A half century of monitoring reveals contrasting survival responses of Icelandic seabirds to climate and fisheries pressures

Ibis, Volume 168, Issue 3, Page 950-971, July 2026.
Seabirds serve as key indicators of marine environmental changes, with adult survival being a critical parameter for assessing population health. Iceland hosts some of the largest seabird populations in the North Atlantic, making it a valuable location for studying long‐term trends in seabird demographics.

Windblown Diatoms for Reconstructing Westerly Wind Variability in the South Atlantic Sector of the Southern Ocean

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Southern Hemisphere westerly winds are important drivers of Antarctic and sub‐Antarctic environmental change. Short observational wind records prevent us from fully understanding the scope of their variability. Proxy records provide valuable tools to extend environmental records. Here we present a novel wind study based on the use of windblown

Asymmetric Ocean‐Atmosphere Coupling Between Southeast Pacific and Southern Ocean Cooling Through Circulation and Sea‐Ice Changes

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Recent decades have seen persistent sea surface temperature (SST) cooling in the Southeast Pacific (SEP) and Southern Ocean (SO), contrasting with broad ocean warming expected under anthropogenic forcing. Using an interpretable machine‐learning attribution framework applied to multi‐source observations and reanalyses, we focus on monthly SST ...

Anthropogenic Carbon Isotope Signals in North Atlantic Water Masses at 48°N

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Deep‐water masses are formed in the North‐Atlantic, making studies of δ13C of dissolved CO2 in this region key to monitor and understand the spreading of anthropogenic carbon into the ocean interior. The objective of this study is to quantify the Suess effect (SE) in North Atlantic water masses using sulfur hexafluoride (SF6) as the ...

Wind‐Front Interactions Drive Intense Turbulence at the Oceanic Submesoscale

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Observations of the cold wake of Cyclone Biparjoy in the Arabian Sea reveal an asymmetrical boundary layer structure across a dense water filament (DWF). This asymmetry arises from the interaction between monsoonal winds and uniquely strong frontal buoyancy gradients.
