Formation process of the gravel‐dominated deposit from the 2011 Tohoku‐oki tsunami in Ofunato, northeastern Japan, inferred by integrating sedimentology and tsunami modelling

Sedimentology, EarlyView.
ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

The united geodetic vertical network of Latvia and Lithuania

Geodesy and Cartography, 2012
A unified and continuous national vertical network is the back-bone for geodesy, cartography, civil engineering and global positioning. International institutions are working to reach homogenous and unified vertical datum all around the globe.

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.

Seamless vertical datum model over Sarawak region using KTH method / Nurfarhah Razali [PDF]

, 2021
Sarawak had known as a rugged topographic area because it had many mountains, dense rainforest and much of it protected parkland in Sarawak area. Because of that, the traditional levelling network in Sarawak was difficult to carry out. When the levelling

Análisis de la evolución temporal del datum vertical brasileño de Imbituba

Revista Cartográfica, 2019
Actualmente, los temas más centrales de Geodesia se vinculan a la provisión de un Sistema de Referencia Global único, al que puedan vincularse de forma unívoca y con exactitud los cambios globales de carácter geométrico y físico.

Inundation and Sediment Supply Predict Annual but Not Centennial Carbon Accumulation in Tidal Wetlands Across Land‐Use Types

Global Biogeochemical Cycles, Volume 40, Issue 7, July 2026.
Abstract Despite growing interest in the contributions of tidal wetlands to natural climate solutions, data remain scarce on how land use affects their carbon accumulation rates (CAR). Additionally, environmental factors driving the large observed variability in CAR among sites are poorly understood.

Intercontinental height datum connection with GOCE and GPS-levelling data

Journal of Geodetic Science, 2012
In this study an attempt is made to establish height system datum connections based upon a gravity field and steady-state ocean circulation explorer (GOCE) gravity field model and a set of global positioning system (GPS) and levelling data. The procedure

Evaluation of grace-based combined geopotential model over the Baltic countries

Geodesy and Cartography, 2012
Nowadays, many geodetic and engineering applications require that the two essential components of the vertical positioning – the height and the corresponding reference surface (geoid), are determined precisely.

Role of Volcano‐Tectonic Interactions During Early‐Phase Magma‐Assisted Continental Rifting

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We study volcanic‐tectonic interactions during the early phase of rifting in the Natron Rift, a magmatic segment of the East African Rift System. We use the open‐source crustal deformation modeling code, PyLith, to model deflation during the 2007–2008 explosive eruptions and inflation during 2016–2023.

Advancing High‐Resolution Lake Bathymetry Reconstruction Through Geomorphologically Informed Deep Learning in High Mountain Asia

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Accurate three‐dimensional (3D) lake bathymetry reconstruction is critical for water resources assessment and hydrological modeling yet remains constrained by data scarcity and oversimplified geometric assumptions. To address these challenges, we propose the Geomorphologically informed deep learning (GIDL) framework for high‐resolution 3D lake
