Weddell Sea. At the Stations in the "oldest" type of Weddell Sea water (o-i-o° C.) east of South Georgia (Sts. 779, 797, 798, 799, 806), at which the catch was in the lower nets, it seems reasonable to assume that the Rhincalanus population originated from the South Atlantic and had been carried into water from the Weddell Sea by southward-moving warm deep water. At Sts. 795, 804, and perhaps 807, in Weddell Sea water carrying melting pack-ice, the origin of at least a part of the population is no doubt the same, and.
