Última The straits of Gibraltar and Kara Gates: a comparison of internal tides ArchiMer Morozov, Eg; Parrilla-barrera, G; Velarde, Mg; Scherbinin, Ad. Moored current measurements, numerical model calculations, and satellite images from the straits of Gibraltar and Kara Gates are compared. The vertical internal displacements (double amplitudes) with a semidiurnal frequency are extremely large in both straits. The displacements are related to internal tidal waves over the sills. The energy of the internal tides is transferred to an internal bore and associated wave packets of short-period internal waves. Their surface manifestation can be seen on the satellite images. Numerical modeling shows that the outflowing current from the Mediterranean Sea to the Atlantic Ocean has a significant influence on internal tides. In the Kara Gates, the flow from the Barents Sea to Kara Sea has a similar influence. The...

Automated electron probe X-ray micro-analysis (EPXMA) was used to characterise 17,600 individual particles collected in the Kara Sea and in the estuary of the Yenisey River. Samples were obtained by filtering and centrifugation of particles in suspension and from bottom sediments. Multivariate techniques were used to reduce the enormous data sets. By testing hierarchical, non-hierarchical and fuzzy clustering on the centrifuged suspension samples, it was shown that hierarchical clustering is most suitable. The two other clustering methods are very time consuming and in most cases do not add any additional information. This hierarchical clustering of the data matrix results in different particle types which can be apportioned to their possible sources. The...
