Objectives of Cruise:
Our major objectives were to: (a) gain additonal information about upper-ocean
water properties and circulation relevant to fisheries; and (b) obtain
water property measurements over the eastern and central Bering Sea basin
to determine deep and bottom water circulation. The objectives in (b) were
met by making full-depth CTD casts, supplemented by sampling for silica,
CFCs, tritium and helium. Underway observation of surface temperature,
salinity, winds and currents (ADCP) were also carried out.
CTD casts: 94
CTD casts measured temperature, salinity and pressure from the surface
to near bottom (as great as 6800m). On most, but not all stations,12 to
24 samples were taken for analysis aboard of silica and freons (CFCs).
Samples were also taken for lab analysis of helium and tritium.
Underway ADCP data, surface temperature, salinity and wind data were
recorded throughout the entire cruise.
