Lake Morphometry Influences the Accuracy of SWOT Estimates of Water Level

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Lake water surface elevation (WSE) data in Sweden are needed to understand water supply and ecosystem services provision. SWOT can complement WSE in situ measurements, but the influence of lake shape on its accuracy remains unclear. We explore the performance of the SWOT pixel‐cloud and this influence across 62 lakes from August 2023 to ...

Adhesion‐Driven Removal of Microplastics From Aquatic Systems by Using Microgel Glues

Advanced Science, Volume 13, Issue 38, 9 July 2026.
Soft polymeric microgels function as “glues” that aggregate diverse microplastics through multivalent adhesion, promoting their interfacial deposition and co‐precipitation for efficient removal from water. Remarkably, this approach remains effective even for nanoscale plastic particles as small as 50 nm.

Improved Geoid Determination Based on the Shallow-Layer Method: A Case Study Using EGM08 and CRUST2.0 in the Xinjiang and Tibetan Regions

Terrestrial, Atmospheric and Oceanic Sciences, 2013
In this paper we present the concepts and realization of the shallow-layer Shen geoid determination method, which is quite different from the classical geoid modeling methods (Stokes¡¦ method, Molodenskii¡¦s method, etc.), for determining the global or ...

Topographic Effects in Geoid Determinations

Geosciences, 2018
Traditionally, geoid determination is applied by Stokes’ formula with gravity anomalies after removal of the attraction of the topography by a simple or refined Bouguer correction, and restoration of topography by the primary indirect topographic ...

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.

Impact of datum transformation on local variations of geometric geoid in Niger

Geodesy and Cartography, 2017
In this study, we have conducted an investigation on the impact of the coordinates’ transformation on local variations of geometric geoid. The study area is limited by 1°43′12″ to 4°00′37″ East and 13°01′57″ to 14°31′20″ North in the southwest of the ...

Geophysical Investigation of Geothermal Potential in Southern Thailand: Insights From GGMplus Gravity

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Southern Thailand hosts numerous low‐ to medium‐enthalpy geothermal manifestations in a non‐volcanic setting. This study investigates the geothermal potential of the region through the integration of satellite‐derived gravity data and geological observations.

SWOT Observations Constrain a 4D‐Var State Estimate of the California Current System

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission provides high‐resolution sea surface height (SSH) observations at 2‐km spacing, resolving submesoscale features typical of ageostrophic motions and associated with instabilities. Here, we demonstrate the assimilation of SWOT data into a regional configuration of the MITgcm for the ...

A Transient Coastal Uplift Event Revealed by Pleistocene Marine Terraces Along the 2015 M8.3 Illapel Earthquake Rupture, Chile

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Uplifted Pleistocene marine terraces in the Illapel area along the forearc of central Chile record spatially and temporally variable uplift rates on glacial‐cycle timescales. However, the underlying mechanisms for this uplift variability and its potential relationship with the megathrust‐earthquake cycle remain poorly understood.
