Artic Mixed Layer Dynamics.
Abstract
Contents: Seasonal Variations in the Upper Artic Ocean as Observed at T-3: Hydrographic data from T-3 are analyzed to illustrate the behavior of the Artic mixed layer. The mixed layer depth fluctuates 11 m annually and mixed layer salinity fluctuates 0.32% ppt. The fluctuations in total salt content are consistent with theoretical work by Maykut and are in phase with mixed layer depth, indicating changes in the mixed layer are controlled by salt flux. Oceanographic Conditions in the Marginal Ice Zone North of Svalbard in Early Fall 1979 with an Emphasis on Mesoscale Processes: During September-October 1979 the Norwegian Remote Sensing Experiment was carried out in the marginal ice zone north of Svalbard. Convergence of the ice cover is correlated with along-ice edge winds with the ice to the right, while divergence occurs during off-ice winds or calm conditions. The Fram 3 Expedition: On the fourteenth of March 1981, Fram 3 the third in a series of four U.S. manned ice camps, was established in the eastern Arctic Ocean at 84.32 N, 20.07 E for studies of physical and chemical oceanography, low-frequency underwater acoustics, geophysics, and the mechanics and propagation of waves through sea ice. Salargos Temperature-Conductivity Buoys: The design and testing of buoys capable of measuring temperature and salinity in ice covered oceans is described. The buoys are implanted in the sea ice and collect water temperature and conductivity data from pairs of sensors tethered to a cable suspended below the ice. The sensor data is collected and position is determined using the ARGOS satellite system.
