Testing

The 1995 and 1996 bottle data were collected with a GO rosette mounted above the MK5 CTD. Water for chlorophyll extractions was taken at priority 1 and 2 stations and at 3 'standard' depths (according to a protocal set up by Ted Durbin and Dian Gifford at the University of Rhode Island). For each bottle, 3 replicate samples were run for consistency. 50 mls were filtered for 3 size fractions: total chlorophyll, chlorophyll from water filtered through a <20 micron mesh and chlorophyll from water filtered through a <5 micron mesh. This means that for any one station, there were 27 test tubes: 3 depths, 3 replicates, 3 size fractions. The samples were usually read at sea (after the 24 hour acetone extraction). If not, Ted Durbin's Lab read them when the ship returned.
