Abstract
The abundance and biomass of large diatoms retained in 100 μm mesh nets have been determined from 46°N to 15°S along 175°E in the central Pacific Ocean during August and October, 1991. Twenty-seven diatom species ranging from 13 × 103 to 34 × 106 μm3 in single cell volume were recognized in the samples obtained by a NORPAC net in the top 200 m of the water column at 13 stations in the area. Numerical abundance of each species within the top 50 m or 100 m which covered most of the euphotic zone, were mostly < 10 cells. M−3. Percentage shares of chlorophyll a of > 100 μm fraction which included large diatoms and dinoflagellates were always less than 5% of the total chlorophyll a in the water, and then the fraction of the large diatoms as a group in the total chlorophyll a were much less. The distribution of large diatoms in the area was largely classified into three types; distributed only at 44°N or north, at 30°N or north, and at 36°N or south. The second type partly overlapped the distribution of the first type at 44°N or north and the 3rd type at 30–36°N. There was the sub-Arctic front locating between 43°N and 42°N and a subtropical convergence at 28°N, which seems to be important for controlling the large diatom distributions.
