Modelling the Effectiveness of Vegetative Nature‐Based Solutions for Coastal Flood Risk Mitigation

Journal of Flood Risk Management, Volume 18, Issue 2, June 2025.
ABSTRACT Traditional grey solutions, such as seawalls, are increasingly recognised as being unsustainable for long‐term coastal flood risk management, due to high costs and negative environmental impacts. In response, vegetative nature‐based coastal solutions (NBCS), such as saltmarshes, are being increasingly proposed as a more sustainable alternative

A procedure for developing an acceptance test for airborne bathymetric lidar data application to NOAA charts in shallow waters [PDF]

, 2013
National Oceanic and Atmospheric Administration (NOAA) hydrographic data is typically acquired using sonar systems, with a small percent acquired via airborne lidar bathymetry for near‐shore areas.

Assessment of the spatial distribution of Chondria tumulosa, a nuisance macroalga at Manawai in Papahānaumokuākea Marine National Monument using high‐resolution satellite imagery

Journal of Phycology, Volume 61, Issue 3, Page 722-736, June 2025.
Abstract In 2019, a red macroalgal species, Chondria tumulosa, was discovered overgrowing native coral and algal species and changing the benthic communities of Manawai (Pearl and Hermes Atoll) in Papahānaumokuākea Marine National Monument (PMNM). The main objective of this study was to assess the spatial distribution of C. tumulosa across the forereef

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 ...

Reconstructing Total Water Storage Anomalies Over the Lake Victoria Basin (1971–2022) Using an Enhanced RecNet Model

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Relatively short records of Total Water Storage Anomalies (TWSA) from the Gravity Recovery and Climate Experiment (GRACE) and its Follow‐On (GRACE‐FO) missions have impeded our understanding of their full range and long‐term variability over the Lake Victoria Basin (LVB).

On the isoperimetric Riemannian Penrose inequality

Communications on Pure and Applied Mathematics, Volume 78, Issue 5, Page 1042-1085, May 2025.
Abstract We prove that the Riemannian Penrose inequality holds for asymptotically flat 3‐manifolds with nonnegative scalar curvature and connected horizon boundary, provided the optimal decay assumptions are met, which result in the ADM$\operatorname{ADM}$ mass being a well‐defined geometric invariant.

The Canadian Geodetic Vertical Datum of 2013 (CGVD2013)

Geomatica, 2016
The Canadian Geodetic Vertical Datum of 2013 (CGVD2013) is the first major update to the vertical datum in Canada in almost 100 years. Canada is not only moving to a new vertical datum, but it is also using a modernized approach to realize it. The modernization of the height reference system is necessary to make it compatible with Global Navigation ...

Multi‐annual variability of storm events and morphological response in the SW Iceland: The Valahnúkamöl boulder barrier

Earth Surface Processes and Landforms, Volume 50, Issue 6, May 2025.
Located on the high‐energy coast of SW Iceland, the boulder barrier of Valahnúkamöl experienced important morphological changes associated with the morphogenetic impact of storm events over annual to pluri‐decadal timescales. Abstract While many studies have highlighted the high mobility of gravel/pebble beaches due to storm waves, further research is ...
