Comparing convolutional neural network and random forest for benthic habitat mapping in Apollo Marine Park

Remote Sensing in Ecology and Conservation, Volume 12, Issue 2, Page 275-291, April 2026.
A comparison of Convolutional Neural Network (CNN) and Random Forest (RF) model predictions of benthic habitats within Apollo Marine Park. The CNN (left) and RF (right) classification maps show the spatial distribution of three habitat types: high energy circalittoral rock with seabed‐covering sponges, low complexity circalittoral rock with non‐crowded

Atmospheric Teleconnections as Potential Drivers of Ross Ice Shelf Basal Melt

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Understanding the processes that regulate basal melt variability beneath Antarctic cold‐cavity ice shelves remains a key challenge for constraining future ice‐sheet mass loss. By linking melt variability directly to the mixing ratios of water masses entering the ice‐shelf cavity over 1993–2018, Pochini et al.

Bifurcation Analysis of a Resource–Consumer System With Explicit Spatiotemporal Memory

Studies in Applied Mathematics, Volume 156, Issue 4, April 2026.
ABSTRACT In ecological systems, animal movement is often influenced by memory and spatial cognition, especially in advanced species. This paper investigates the dynamics of a diffusive resource–consumer model incorporating explicit spatiotemporal distributed memory, where memory effects are modeled as distributed delays in both time and space.

Evaluating the possible role of bottom currents and internal waves in shaping seafloor morphology in a mesophotic reef

Sedimentology, Volume 73, Issue 3, Page 593-619, April 2026.
ABSTRACT Mesophotic reefs are located in low light conditions which, depending on the region, are usually found in water depths greater than ~30 m. They are less affected by ocean warming than reefs found in shallower water depths and thus might become increasingly important for the sustainability of marine biodiversity.

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

Sedimentology, Volume 73, Issue 3, Page 620-644, April 2026.
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.

P-AUV: Position aware routing and medium access for ad hoc AUV networks

Journal of Network and Computer Applications, 2019
Abstract Autonomous underwater vehicle (AUV) networks are used for coordinated missions such as area mapping and remote surveillance. AUVs are typically deployed by a central platform such as a ship or a submarine, and they operate in an unattended environment. Although there is no need for continuous monitoring of AUV nodes, the central platform may
