No reference to the trip depth was found in the log books but John Morris from PBS confirmed that the niskin bottle was brought up to just below the surface and was tripped at approximately 1 to 3 m. The niskin was then sub sampled in the ocean lab for salinity, nutrients and chlorophylls. Analysis methods: ----------------- Salinity samples are collected in glass bottles and analyzed on Guildline model 8410 Portasal Salinometers which are standardized with IAPSO standard seawater. Nutrient samples are analyzed frozen using a Technicon AAII auto-analyzer following methods described in Barwell-Clarke and Whitney (1966). Chlorophyll samples are filtered onto 25mm MFS GF/75 or Whatman GF/F filters at <70mmHg vacuum. The filters are immediately frozen at -20 C until analysis. The chlorophyll is extracted in 10 ml of 90% acetone for 24h at -20 C, then brought to room temperature and the extract is measured using a Turner Designs fluorometer, which has been calibrated with solutions of commercially prepared chlorophyll.
