  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 fresh on board using a Technicon AAII auto-
    analyzer following methods described in Barwell-Clarke and Whitney (1996).

    Chlorophyll samples are collected in duplicate in calibrated polycarbonate
    bottles (~330ml), then filtered onto 25mm MFS GF/75 filters at <70mmHg
    vacuum. The filters are placed in glass scintillation vials and immediately
    frozen at -20ºC until analysis. The chlorophyll is extracted in 10 ml of 90%
    acetone for 24h at -20ºC, then brought to room temperature and the extract
    is decanted and measured using a Turner Designs 10-AU-005-CE fluorometer,
    which has been calibrated with solutions of commercially prepared
    chlorophyll.
