Combining T/P altimetric data with hydrographic data to estimate the mean dynamic topography of the North Atlantic and improve the geoid [PDF]

Annales Geophysicae, 1998
The mean dynamic topography of the surface of the North Atlantic is estimated using an inverse model of the ocean circulation constrained by hydrographic and altimetric observations.

Determination of deflection of the vertical from geoid heights

Geodetski vestnik, 2010
The geoid model represents part of the national coordinate system. It can be used for the purpose of GNSS-levelling, but the use of geoid heights also improves incorporation of terrestrial observations into the state coordinate system. In GNSS levelling tasks, geoid heights are obtained from the geoid model, but with terrestrial observations the ...

Elevated Asthenospheric Temperature Driving the Partial Melting of Enriched Lithospheric Mantle Feeding the DM‐EM1 Mixing‐Type Magmatism of the Jingpohu Volcano in Eastern NE China: Evidence From Teleseismic P‐Wave Attenuation

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract The origin of a binary‐mixing of DM and EM1 sources for the Cenozoic intraplate volcanism in eastern Northeast China is yet unclear. Seismic attenuation imaging is a tool that can shed light on this question. Here we present the first map of teleseismic P‐wave attenuation across Northeast China.

Referencing regional geoid-based vertical datums to national tide gauge networks

Journal of Geodetic Science, 2012
The objective of this study is to investigate the best means for referencing a regional geoid-based vertical datum to a network of tide gauges. In this study, a network of 27 tide gauge stations scattered along the coasts of Canada are used in order to ...

Describing the Global Gravity Field of Mars With Lithospheric Flexure and Deep Mantle Flow

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract The volcanic complex Tharsis Region on Mars is known for its numerous volcanoes on top of the crust, elevated topography (doming), and a long‐wavelength gravity anomaly correlated with the region. Flexural modeling of the lithosphere has commonly been used to understand the relationship between observed topography, crustal structure, and ...

Evaluating SWOT in the Coastal Zone: Comparisons With Tide Gauge and Airborne LiDAR in the Bristol Channel and Severn Estuary, UK

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Traditional nadir altimeters struggle with coastal water surface elevation (WSE) measurement and fine‐scale river‐estuary interactions, due to land‐water signal interference and their wide inter‐track spacing. The wide‐swath Surface Water and Ocean Topography (SWOT) mission, using a new Ka‐band radar interferometer, aims to address these ...

Progress in satellite gravity recovery from implemented CHAMP, GRACE and GOCE and future GRACE Follow-On missions

Geodesy and Geodynamics, 2015
Firstly, the Earth's gravitational field from the past Challenging Minisatellite Payload (CHAMP) mission is determined using the energy conservation principle, the combined error model of the cumulative geoid height influenced by three instrument errors ...

Spaceborne Canopy Height Products Should Be Complemented With Airborne Laser Scanning Data: Toward a European Canopy Height Model

Earth and Space Science, Volume 13, Issue 1, January 2026.
Abstract Measuring and mapping vegetation structure is essential for understanding the functioning of terrestrial ecosystems and for informing environmental policies. Recent years have seen a growing demand for high‐resolution data on vegetation structure, driving their prediction at fine resolutions (1–30 m) at state, continental, and global spatial ...

Airborne geoid mapping of land and sea areas of East Malaysia

Journal of Geodetic Science, 2017
This paper describes the development of a new geoid-based vertical datum from airborne gravity data, by the Department of Survey and Mapping Malaysia, on land and in the South China Sea out of the coast of East Malaysia region, covering an area of about ...

Distribution Models Reveal Important Coastal Habitats for Endangered Leatherback Sea Turtles

Diversity and Distributions, Volume 32, Issue 1, January 2026.
ABSTRACT Aim With the development and operation of offshore wind farms along the United States East Coast, it is imperative that we understand the distributions of vulnerable species so we can track and predict potential interactions. We focused on leatherback sea turtles (Dermochelys coriacea) as they depend on this region for important stages of ...
