Three oceanographic surveys were conducted in the vicinity of the Grand Banks of Newfoundland in support of International Ice Patrol operations 1965. Measurements of temperature and salinity obtained from serial Nansen bottle observations were used to determine the dynamic topography, a principal factor in studying the most probable drift of icebergs endangering shipping in this area. A short check survey of one standard section was conducted during the season in order to detect any short term changes in the Labrador Current. Subsequent analysis of selected oceanographic sections was accomplished to calculate the volume flow and heat transport through these sections. In addition, an isentropic analysis was undertaken in order to make a comparison with the circulation deduced from the dynamic topography. A change in vertical sampling technique was attempted in order to define more accurately the maximum and ninimum points in the distribution of temperature and salinity. Studies of iceberg deterioration and specific drift factors were initiated during Ice Patrol 1964 and were continued during 1965 with some increase in emphasis. (Author)
