Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.

Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Seasonal and Diurnal Patterns of Harbor Porpoise (Phocoena phocoena) Behavior and the Disruptive Effects of Vessel Presence in a High‐Traffic Coastal Habitat

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Chronic anthropogenic activity is an ongoing threat to the marine environment and presents unique challenges in shallow, coastal habitats where harbor porpoises reside. Harbor porpoises have high metabolic needs and are highly susceptible to negative environmental factors; however, no long‐term studies have been conducted on wild populations ...

Unveiling Patterns in Cetacean Strandings Along Southern Atlantic Iberia: Temporal and Spatial Trends, Seasonality, and Causes of Death

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT We compiled 46 years of cetacean strandings in the Algarve, Portugal, describing temporal–spatial patterns, size–sex structure, and causes of death (COD). We analyzed national records and years with a dedicated regional stranding network (SN) to assess annual/seasonal trends, spatial hotspots, and compare biometrics and COD.

Estimated tissue and blood N2 levels and risk of in vivo bubble formation in deep-, intermediate- and shallow diving toothed whales during exposure to naval sonar

Frontiers in Physiology, 2012
Naval sonar has been accused of causing whale stranding by a mechanism which involves formation of tissue N2 gas bubbles. Increased tissue and blood N2 levels, and thereby increased decompression sickness (DCS) risk, is thought to result from changes in ...

Navigating the Ethereal Tightrope: The Nanogenerator Manipulates Neurons for Immune Equilibrium

Advanced Science, Volume 13, Issue 14, 9 March 2026.
This review explores how nanogenerators modulate neuroimmune responses, offering innovative strategies for treating neurological disorders. By interfacing with neural pathways, they enable precise control of immune activity, especially via vagus nerve stimulation.

High-Resolution Sonars: What Resolution Do We Need for Target Recognition?

EURASIP Journal on Advances in Signal Processing, 2010
Target recognition in sonar imagery has long been an active research area in the maritime domain, especially in the mine-counter measure context. Recently it has received even more attention as new sensors with increased resolution have been developed ...

Holocene subaqueous landslide dynamics in the Lake Siljan‐Orsasjön Basin, south‐central Sweden

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Subaqueous landslide areas studied by multibeam bathymetry, sub‐bottom profiling and sediment coring reveal complex stratigraphies, suggesting mass movement events starting close to the area's deglaciation and up to very recent times. Abstract The Siljan‐Orsasjön Basin in south‐central Sweden hosts two prominent lakes.
