Hydrological and Hydrochemical Research of the Mouths of the Small Rivers Flowing to the White Sea in the Winter Low-Water Season of 2019

Resumo

In the winter low-water season in March and the first week of April 2019, comprehensive hydrological and hydrochemical studies were carried out at the mouths of two small rivers of the White Sea catchment basin: (the Mudyuga River, which flows into Dvina Bay, and the Tamitsa River, which flows into Onega Bay). In the nearshore of the first river, microtidal conditions are observed (the size of the spring tide in summer is about 1 m); in the nearshore of the second river, mesotidal conditions are observed (the size of the spring tide in summer is 2.4 m).
