) for details specific to individual time periods.
