The deep water on the continental shelf south of Montauk Point, Long Island, remains cold throughout the summer. Since this cold‐water pool is surrounded by warmer water, it appears to be formed in the winter and to persist, with only gradual modification, for several months. The temperature and salinity of the water in this area have been observed on 20 cruises made during a 3‐year period. The cycle of temperature is described. The salinity changes in the deep water as it gradually warms are used to evaluate qualitatively whether the temperature change in each year was associated with admixture of higher‐salinity warmer offshore waters or lower‐salinity, warmer surface waters. The average salinity of the water on the continental shelf was closely correlated with the 6‐month average river flow of the Connecticut River, and it is shown that the salinity can be predicted to within error of estimate of approximately 0.3‰ from this river flow.
