Productivity and chlorophyll surface samples were taken between 0600 and 0900 local time with a plastic bucket. Analyzes methods: ----------------- Salinity samples are analysed immediately after returning to th lab in a modified Wenner-Smith-Soule conductivity bridge. The accuracey of the salinity analyses is +-0.01 ppt. Photosynthesis was measured in 300 ml volumes of sea water by the carbon-14 method. Plant pigments were measured in samples having a minimum volume of 2 litres, using a modification of the Richards method. The procedures descri by Strickland and Parsons (1960) were followed. Plant pigments were analyzed at sea, using a Beckman DU spectrophotometer. The HA milipore filters containing the radioactive plankton for determinatio of carbon-14 uptake were glued to copper planchets, stored over silica gel and soda lime, and were usually analyzed at the base laboratory ashore. Duri surveys P-59-3, P-60-1 and P-60-3, radioactivities were measured aboard ship Tests have shown that there is no significant change in activity during the 6- to 8-week storage period undergone by samples held for analysis ashore. Radioactivity was determined in a Tracerlab windowless flow counter. The light intensities reported here are taken from transcripts of continuous records of solar radiation obtained using an Eppley pyrheliometer. Photosynthetic radiation was assumed to be 50% of that measured by the pyrheliometer. The complete radiation data are reported in the Monthly Radiation Summary published by the Meteorological Branch, Department of Transport, Canada. Method of incubation of samples for measurement of photosynthesis ----------------------------------------------------------------- Photosynthesis was measured in individual samples from 6 depths between the surface and 100 m, held under blue and green fluorescent lamps giving an intensity of approximately 0.07 langley/min. Locations are given as the mid-point of grids approximately 20 minutes in latitude by 30 minutes in longitude. References: 1.
