| Summary: | Chlorophyll a ancl carbon assimilation were studied during cruises 13, 14, and 15 of the RV Eltanin, operating in the Antarctic convergence region OF the South Pacific Ocean during May-December 1964. Chlorophyll a was generally distributed uniformly at differ: ent depths in the euphotic zone, varying with season and location, but the average ranged from 0.1 to about 0.3 mg/m”. Values up to 2.58 mg/m ” were observed in surface waters near New Zealand during December. On the three cruises, carbon assimilation (mg C m-” hr- ’ ) in surface waters, determined at light saturation in a fluorescent incubator, averaged 0.075, 0.154, and 0.366 at stations in the region south of the convergence and 0.216, 0.258 ancl 0.392 at stations just north of it. The average primary production (mg C mm2 day-‘; on cnch of the three cruises was 0.8, 26.3, and 152.2 south of the convergence and 2.2, 38.3, and 175.1 just north of it. This paper reports determinations of chlorophyll a and carbon fixation of phyto-plankton in water samples collected on cruises 13, 14, and 15 of the RV Eltanin in the South Pacific Ocean between Valpa- |
