The Abrupt and Persistent Decline in Recruitment Success in Northeast Arctic Cod: A Review of Probable Causes

Fish and Fisheries, Volume 27, Issue 3, Page 643-659, May 2026.
ABSTRACT Most of the previously large cod stocks in the North Atlantic are depleted to very low levels. A notable exception has been the Northeast Arctic cod inhabiting the Barents Sea. This cod stock reached a record high level around 2013, but since then has declined sharply, with older fish being fished out and few new recruits entering the stock ...

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

Fisheries Oceanography, Volume 35, Issue 3, Page 397-412, May 2026.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Al2O3 in Anorthositic Slabs: A New Perspective on LLSVPs and Seismic Velocity Variations

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aluminum is a key component of crustal and mantle minerals, influencing melting and geochemical evolution within the Earth. Al2O3 exists as corundum at the surface and in upper mantle conditions, but transforms into high‐pressure phases like Rh2O3(II) at lower mantle depths, enabling stability over a wide pressure range.

Uniformity in Heavy Precipitation Microphysics During the Northward Advancement of Summer Monsoon in China Unveiled by Objective Weather Typing

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The microphysical evolution of the East Asian summer monsoon precipitation during its northward advance across China remains unclear, due to the mixing of diverse weather systems in past studies. Applying objective synoptic classification to a decade of satellite observations, we isolate canonical monsoon‐type heavy precipitation across South,

Precursors of Marine Heatwaves in the Eastern Mediterranean

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Re‐analysis and observational data are used to identify the relationship between marine heatwaves and atmospheric heatwaves over the Eastern Mediterranean, and also the precursors of marine heatwaves in the 15‐day before heatwave onset. There has been a clear tendency for more heat extremes in recent years.
