Phytoplankton samples are routinely taken at every station on Brookhaven oceanographic cruises. On productivity stations samples are taken from every depth, while on hydrographic stations samples are taken from the surface and some fixed depth (e.g. 20 m). The 125 ml samples are drawn as soon as possible after the cast from Niskin bottles and preserved with 2-3 ml of Lugol's solution. The samples are left in dark boxes in cool areas until counted. For counting, 10 ml subsamples are settled in Uttermohl chambers, usually within three months after the cruise, and counted with an inverted microscope equipped with phase contrast illumination. Between one-half and the entire chamber are counted, depending on the cell density. This data report is a listing of the phyto- plankton counts from selected stations and cruises between 1976 and 1978, inclusive
