New model for vortex-induced vibration of catenary riser [PDF]

, 2008
This paper presents a new theoretical model capable of predicting the vortex-induced vibration response of a steel catenary riser subject to a steady uniform current.

Sensitivity of Flood Extent and Population Exposure to Variations in Bathymetry Across a Shallow Continental Shelf Lagoon

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Bathymetry is a critical input to storm surge models on coastlines fronted by lagoon systems, yet few studies explore how variations in bathymetry influence flood impacts, flooded extent, and exposed population across these globally widespread morphologies.

Marine exploration [PDF]

, 2010
Less than 50 years ago knowledge of the geology of the UK continental shelf (UKCS) was extremely limited. The BGS marine geoscience programme began about 40 years ago in response to the development of the UK oil and gas industry. The BGS was funded by

Winter‐to‐Winter Sea Surface Temperature Anomaly Reemergence in the Yellow Sea

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract The reemergence of winter sea surface temperature anomalies (SSTAs) serves as an effective oceanic memory mechanism, linking winter SSTs across consecutive years in mid‐latitude deep oceans. However, its existence and potential role in modulating SSTA variability in continental shelf seas have remained largely unexplored.

Polyester Microfiber Dynamics in an Estuarine Semi‐Enclosed Basin

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Polyester microfibers are one of the most abundant microplastics in marine ecosystems, yet their observed near‐surface concentrations are inconsistent with expectations based on their density. To study the mechanisms governing polyester microfiber transport and fate, we developed a Lagrangian particle‐tracking module using Parcels to simulate ...

Dispersive Wave Focusing in Shoaling Water With Currents

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract A methodology creating dispersive focusing waves on constant depth, originally proposed by Rapp and Melville (1990), https://doi.org/10.1098/rsta.1990.0098, has provided a wide range of applications studying nonlinear waves, wave breaking, and rogue waves in the open ocean.

A Wave Tank Study on Turbulent Transport of a Passive Tracer Above Gravelly Sand Beds

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Exchange processes at the seabed interface have a non‐negligible impact on biogeochemical processes of the sea. Acknowledging this impact on the input of nutrients from the seabed into the water column further entails properly assessing the transport and mixing of these nutrients within the water column.

Double‐Peaked Hyperspectral Features at 710 and 800 nm for Monitoring Coastal Chlorophyll‐α Concentrations From Space

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract The concentration of chlorophyll‐α $\alpha $ has been estimated from sea color, primarily based on the reflectance ratio between the blue and green spectral bands in multiband images obtained by satellite optical sensors. However, this method is only effective in open, clear water and cannot be reliably applied to shallow coastal waters.

Influence of Biofilms and Extracellular Polymeric Substances on High‐Frequency Acoustic Backscatter

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Acoustic Backscatter Technique has been used to detect underwater targets and characterize seabed and river floor sediment properties. Microbial biofilms, consisting of microorganisms enclosed in Extracellular Polymeric Substances (EPS), have the potential to modify acoustic backscatter by altering the sediment topography, permeability, and ...
