Copepods collected along 13゜E longitude of the Antarctic Ocean in the 1973 summer
Zooplankton samplings were conducted at 8 stations in the Indian sector of the Antarctic Ocean along 13°E from 27 February to 3 March in 1973 by the 14th Japanese Antarctic Research Expedition. Vertical hauls from 200m to the surface with a Norpac net (45cm in diameter, 0.33mm mesh openings) were ca...
