Insights Into the Influence of the Greenland Ice Sheet on Oceanic Macronutrient Dynamics From Decades of Historical Data

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract Increasing freshwater discharge from the cryosphere has the potential to affect mechanisms that regulate the supply of macronutrients to primary producers in the ocean. Although numerous studies have characterized the biogeochemical effects of freshwater discharge from the Greenland Ice Sheet within fjords, it is unclear to what extent these ...

Seasonality in Marine Organic Carbon Export and Sequestration Pathways

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The ocean's biological carbon pump transports organic carbon from the surface to depth via three main pathways: the gravitational sinking of particles, active transport by vertically migrating zooplankton, and mixing and advection of suspended and dissolved organic carbon.

Active Transport of Carbon to Demersal Fish Communities in Shelf‐Slope‐Abyssal Systems of the North Atlantic Ocean

Global Biogeochemical Cycles, Volume 40, Issue 2, February 2026.
Abstract The biological carbon pump sequesters carbon through passive fluxes of biologically derived carbon, and by active vertical movement of marine organisms. Trophic coupling between pelagic and benthic communities increases the efficiency of the biological carbon pump as less carbon is lost to remineralization.

Silicate and Carbonate Weathering Perturbation at the Eocene‐Oligocene Transition Recorded by Mg Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...

Eddy‐Induced Iron Transport Sustains the Biological Productivity in the Gulf of Alaska

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract The surface waters of the subarctic northeastern Pacific Ocean contain high concentrations of macronutrients such as phosphate and nitrate, which can potentially drive photosynthesis and biological uptake of carbon dioxide. Regional biological productivity, however, is limited by a lack of necessary micronutrients such as iron.

The Response of the Physical and Biogeochemical Marine Environment to the Passage of Mediterranean Cyclones in the Presence of Eddies, Gyres, and Marine Heat Wave

Journal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Medicanes, a class of the most intense Mediterranean cyclones, are known to have a substantial influence on the physical and biogeochemical properties of the marine environment. Yet, our understanding of how this response under various precyclone sea conditions is still lacking.
