Tracing methane sources in shallow waters of the North Sea: Biogenic signatures and hydrocarbon transport near abandoned wells

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Numerous abandoned wells in the North Sea may provide gas, particularly methane (CH4), migration pathways by penetrating shallow, biogenic gas accumulations. However, related sampling campaigns have been largely contradictory and lack a substantial database. Research cruise MSM98 targeted the abandoned wells B18‐1, DOK 1‐X, B11‐2, THOR and D‐1

Seasonal Estimates of Nutrient Loading, Sources, and Impacts on Water Availability in Streams Across the Conterminous United States, 2000–2020

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Excess riverine nutrients can limit water availability for humans and ecosystems. Nutrient monitoring on individual stream reaches provides important information about current and past conditions, yet most river reaches are unmonitored. Additionally, monitored data integrate effects of upstream sources, sinks, and pathways by which nutrients ...

Experiment and Numerical Simulation of Seawater Intrusion under the Influences of Tidal Fluctuation and Groundwater Exploitation in Coastal Multilayered Aquifers

Geofluids, 2019
The dynamic behavior of groundwater flow and salt transport is affected by tide and pumping in coastal multilayered aquifers. In this paper, two groups of experiments were conducted considering different constant head inland boundaries.

An Emergent Seafood Nationalism Takes Hold in the United States

Fish and Fisheries, Volume 27, Issue 4, Page 1047-1055, July 2026.
ABSTRACT This paper introduces the concept of ‘seafood nationalism’ to describe how, since 2024–2025, the United States increasingly uses tariffs, trade remedies, food safety enforcement and origin‐based rules to favour American seafood over foreign products.

Habitat Suitability for a Unique, Fully Marine American Manatee (Trichechus manatus) Population Primarily Depends on Presence of Submarine Freshwater Springs

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The American manatee (Trichechus manatus) requires freshwater mainly from rivers and springs to maintain osmoregulatory balance in saline environments. However, in Brazil's semi‐arid Potiguar Basin, manatees now rely solely on submarine freshwater springs because hypersaline estuaries have become unsuitable sources of freshwater.

Evaluation of saline water intrusion along the coastal aquifers of Vadakara, Kerala, South India, using hydro geochemistry and GIS

Journal of Degraded and Mining Lands Management
The hydrogeochemical characteristics and evaluation of saline water intrusion of shallow groundwater in the coastal aquifers of Vadakara have been investigated using geochemical analysis and spatial interpolation techniques.

The Global Contribution of Individual Submarine Groundwater Discharge Components to the Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Saline submarine groundwater discharge (SSGD) contributes to ocean chemistry through water‐rock interactions as seawater circulates in coastal aquifers. Its components, driven by different mechanisms, exhibit varying residence times and degrees of chemical alteration, so constraining solute fluxes requires quantifying each component.
