Method for Augmenting Side-Scan Sonar Seafloor Sediment Image Dataset Based on BCEL1-CBAM-INGAN

Journal of Imaging
In this paper, a method for augmenting samples of side-scan sonar seafloor sediment images based on CBAM-BCEL1-INGAN is proposed, aiming to address the difficulties in acquiring and labeling datasets, as well as the insufficient diversity and quantity of

Linking the Movement Behavior of the Laptev Sea Walrus to Sea Ice and Resource Dynamics

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The walrus subspecies inhabiting the Laptev Sea (Odobenus rosmarus divergens) remains one of the least studied walrus taxa and occurs in a region undergoing rapid environmental change driven by climate warming and increasing human activity. We conducted the first satellite telemetry study of walruses in this region, tracking 14 individuals ...

Characterizing Habitat Suitability of Long‐Finned Pilot Whales in a Key Conservation Region of the Southern Iberian Peninsula Using Satellite Tracking Data

Marine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT The waters surrounding the southern Iberian Peninsula are a key conservation area for the long‐finned pilot whale (Globicephala melas melas), particularly in the pelagic regions of the Strait of Gibraltar, the Alboran Sea, and the Gulf of Vera, where upwelling, complex bathymetry and frontal dynamics enhance productivity and prey availability,

The effects of bioturbation on porewater chemistry and early marine diagenesis: Evidence from a modern intertidal zone in Abu Dhabi, U.A.E.

Sedimentology, Volume 73, Issue 6, Page 2120-2142, October 2026.
ABSTRACT Early marine carbonate cements generally form in CaCO3‐supersaturated seawater at the seabed or shallow burial depths, resulting in syn‐sedimentary cemented firmgrounds and hardgrounds. The processes controlling early marine diagenesis are complex, particularly in coastal environments where geochemistry is influenced by different water sources

Rodingite‐Derived Melt as a Recipe for Ultra‐Calcic Magmas

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Rodingite is a high‐CaO rock formed by Ca‐rich fluid metasomatism on mafic protoliths. It typically occurs within serpentinite and represents an often‐overlooked constituent of the altered oceanic lithosphere that may be subducted into the mantle.

Classification of seafloor habitats using acoustic backscattering of multibeam echosounder systems [PDF]

, 2008
Recognition of the superior data and coverage from multibeam echosounder systems has been widespread and is increasing rapidly. These systems are currently the most advanced and efficient tool for remote observations and characterization of the seafloor.

Generation and Preservation of Submarine Terraces: Insights From Records Imprinted on the Topography of Dokdo Volcano

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Marine terraces archive sea‐level and tectonic history, yet their relationship to individual highstands remains contentious. While most studies focus on subaerial terraces in uplifting settings, submerged terraces in subsiding settings are less explored. We develop a 1‐D wave‐erosion model and apply it to Dokdo — a subsiding volcanic island in

Listening to Tsunami Waves Induced by Glacier Calving

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Processes at the ice–ocean interface play a central role in regulating the stability of marine‐terminating glaciers and ice sheets and drive ocean freshening and mixing. Iceberg calving—a mechanical loss of ice—generates ocean waves and promotes water‐mass exchange in glacierized bays.

Near‐Field Acoustic and Gravity Wave Modes in the Ionosphere Triggered by Ground Motion and Tsunami During the 2024 Mw7.4 Hualien Earthquake

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 18, 28 September 2026.
Abstract The interaction between the atmosphere and other components of the Earth system, such as the solid Earth and the oceans, remains an open and active area of research. In particular, the dynamic response of the ionosphere to forcing from below, such as earthquakes and tsunamis, is not yet fully understood.

Marine Functional Connectivity Contributes to Ecosystem Functioning Across Multiple Scales

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 9, September 2026.
ABSTRACT The passive transport and active movements of marine organisms between habitats and ecosystems, known as marine functional connectivity, play a critical role in the functioning of marine ecosystems. However, marine functional connectivity, particularly at large spatial scales, is often understudied, and consequently tends to be overlooked in ...
