J. H. Fraser’s research while affiliated with Plymouth Marine Laboratory and other places

Through the kindness of Dr L. H. N. Cooper of Plymouth I have been given the opportunity of examining some of the plankton samples taken by Surg.-Lt. P. Campbell, R.N.V.R., of H.M.S. Challenger. It is hoped that the results of these and later surveys will be published elsewhere in more detail, and in association with those made by the Scottish research vessels farther north, but two records of unusual interest are brought to notice here. The collections so far examined in detail were taken during April and May 1953, on a line of stations west of the English Channel, from 49 N., 3 W. to 47 N., 17 W. between 15 and 19 April, and on the return line from 47 N., 17 W. to 49 N., 5 W. between 25 and 28 May. They were made by 10 min. horizontal hauls at 30 fathoms depth.
