    Contents:
    Bottle data from Weathership program using ships Vancouver & Quadra from
    Vancouver Island, BC, Canada to Ocean Weather Station P [50N x 145W].

    Sample collection methods:
    --------------------------
    Sea Water Temperature:
    - Reversing thermometers mounted on Nansen samplers
    Salinity:
    - Collected in Nansen samplers
    Dissolved Oxygen:
    - Collected in Nansen samplers
    Reactive Nutrients (Phosphate, nitrate, silicate):
    - Collected in Van Dorn samplers (productivity casts) or Nansen
    bottles (hydrographic casts).
    Biological and Productivity:
    - Collected in Van Dorn samplers.

    Analyzes methods:
    -------------------------
    Temperatures at depth were measured by deep-sea reversing thermometers of
    German (Richter and Wiese) or Japanese (Yoshimo Keiki Co.) manufacture. Two
    protected thermometers were used on all Nansen 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 an Auto-Lab Model 601 MK III
    inductive 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 for analyzes ashore.

    Chlorophyll and nutrients were analyzed using methods from Bulletin 125
    Fisheries Research Board of Canada 1960 "A manual of seawater analysis"
    J.D.H. Strickland and T.R. Parsons, and subsequent editions.
