Copepods collected along 33.5゜E longitude of the Antarctic Ocean in the 1976 summer
Zooplankton samplings were conducted at 6 stations along 33.5°E in the Indian sector of the Antarctic Ocean from 25 February to 2 March in 1976 by the 17th Japanese Antarctic Research Expedition. Vertical hauls from a depth of 200m to the surface with a Norpac net (45cm in diameter, 0.33mm mesh open...
