Tidal Attenuation and Poor Drainage Make Interior Microtidal Marshes Vulnerable to Sea Level Rise

Geophysical Research Letters, Volume 52, Issue 19, 16 October 2025.
Abstract Empirical and simulation models often assume a uniform tidal range across marsh platforms to predict marsh vulnerability to sea level rise (SLR), overlooking the hydrological heterogeneity caused by tidal attenuation and drainage conditions. We measured water level fluctuations at two microtidal marshes in Chesapeake Bay to evaluate how this ...

Recovery of Daily Water Levels in the Sacramento‐San Joaquin Delta, 1915–2023

Geoscience Data Journal, Volume 12, Issue 4, October 2025.
Newly digitized records of daily maximum and minimum water levels have been recovered from 25 distinct locations across the Sacramento/San Joaquin Delta region, extending the period of record by several decades. Analysing longer records will improve understanding of the processes influencing water levels in this dynamic region. ABSTRACT This manuscript

Impact of SRTM and ASTER Terrain Models on Geoid Determination: A Case Study in the High‐Mountainous Region

Earth and Space Science, Volume 12, Issue 10, October 2025.
Abstract An accurate geoid has important consequences for many fields such as engineering applications, underground resource exploration, geophysical surveys, etc. Its precise determination relies on two key data sets: gravity measurements and high‐resolution elevation data, both of which are critical for achieving reliable results.

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 ...
