Overflow '60 was an ICES investigation of cold, sub-arctic, deep
water overspill into the North Atlantic Ocean from the Iceland-Faroe
Ridge. It was desigend as a corollary to the Polar Front Survey
investigations of the International Geophysical Year, and was carried
out from 30 May to 18 June 1960, under the leadership of Dr J. B. Tait.
Overflow '60 was an optimal coordination of 9 research ships in a
small region to reach a maximum of synoptic work. It was also an
optimal intensification of measurements with the same methods, and it
was generally regarded as the starting point of current measurements in
deep water by self-recording anchored instruments. A complete overview
of the results of this expedition have been published by ICES in
Rapports et Proces-Verbaux des Reunions, Vol 157. This may be purchased from ICES.
