Microeukaryotic Diversity and Habitat Structuring in a Desiccating Alkaline Maar Lake (Central Mexico)

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Microeukaryotes are important components of microbial food webs in saline and alkaline lakes, yet their diversity and distribution across distinct microhabitats remain poorly understood. We characterized microeukaryotic communities associated with microbialites, microbial mats, hypersaline waters, and sediments in the desiccating maar lake ...

Spatial Diversity of Marine Protists Along the Northern Norway Fjords During the Sub‐Arctic Summer

Journal of Eukaryotic Microbiology, Volume 73, Issue 6, November/December 2026.
ABSTRACT Polar coastal waters are highly complex and productive ecosystems that experience increasingly higher average water temperatures, shallower and stronger stratification, and higher glacier‐melting rates. Yet, the environmental complexity and high microbial diversity within fjords pose challenges to understanding the impacts of these changes and

Net Carbon Transfer From Ocean to Land During the Last Deglaciation Synchronous With Sea Level Rise and Lagging Atmospheric CO2 by Several Millennia

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The sequence of events in the global carbon cycle during deglaciations is not entirely understood. Here, we analyze mean ocean δ13 ${\delta }^{13}$C and δ18 ${\delta }^{18}$O in an updated compilation of foraminiferal stable isotope data comprising 902 time series from 381 sediment cores, with individual records covering intervals within the ...

Enhancement of the Nighttime Ocean Cool Skin Effect by Natural Surfactants

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The ocean interface brightness temperature is sensitive to the biologic activity reflected by the chlorophyll‐a concentration (Chla) in the upper layers of the oceans. This is shown using sea surface skin temperatures Tskin retrieved from spectra recorded by the Infrared Atmospheric Sounder Interferometer and collocated measurements of bulk ...

Reassessing Methanesulfonic Acid as a Sea Ice Proxy: An Example From the Weddell Sea Sector

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Antarctic sea ice has declined since 2015, but placing this trend in a longer‐term context remains challenging. Ice core methanesulfonic acid (MSA) offers a potential record of sea ice variability beyond the instrumental period, yet its applicability in sectors including the Weddell Sea remains unclear.

Diagnosing the Influence of Southern Ocean Storms on Air‐Sea Carbon Dioxide Flux From Synthetic Floats: A Modeling Study

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The Southern Ocean is the stormiest place on Earth, but sparse observations challenge our ability to understand the influence of storms on air‐sea CO2 $\mathrm{C}{\mathrm{O}}_{\mathrm{2}}$ fluxes. Here we quantify storm‐driven Southern Ocean CO2 $\mathrm{C}{\mathrm{O}}_{\mathrm{2}}$ fluxes using synthetic floats that mimic real‐world platforms

Isopycnal Pathway for Small‐Particle Export in a Decaying Cyclonic Eddy Revealed by a BGC‐Argo Float

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mesoscale eddies influence carbon export through production, subduction, mixing, and particle redistribution. In this study, a BGC‐Argo float observed a deep particle layer in the twilight zone during the decay of a cyclonic eddy in the Northwest Pacific.

Asymmetric Particle Aggregation in Ocean Eddies Driven by Eddy‐Wind Interactions

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Mesoscale eddies, prevalent across the global ocean, play a crucial role in the transport and mixing of climate‐sensitive tracers such as heat, salt, and nutrients. While traditional quasi‐geostrophic theory predicts symmetric kinematics and equivalent material transport by cyclonic and anticyclonic eddies, our analysis of satellite altimeter ...

Through the Cracks: Sea Ice Regions as a Source of Volatile Marine Sulfur in the Springtime Arctic

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Marine volatile methylated sulfur compounds (VMS) including dimethyl sulfide (DMS) and methanethiol (MeSH), are important natural sources of sulfur to the atmosphere and precursors to aerosols and cloud condensation nuclei. However, observations of DMS and MeSH in regions with sea ice remain limited.

Aerosol Retrieval Over Ocean From DPC‐2/GF‐5(02): Using RemoTAP Extended With a 3‐Parameter Ocean Bio‐Optical Model and Comparisons With a 1‐Parameter Model

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 20, 28 October 2026.
Abstract Multi‐angle polarimetric instruments (MAPs) enable the retrieval of essential aerosol properties over oceanic regions. MAPs retrieval algorithms commonly use a 1‐parameter ocean bio‐optical model (OBM), based on chlorophyll‐a concentration only to represent optical properties over open waters (case‐1), whereas the coastal water (mixture of ...
