Plain Language Summary The polar regions are responsible for the formation of deep and bottom waters in the ocean, which account for a significant portion of its volume. The motion of these cold and dense waters is vital for oceanic heat transfer and has a direct impact on the Earth's climate. These deep flows also control sedimentation processes a...

Abyssal channels are the key points controlling bottom circulation of the World Ocean. They provide meridional transport of the coldest Antarctic Bottom Water between deep-water basins influencing the meridional overturning circulation and the climate on a global scale. Here we show that the synoptic variability of deep-water flows including blocki...

A powerful earthquake struck southeastern Turkey on 6 February 2023 with magnitude Mw = 7.8, followed by a second earthquake Mw = 7.5 just nine hours later. In addition, a storm surge caused by the passage of a cyclone over the area coincided with the first earthquake. Field observations showed that the fault planes did not extend to the Mediterran...

Данное исследование посвящено экстремальным колебаниям уровня моря, полученным с мареографов на побережье Японского моря во время прохождения тайфунов Майсак и Хайшен в сентябре 2020 года. Основное внимание уделено штормовым нагонам, сейшам и инфрагравитационным волнам (ИГ-волнам), выделенным из временны́х рядов на основе гармонического и статистич...

We analyze internal waves based on measurements on cruise 87 of the R/V Akademik Mstislav Keldysh in the Bransfield Strait near Half Moon Island and calculations using a numerical model. The measurements were carried out on January 25, 2022 for four hours using a line of temperature and pressure sensors, along with the measurements with a CTD probe...

Oceanographic data from measurements in deep-water channels of the Atlantic Ocean were analyzed. Data from two different methods were compared: CTD/LADCP measurements from research vessels and data from autonomous mooring stations. The comparison showed that discrepancies between the data obtained by two different methods can significantly exceed t...

Two powerful earthquakes struck southeastern Turkey on 6 February 2023 with the magnitudes of M w = 7.8 and M w = 7.5 in nine hours. In addition, a storm surge caused by the passage of a cyclone over the area coincided with the first earthquake. Field observations showed that the fault planes did not extend to the Mediterranean Sea; however, a weak...

Three-dimensional structure of currents in the Bransfield Strait (BS) was measured in 2017 over 50 transects across the strait using a Shipborne Acoustic Current Doppler Profiler (SADCP) onboard the R/V Akademik Sergey Vavilov and Akademik Ioffe. These data were used to determine local features of the three-dimensional velocity field of the current...

Strong acceleration of abyssal flows in narrow deep‐water channels and fracture zones is a key feature of bottom circulation in the Atlantic Ocean. In the Equatorial Atlantic, these bottom currents transport Antarctic Bottom Water (AABW) over the Mid‐Atlantic Ridge from west to east. The main pathway for Antarctic waters in this region is the Roman...

The Bransfield Strait is a relatively deep and narrow channel between the South Shetland Islands and the Antarctic Peninsula contributing to the water transport between the Pacific and Atlantic sectors of the Southern Ocean. The strait can be divided into three deep separate basins, namely, the western, central, and eastern basins. The sources of d...

The features of extreme sea level variations in the Russian Arctic under the conditions of global climate change have been studied in detail. Estimates of the rate of mean sea level rise in the Arctic are obtained from the monthly mean sea level data at coastal tide gauges and satellite altimetry. It was found that for the Arctic Ocean coast from t...
