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 ashore using an Autolab Model 601 Mark III inductive salinometer. Accuracy using duplicate determinations is estimated to be +/- 0.003 ppt.
