Analyzes methods: ----------------- Surface water temperatures were measured from a bucket sample using a deck thermometer of +-0.1 degrees Celsius accuracy. The salinity determinations were made at sea using an Autolab Model 601 Mark III inductive salinometer. Accuracy using duplicate determinations is estimated to be +/- 0.003 ppt. Chlorophyll and nutrients were analyzed using methods from Bulletin 125 Fisheries Research Board of Canada 1960 "A manual of seawater analysis" J.D.H. Strickland and T.R. Parsons, and subsequent editions. Productivity rates are measured on samples incubated at surface temperatures and at simulated in situ radiation levels. Productivity values should be used with caution, Table 3 in reference 3 lists those samples where abnormal values occur. In the data report many productivity values were represented as "<.01". It is unclear what this means. In our files this value is indicated as "0.01" References: 1.
