Dynamic Migratory Strategies and Foraging Habitats of Southern Right Whales Revealed by Satellite Telemetry

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Satellite‐linked tags on 34 southern right whales revealed basin‐scale movements and foraging concentrated in the ACC, Crozet Islands, Benguela system, and the highly variable seasonal ice zone. Environmental modelling revealed environmental drivers behind foraging decisions, and identified key ecosystems.

From distant shores to an emerging island: the role of surface and subsurface transport in modeling seed dispersal

Ecography, Volume 2026, Issue 7, July 2026.
Long‐distance seed dispersal by ocean currents plays a critical role in structuring coastal plant communities. As direct observations of this phenomenon are infeasible, numerical modeling is a valuable tool. Here, we use Lagrangian particle tracking to examine the colonization of the newly forming island Norderoogsand (German Bight, Wadden Sea) by five

Improving Satellite-derived Bathymetry

, 2016
Bathymetry is traditionally acquired using singlebeam or multibeam echosounders. This method produces accurate depth measurements along transects but is constrained by operating cost and an inability to survey in very shallow waters. Airborne Lidar is able to produce accurate bathymetric information over clear waters at depths up to 70m, but can be ...

Revisiting the status of the Arctic's Last Ice Area as a refuge for marine predators

Ecosphere, Volume 17, Issue 7, July 2026.
Abstract The Last Ice Area (LIA), located north of the Canadian Arctic Archipelago and Greenland, has the Arctic's oldest and thickest sea ice. The LIA is hypothesized to be a potential climate refuge for ice‐dependent top predators as Arctic sea ice continues to decline.

Uncertainty Quantification of Analytical Solutions for the Nonlinear Space and Time Fractional Order ϕ4$$ {\phi}^4 $$ Equation Under Fuzziness

Engineering Reports, Volume 8, Issue 7, July 2026.
Analytical fuzzy soliton solutions of a modified space–time fractional ϕ4$$ {\phi}^4 $$ model are derived using EHFM, capturing memory effects and uncertainty. Results reveal diverse wave structures and show how fractional order and fuzziness significantly influence soliton amplitude, localization, and propagation, with heightened sensitivity near the ...

Permanent nearshore sediment loss and inevitable retreat of cohesive bluff‐backed beaches

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Net volume in survey control areas at the dune‐backed beach (PB) and bluff‐backed beach (LD) is shown between surveys (‘interval’), where the first point is the difference between 2012 and 2020 JABLTCX LiDAR surveys. Cumulative totals are shown as square markers. Water levels during the same dates are shown in grey.

Holistic analysis of shoreline change and mudbank dynamics across the Guiana coastline

Earth Surface Processes and Landforms, Volume 51, Issue 7, July 2026.
Annual analysis of shoreline change across the entire Guiana coastline, northern South America, including quantification of the rate and nature of alongshore mudbank migration and cross‐shore mangrove establishment and loss was conducted. Identification of other key coastal landforms contributing to exceptional rates of shoreline change across the ...

Meander‐Bend Erosion Dynamics Along a Gravel‐Bed River: Insights From Short‐Term UAV Monitoring

River Research and Applications, Volume 42, Issue 6, Page 1223-1238, July 2026.
ABSTRACT Riverbank erosion is a natural process in meandering rivers that contributes to sediment supply and geomorphic diversity, yet it can threaten infrastructure and human activities within the floodplain. Recently, many studies have used high‐resolution remote sensing technologies to measure bank erosion, but they often focus on technical aspects ...
