Standardization of CPUE for walleye pollock in the Okhotsk Sea with inclusion of some environmental factors

open access: yesИзвестия ТИНРО, 2020
Catch of walleye pollock by Russia is the highest in the northern Okhotsk Sea where on average 0.94 million metric tons were caught annually in the period between 1962 and 2017, or around 24 % of the total yield of Russian fishery.

Sub‐Wavelength Seabed Stiffness Control of Seismic Amplitude Modulation in Seafloor DAS

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Submarine distributed acoustic sensing cables record seafloor strain with striking spatial variability whose physical origin is not immediately obvious. By explicitly partitioning the recorded wavefield into ocean‐wave, Scholte‐wave, and teleseismic Rayleigh‐wave components, we show that these amplitude variations are not random but encode ...

Migration behavior for sockeye salmon adults of early race in the tributaries of Lake Nachikinskoye (western Kamchatka)

open access: yesИзвестия ТИНРО
Several stages are determined in the early run of sockeye salmon into tributaries of Lake Nachikinskoye: i) maturation of adults at depth, ii) concentration of adults in the mouths of the main tributaries, iii) entry of small flocks of the spawners into ...

EP‐ENSO Transition Facilitated the Kuroshio‐Oyashio Extension SST Anomalies to Reverse in Early and Late Autumn

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Kuroshio‐Oyashio extension sea surface temperature (SSTKOE) anomalies modulate local marine ecosystems and nearby climate extremes. Recent studies have preliminarily revealed that the SSTKOE anomalies reverse in early and late autumn, but its precursor drivers are still unclear.

Gold mineralization of the Median Massif, Kamchatka (Kamchatka Sredinnyi Massif)

open access: yesProceedings of higher educational establishments. Geology and Exploration, 2019
The gold mineralization of the Kamchatka median massif has been analyzed. It has been shown that within its lim-its, the ore mineralization of low-sulphide gold-quartz and gold-sulfide-quartz formations and also placers, formed on the base of this mineralization are widely developed.

open access: yes, 2006
A new species of the cottid genus Triglops Reinhardt is described on the basis of 21 specimens collected in Aniva Bay, southern Sakhalin Island, Russia, and off Kitami, on the northern coast of Hokkaido, Japan, at depths of 73–117 m.

Comparing Slab Viscous Dissipation Under Slab Distributed Weakening and Slab Segmentation Scenarios

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction of cold, dense oceanic lithosphere is a key driver of plate tectonics and mantle convection. However, how much gravitational potential energy is internally dissipated by slab deformation during subduction remains debated and largely depends on the mechanisms of slab weakening.
