For more information see http://www.whoi.edu/page.do?pid=66623\n'While Soviet postwar activities in the Arctic were unknown to the west until 1954, the US Air Force began B-29 reconnaissance flights to the region beginning in 1946. Surprisingly, several large ice masses were spotted in the deep basin, which were later determined to be icebergs which had broken off and drifted from the ancient glacial ice foot of northern Ellsmere Island. By 1951, daily reconnaissance trips to the Pole were being implemented, and the drift of three large ice island targets (T-1, T-2, and T-3) were being tracked. The following year, the Alaska Air Command organized Project ICICLE in order to establish a weather station on one of the ice islands and conduct geophysical research. Joseph O. Fletcher was put in charge of the project, and ice island T-3 was selected as the site.'\n\nsee also Crary, A.P., Cotell, R.D., and T.F. Sexton, T.F. 1952.

Temperature, salinity and oxygen concentrations were measured at standard oceanographic depths with additional sampling to clarify the Pacific and Atlantic temperature maxima.","sampling":"Plankton tows were taken with three mesh sizes (Nos. 0, 6 and 20) and a variety of net diameters. However due to the large amount of material collected only part of the No.O mesh net series was included in the study. This net had a mouth diameter of one metre and a length of seventeen feet.\n\nClosing nets were not used during this study. Sampling depths were chosen to correlate the plankton with the different water layers. Tows of 50-0 metres\n(Arctic surface), 100-0 metres (which included summer Bering Sea water), 175-0 metres (which included winter Bering Sea water), 300-0 metres (which included Intermediate water), 900-0 metres (which included Atlantic water) and 2000-0 metres (which included Arctic deep water) were taken.\n\nThree unidentified species of copepods were collected and illustrated. One of these species was later described and named after the author.
