    Collection method:
    ------------------
      A rosette, holding 24 ten-litre water samplers, with a CTD was used.

    Analysis methods:
    -----------------

      Salinity samples are collected in glass bottles and analyzed on Guildline
      model 8410 Portasal Salinometers which are standardized with IAPSO standard
      seawater.

      Oxygen samples are analyzed on an automated Winkler titration system
      following the procedures of Carpenter (1965). A Brinkmann model 665 Dosimat
      and model PC910 Colorimeter is controlled by Visual-Basic program to
      titrate the oxygen samples.

      Nutrient samples are analyzed frozen using a Technicon AAII autoanalyzer
      following methods described in Barwell-Clarke and Whitney (1996).

      Chlorophyll was extracted with 90% acetone and analyzed fluorimetrically.
