Merging Recent Mean Sea Surface Into a 2023 Hybrid Model (From Scripps, DTU, CLS, and CNES)

Earth and Space Science
In this paper, we compute a new hybrid mean sea surface (MSS) model by merging three recent models, CNES_CLS22, SCRIPPS_CLS22, and DTU21, and taking advantage of their respective features.

SWOT‐Fitted River Bathymetry for Global Hydrodynamic Models

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We present a robust, global method to reconcile absolute water surface elevations (WSE) from the Surface Water and Ocean Topography (SWOT) mission with a large‐scale hydrodynamic model by iteratively correcting river bathymetry. After removing sensor and representativeness bias, we update riverbed elevations under DEM and min‐depth feasibility

Evaluating the sensitivity of raptors to wind turbine collisions: An integrative approach based on GPS tracking

Ecological Solutions and Evidence, Volume 7, Issue 4, October–December 2026.
Quantitative information on bird flight behaviour is essential to assess the sensitivity of different bird species to wind turbine collisions and inform wind turbine siting to minimise collision risk. By integrating (1) time spent in flight, (2) proportion of flights at risk height and (3) distance travelled from the nest location, derived from GPS ...

Synergy between in situ and altimetry data to observe and study Northern Current variations (NW Mediterranean Sea) [PDF]

Ocean Science, 2019
During the last 15 years, substantial progress has been achieved in altimetry data processing, now providing data with enough accuracy to illustrate the potential of these observations for coastal applications.

The downward legacy of a phytoplankton bloom in the oligotrophic North Pacific Subtropical Gyre

Limnology and Oceanography, Volume 71, Issue 10, October 2026.
Abstract Ocean particles are a heterogeneous collection, including living and dead cells, feces, mucus‐rich aggregates, and mineral shells and frustules. In the well‐lit upper ocean, phototrophic processes fuel production of particulate matter; however, only a relatively small percentage (< 10% per day) of this material (mostly detrital) escapes the ...

Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

Journal of Field Robotics, Volume 43, Issue 7, Page 4382-4401, October 2026.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

Spatial Altimetry and Continental Waters

, 2016
The transfer of energy and water, as well as gaseous components, in the soil–plant–atmosphere system plays a crucial role in many processes involved in climate change. The surface energy balance drives both evapotranspiration (closely linked to the CO2 flux) and sensible heat flux.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, Volume 34, Issue 6, Page 8018-8057, October 2026.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.
