A subregional shallow water bathymetry derivation method for coral reef using ICESat-2 and Sentinel-2 combined with sediment information

open access: yesInternational Journal of Applied Earth Observations and Geoinformation
The bathymetric data is of great significance to coral reef protection. Traditional measurement methods have low efficiency, high cost, and are easily affected by natural conditions.

Identifying the Extent of River‐Influenced Waters of the Transpolar Drift With In Situ Measurements of Dissolved Organic Matter Fluorescence and Seawater Density

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract The oceanic component of the Transpolar Drift (TPD) is a key component of Arctic Ocean surface circulation. However, our understanding of its spatial extent and influence on the underlying water column remains limited. This study leverages a unique high spatial resolution oceanographic transect from August 2022 (late summer), first to identify

Dynamic Earth System Response to Interacting Climate Forcing Factors Through the Penultimate Deglaciation and Last Interglacial

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract The Penultimate Deglaciation (PDG) saw warming from the Penultimate Glacial Maximum to the Last Interglacial (LIG). We present 18‐kyr transient simulations through the PDG into the LIG using a fully‐coupled three‐dimensional ocean‐atmosphere model forced with Paleoclimate Modeling Intercomparison Project Phase 4 transient boundary conditions ...

Global Primary and Secondary Microseism Multi‐Decade Geographic Variation, Secular Intensification, and Period Lengthening

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.

Multimodel Combination Bathymetry Inversion Approach Based on Geomorphic Segmentation in Coral Reef Habitats Using ICESat-2 and Multispectral Satellite Images

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Owing to the high spatial heterogeneity of substrate types and terrain, the present satellite-derived bathymetry (SDB) methods have low accuracy in deriving large-scale bathymetry in coral reef habitats. Taking 11 coral reefs of Xisha Islands (ocean area

Depth from Satellite Images: Depth Retrieval Using a Stereo and Radiative Transfer-Based Hybrid Method

open access: yesRemote Sensing, 2018
Satellite imagery is increasingly being used to provide estimates of bathymetry in near-coastal (shallow) areas of the planet, as a more cost-effective alternative to traditional methods.

Satellite Derived Bathymetry and Water Level Change in Beysehir Lake

open access: yesJournal of the Geological Society of India, 2023
Abstract Several factors, including water level, depth, water quality, biodiversity, and tourist activities, play a crucial role in the sustainability of lakes, and therefore require constant monitoring. This study aimed to examine the water level changes of Lake Beysehir between 2015 and 2020 and determine whether there was a difference

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.
