Hydrological studies of Zelenetskaya Bay in the summer of 2021

The thermohaline characteristics of the waters and the specificities of the hydrological regime of the Zelenetskaya Bay in the summer are analyzed. The location of the Bay, its relevance for scientific research and recreational use determine its importance as a model reservoir in the coast of East Murman (Kola Peninsula). The materials allow us to get an idea of the modern nuances of the hydrological regime of coastal waters. Over the past two decades, much less attention has been paid to such studies than to studies of the open part of the Barents Sea. The presented data of oceanographic observations were obtained in July 2021 during the expedition of the MMBI RAS to the R/V “Dalniye Zelentsy”. It is shown that in the studied area and in the Murmansk coast, in general, tidal currents play an important role in the formation of the thermohaline state of waters. Also important is the continental runoff, which has a desalinating effect locally in the lips of the peninsula. Additional information was obtained on the features of the distribution of desalinated water mass formed in the Zelenetskaya Bay and localized along the inner line of the islands.
