The primary objective of this research program was to understand the spatial and temporal behavior of the finestructure in the upper ocean of the marginal ice zone and, in particular, to determine the role that internal waves play in determining the behavior of that finestructure. A secondary objective was to provide high quality temperature and salinity profiles from the surface to the bottom in order to supplement the general hydrography of the region and to provide calibration data for other investigators. Analysis of the CTD times series data revealed that internal wave energy levels in the marginal ice zone are only slightly lower than those in the open ocean. We also showed that in the marginal ice zone intrusions make temperature spectra an invalid method for determining internal wave activity.
