The active emission of gas (mainly methane) from terrestrial and subsea permafrost in the
Russian Arctic has been confirmed by ample evidence. In this paper, a generalization and …

The Russian sector of the arctic shelf is the longest in the world. Quite a lot of places of
massive discharge of bubble methane from the seabed into the water column and further …

The summer heat wave in 2018 led to the highest recorded water temperatures since 1926–
up to 21° C–in bottom coastal waters of the Baltic Sea, with implications for the respiration …

Baltic Sea bathymetric properties are analysed here using the newly released digital
bathymetric model (DBM) by the European Marine Observation and Data Network …

The paper presents the results of in situ studies of marine particles of different nature using a
submersible digital holographic camera (DHC) during the Arctic expedition. It also describes …

We validate a new model for mass transfer and bubble transport for natural seeps on the
continental margins using an integrated observation of a seep at 883 m in the Northern Gulf …

Carbon capture and storage (CCS) could significantly contribute to reducing greenhouse
gas emissions and reaching international climate goals. In this process, CO2 is captured …

The highest concentration of cold seep sites worldwide has been observed along
convergent margins, where fluid migration through sedimentary sequences is enhanced by …

Seeps found offshore in the East Siberian Arctic Shelf may mark zones of degrading subsea
permafrost and related destabilization of gas hydrates. Sonar surveys provide an effective …

Reliable quantification of natural and anthropogenic gas release (eg CO 2, methane) from
the seafloor into the water column, and potentially to the atmosphere, is a challenging task …
