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 ...

Some key facts for the realization of a modern National Geodetic Reference System/Frame: The Hellenic case [PDF]

Micro, Macro & Mezzo Geoinformation
The realization of a modern National Geodetic Reference System/Frame (NGRSF) for each country plays a crucial role in many applications, such as cadastre, public works, and, lately, the monitoring of climate change (at least at the local scale).

The Importance of the Coordinate Transformation Process in Using Heterogeneous Data in Coastal and Marine Geographic Information System

Journal of Marine Science and Engineering, 2020
Coastal and Marine Geographic Information Systems (CMGISs) permit to collect, manage, and analyze a great amount of heterogeneous data concerning coastal, sea, and ocean environments, e.g., nautical charts, topographic maps, remotely sensed images.

The Magmatic‐Hydrothermal System of the Three Sisters Volcanic Cluster, Oregon, Imaged From Field Gravity Measurements

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract From 2019 to 2024, gravity surveys were conducted at the Three Sisters volcanic cluster (TSVC), measuring 246 gravity sites using a spring relative gravimeter. We calculated the residual Bouguer anomaly and identified three main zones with negative anomalies, ranging from −4 to −8 mGal, located southwest and west of South Sister, within an ...

Three Drivers of 21st‐Century Changes in Ocean Tides

Journal of Geophysical Research: Oceans, Volume 131, Issue 1, January 2026.
Abstract Numerical model simulations are conducted to study the response of barotropic ocean tides to 21st‐century climate change, as manifested by sea level rise, increasing ocean stratification, and expanding Antarctic ice shelf cavities. Emphasis is placed on surface elevations, with projections of M2 ${\mathrm{M}}_{2}$, S2 ${\mathrm{S}}_{2}$, K1 ${\

Sea Lavender Reimagined: Keystone Halophytes in Salt Marsh Blue Carbon Dynamics

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 1, January 2026.
Abstract Salt marshes are ecologically and socio‐economically valuable intertidal ecosystems that have suffered rapid losses worldwide. As a blue carbon ecosystem (BCE), they are efficient sinks and long‐term reservoirs of organic carbon (OC), with vital roles in the global carbon cycle.
