Zooplankton collections from the high polar basin with special reference to the Copepoda. Limnology and Oceanography
Analysis was made of 57 plankton tows taken to depths of 2,000 m from Sl”14 ’ N, 85”16 ’ N during a portion of the 1957-58 drift of the ice flow Drift Station Alpha in the high Polar Basin. Thirty-one species of Calanoid and 3 spccics of cyclopoid copepods were identified. Some uncertain species are...

| Summary: | Analysis was made of 57 plankton tows taken to depths of 2,000 m from Sl”14 ’ N, 85”16 ’ N during a portion of the 1957-58 drift of the ice flow Drift Station Alpha in the high Polar Basin. Thirty-one species of Calanoid and 3 spccics of cyclopoid copepods were identified. Some uncertain species are discussed and figured. The most abundant species were Calanus &cinlis, Calanus hyperboreus, and Metridiu Zonga. These wcrc most abundant above 100 to 200 m but were found spar&y distributed to depths of 1,000 to 2,000 m. Thcrc was an increased number of species with depth of sampling up to about 1,000 to 1,500 m. There appcarcd to bc a rather wide period over which reproduction takes place in some species cspccially Pareuchaeta glacialis. Although most copepods carried by water currents from the Bering Sea and Chukchi Sea areas succumb before reaching the high Arctic, still a Few cxpatriatcs were taken, notably Eucalanus bungii bungii and possibly Mimocalanus distinctocephnlus. |
