NUMERICAL STUDY OF THE M2 TIDE ON THE NORTH SIBERIAN SHELF

Abstract Modeling of the M 2 tide on the Siberian Arctic Shelf and adjacent continental slope is performed. The initial boundary-value problem for the equations in the form of contravariant fluxes is integrated on a non-uniform curvilinear grid. An M 2 tidal chart is given and interpreted. A tidal energetic balance and generalized energetic characteristics of the shelf and contiguous zone are presented.

SAR observations of internal waves in the Russian Arctic seas

In this work taking the advantage of high resolution spaceborne synthetic aperture radar (SAR) measurements we present first preliminary results of short-period internal waves (IW) observations in the Barents, Kara and White seas based on ENVISAT ASAR data for summer-autumn months in 2007-2011. Altogether more than 2000 IW packets were identified in about 1400 SAR images. Detailed maps of internal waves occurrences in the three Arctic seas have helped to identify main sites of regular IW generation.
