Rates of Sea‐Level Rise Are Highly Sensitive to Ice Viscosity Parameters in Model Benchmarks

AGU Advances, Volume 7, Issue 2, April 2026.
Abstract Glacier flow plays a major role in current and future rates of globally averaged sea‐level rise. The viscosity of glacial ice, controlling the rate of flow, decreases as stress increases and is highly sensitive to the value of the stress exponent, n $n$, in the constitutive equation for viscous flow.

Drivers of Benthic Iron Fluxes and the Pore‐Water Iron Isotopic Signature in Surface Sediments of South Georgia Fjords, Sub‐Antarctica

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Benthic iron (Fe) fluxes from coastal sediments support phytoplankton blooms downstream of subpolar islands. We combine solid‐phase and pore‐water geochemical data, including its iron isotopic signature (δ56Feaq), to identify the main drivers of benthic Fe fluxes from sub‐Antarctic fjord and shelf sediments of South Georgia, and to evaluate ...

Using Machine Learning to Uncover Ecological Mechanisms Controlling Abundance of Phytoplankton Size Classes From Large‐Scale Observations

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Phytoplankton size classes (PSCs) and Phytoplankton functional types (PFTs) determine many fundamental biogeochemical processes including nutrient uptake, energy transfer through marine food webs, ocean carbon export, and gas exchange with the atmosphere. Discerning the causes of spatio‐temporal variability of PSCs is a scientific priority for

Global Primary and Secondary Microseism Multi‐Decade Geographic Variation, Secular Intensification, and Period Lengthening

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.
