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

Characteristics and Mechanisms of Spring Tidal Mixing and Sediment Transport in a Microtidal Funnel-Shaped Estuary

Journal of Marine Science and Engineering
Information about estuarine mixing and its control of sediment transport is crucial to elucidating the dynamics and evolution of estuaries. Here, the microtidal and funnel-shaped Zhenhai Estuary, located in the southwestern Pearl River Delta of China, is

Footholds for pioneers: How geomorphic features accelerate early marsh assembly

Limnology and Oceanography, Volume 71, Issue 7, July 2026.
Abstract Ecosystem transitions from bare to vegetated states often stall at early stages, before the biogeomorphic feedbacks needed for further expansion take hold. In aquatic systems, this bottleneck is especially common where inundation and hydrodynamic conditions may impose strong abiotic filters on pioneer establishment.

Use of SWOT Data for Hydrodynamic Modelling in a Tropical Microtidal Estuarine System: The Case of Casamance (Senegal)

Remote Sensing
Since the early 1990s, satellite altimetry has significantly improved our understanding of coastal and estuarine dynamics. The Casamance estuary in Senegal exemplifies a tropical microtidal system with limited instrumentation despite pressing ...

Adaptive Acoustic Monitoring for Endangered Cook Inlet Beluga Whales in Complex Soundscapes

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Effective conservation of the endangered Cook Inlet beluga whale (Delphinapterus leucas) requires comprehensive spatiotemporal data, yet monitoring efforts remain spatially biased, underrepresenting important southern habitats. Passive acoustic monitoring (PAM) provides the necessary broad‐scale coverage, but its expansion introduces ...

Global Fair‐Weather Bias in Remotely Sensed Coastal Suspended Sediment Concentration

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Satellite estimates of suspended‐sediment concentration (SSC) are widely used to understand ecosystem functions and resilience of coastal environments. Yet, they rely largely on fair‐weather observations. Combining continuous in situ time series with multi‐decadal satellite records and reanalysis products, we quantify a systematic fair‐weather

From Lotic to Lentic: SWOT Characterizes Seasonal Hydrodynamics in the Lake‐River Continuum

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The interface between rivers and lakes forms a unique hydraulic continuum, in which lotic and lentic regimes dynamically interact and transition between each other. A common expression of this lake‐river continuum (LARIC) is reservoir backwater, where water surface gradually rises from the reservoir pool upstream to the free‐flowing river ...

3D hydrodynamics of a macro-tidal estuarine environment under wave and tide forcings

, 2023
International audienceThe sandy estuaries along the English Channel have been silting up for over 10 years. Former geoscientific studies, which assessed sediment stocks, showed that the sedimentary material came from the marine rather than the fluvial ...

Timescales of Ecological Processes, Settling, and Estuarine Transport to Create Estuarine Turbidity Maxima: An Application of the Peter–Parker Model

The estuarine exchange flow increases the longitudinal dispersion of passive tracers and trap sinking particles, potentially creating an estuarine turbidity maximum (ETM): a localized maximum of suspended particulate matter concentration in an estuary ...
