Tracking Baseflow Supply Dynamics Using SWOT Data From Small Groundwater‐Dominated Lakes

Hydrological Processes, Volume 40, Issue 2, February 2026.
Satellite‐based measurements of groundwater flow‐through kettle lakes efficiently track dynamic groundwater storage at local to regional scales (modified from USGS Scientific Investigations Report 2011–5137). ABSTRACT In situ surface‐water monitoring strategies are biased towards larger perennial streams and lakes and are generally not designed to ...

Anaerobic oxidation of methane in the Concepcion Methane Seep Area, Chilean continental margin [PDF]

, 2012
Within subduction zones of active continental margins, large amounts of methane can be mobilized by dewatering processes and transported to the seafloor along migration pathways.

Microbial Diversity Across Chemolithotrophic and Phototrophic Biofilms in Cold Sulfur Springs

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Distinct microbial communities occur between adjacent sulfur‐rich and freshwater springs. Chemolithotrophic and phototrophic sulfur‐oxidizing taxa were enriched in cold sulfur spring biofilms, while adjacent freshwater biofilms supported more diverse microbial community composition.

Distribution and potential drivers of methane emissions from deep-sea environments in Haima cold seep areas

Frontiers in Marine Science
IntroductionTracing methane originating from deep-sea environments is essential for understanding the global methane budget. However, knowledge regarding the mechanisms governing methane transfer from deep-sea sediments to the water column in cold seep ...

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 ...

Stable Carbon Isotope Values of Bacteria‐Specific Fatty Acids to Assess the Reactivity of Sedimentary Organic Matter in the St. Lawrence Estuary and Gulf

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Coastal systems have seen increasing pressure from anthropogenic activities since the beginning of the century, affecting the health of these ecosystems. This increased pressure takes the form of an increase discharge of terrestrial organic matter (OM) and nutrients, leading to a higher primary productivity in the surface waters and to higher ...

Anaerobic oxidation of methane in hypersaline cold seep sediments [PDF]

, 2017
Life in hypersaline environments is typically limited by bioenergetic constraints. Microbial activity at the thermodynamic edge, such as the anaerobic oxidation of methane (AOM) coupled to sulphate reduction (SR), is thus unlikely to thrive in these ...

Plio‐Pleistocene Antarctic Bottom Water Production in the Ross Sea Reconstructed From Hillary Canyon Levee Turbidites

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Dense shelf water (DSW) formed on Antarctica's continental shelves is a significant precursor for Antarctic Bottom Water (AABW), a critical component of global overturning circulation. We hypothesize that DSW cascades off the central Ross Sea shelf generated density currents that entrained sediment as they flowed down Hillary Canyon, resulting

Magnesium geochemistry of authigenic carbonate at marine cold seep

Frontiers in Marine Science
Cold seeps, featured by their extremely methane-rich sedimentary environments, play a significant role in the geological history and are common in marine sediments across the seafloor.

Population genetic structure in Sabatieria (Nematoda) reveals intermediary gene flow and admixture between distant cold seeps from the Mediterranean Sea [PDF]

, 2017
BackgroundThere is a general lack of information on the dispersal and genetic structuring for populations of small-sized deep-water taxa, including free-living nematodes which inhabit and dominate the seafloor sediments.
