Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

Wildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

Past and Future Changes in Sea Ice in the Sea of Okhotsk: Analysis Using the Future Ocean Regional Projection Dataset

Journal of Marine Science and Engineering
Although subject to annual fluctuations, sea ice in the Sea of Okhotsk has decreased to a maximum extent at a rate of approximately 3.4% per decade since the 1970s. Thus far, few studies have focused on projections of sea ice in the Sea of Okhotsk.

PLUTONIC STRUCTURE OF THE DEEP-SEA BASINS IN THE SEA OF OKHOTSK REGION

Геодинамика и тектонофизика, 2018
The original continental crust of the deep-sea basins in the Sea of Okhotsk region was considerably reworked by tectonic and magmatic processes, whereby it has become substantially denser while less thick.

Contrasting population genetic structures of congeneric coastal flounders associated with different early life histories

Journal of Fish Biology, EarlyView.
Abstract Marine fish species are likely to exhibit little genetic differentiation among populations due to their high dispersal potential during early life stages and migratory nature. However, recent studies have increasingly reported intraspecific genetic differentiation resulting from species‐specific ecological traits, environmental factors, and ...

The 2025 Kamchatka Earthquake and Tsunami: Cascading Impacts and Risks to Japan

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2837-2854, September 2026.
ABSTRACT On July 29th, 2025, a large earthquake (Mw 8.8) occurred near the Kamchatka Peninsula. This event caused a tsunami that reached Japan's Pacific coast, even though the source was far away. In this study, we analyze the characteristics of earthquakes and tsunamis and discuss how they relate to the recurrence possibility and risk in Japan.

Anomalous Sea Ice Retreat in the Refreezing Western Arctic by a 30‐Year Record Cyclone in October: Oceanic, Atmospheric, and Wave Influences

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract An extreme Arctic cyclone (AC) in October 2022 reached a record‐low pressure of 955 hPa and caused unusual wave‐induced sea‐ice breakup in the Canada Basin, making it the strongest event in the western Arctic in 30 years. Here we examine how this event interrupted freeze‐up by quantifying sea‐ice retreat associated with atmospheric and oceanic

Results of trawl counts for juvenile pink salmon in the Bering and Okhotsk Seas in 2024 and prospects for the returns and catch in the Karaginsky subzone and Okhotsk Sea in 2025

Известия ТИНРО
The key stage of juvenile pink salmon monitoring is the survey of their fall feeding in the sea that detects the year-class strength. The results of this survey are used for forecasting of the pink salmon returns to the Karaginsky fishing subzone in ...

Low ocean-floor rises regulate subpolar sea surface temperature by forming baroclinic jets

Nature Communications, 2018
Sea surface temperature fronts in mid-and-high latitudes give significant impacts on atmospheric circulations and climate. Here, the authors uncover a new mechanism on the sea surface front genesis in the subpolar oceans in which small-amplitude bottom ...
