Shallow Water Bathymetry Mapping from UAV Imagery based on Machine Learning [PDF]

, 2019
The determination of accurate bathymetric information is a key element for near offshore activities, hydrological studies such as coastal engineering applications, sedimentary processes, hydrographic surveying as well as archaeological mapping and ...

Multidecadal Oscillation Masks Ocean Wave Climate Trends in 75‐Year Global Wave Hindcast

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The observed increases in temperature and sea level are clearly driven by climate change, and these trends are projected to accelerate in the future. The ocean surface wave characteristics are projected to change depending on the climatic elements.

Spectral characterization of the Nigerian shoreline using Landsat imagery [PDF]

, 2013
The challenges of shoreline mapping include the high costs of acquiring up-to-date survey data over the coastal area. As a result, in many developing countries, the shoreline has not been consistently mapped.

Impact of Intraseasonal Coastal Trapped Waves on Upwelling in the Northern Gulf of Guinea

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract We investigate the impact of equatorially‐forced intraseasonal coastal trapped waves (CTWs) on temperature variability in the Northern Gulf of Guinea (NGG) upwelling system, using a high‐resolution (1/36°) regional ocean model simulation spanning 2008–2017.

Wind‐Induced Coastal Upwelling Off Southeast Japan Supplying Surface Nutrients to the Kuroshio Downstream

Journal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Wind‐induced coastal upwelling plays a significant role in ocean circulations and ecosystems. Although coastal upwelling along eastern boundaries by trade winds is well known, coastal upwelling along western boundaries and its effects in the North‐East Pacific Ocean have not been well investigated in previous studies.

Were There Tides on Ancient Mars?

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Tides are a key component in the Earth system as they help regulate climate and sustain life. Mars very likely had a surface ocean around 4–3 billion years ago. The NASA Curiosity Rover and the CNSA Zhurong Rover were sent to Gale Crater and the Vastitas Borealis Formation (VBF) on Mars to explore the surface and search for evidence of the ...

Modeling Wind‐Driven Waves on Other Planets: Applications to Mars, Titan, and Exoplanets

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.
Abstract Waves could exist on any planet with sustained winds and stable surface liquids. However, differences in atmospheres, liquids, and gravity confound efforts to extend Earth‐based empirical wave models to other planetary environments. We adapted a physics‐based numerical wave model to study how planetary conditions affect the growth of waves. We

Study of the time evolution of the lithosphere [PDF]

The behavior and mechanical properties of the lithosphere were studied. This is a prerequisite to an understanding of the mechanisms and processes that occur in the Earth's mantle, which are masked by the lithospere. Geoid heights derived from the GEOS-3

Modeling Upper Ocean Ecosystem Dynamics in Response to Interannual Sea‐Ice Variability in the Western Antarctic Peninsula

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract In the Western Antarctic Peninsula (WAP), marine plankton dynamics are tightly linked to the interannual variability in environmental conditions, including phenological shifts in sea‐ice seasonality. To explore these linkages, we use a 1‐dimensional vertical ocean‐ice‐ecosystem model (KPP‐Eco‐Ice, or KEI) that simulates physical and ecosystem ...
