A brief, non-detailed description is given of an automatic, multiple net plankton sampler used on a submarine cruise between the North Atlantic and Pacific oceans by way of the North Pole. The copepods contained in 90 samples from the Arctic have been identified and their relative abundance determined. The most frequently and widely occurring of the 18 species were Metridia longa, Calanus hyperboreus and C. glacialis. Pseudocalanus minutus, found mostly in the Chukchi Sea region, was the most abundant. From their known geographic distribution, six species are recognized as cosmopolites and 12 as Arctic or cold water species. Of the latter group, one is endemic to the Arctic and five are not known from the Pacific.
