Abstract
Data on the generation of soliton-like internal waves by a mesoscale eddy in the region of the Barents Sea near Cape Svyatoi Nos, which is widely known for its dynamic activity, are presented. The results are based on analysis of satellite optical (Sentinel-2 MSI) and radar (Sentinel-1 SAR) images obtained sequentially on August 8 and 9, 2021. A detailed analysis of the dynamics of the eddy and internal waves was possible due to, among other things, the phytoplankton bloom, which created the necessary optical contrasts to enable monitoring of the dynamics of currents in the near-surface sea layer. The significant parameters of recorded internal waves were measured using satellite methods and were analyzed by means of the TPXO9.0 model and the numerical solution of the internal wave equation. It is shown that internal waves were caused by a submesoscale eddy formed near the cape. The waves have relatively low velocities (0.10–0.16 m/s), which is determined by the weak stratification of the water environment.
