Observing and Predicting Coastal Erosion at the Langue de Barbarie Sand Spit around Saint Louis (Senegal, West Africa) through Satellite-Derived Digital Elevation Model and Shoreline

open access: yesRemote Sensing, 2021
Coastal erosion at Saint Louis in Senegal is affecting the local population that consists of primarily fishermen communities in their housing and their access to the sea.

Rethinking microtidal systems: Tidal signatures in the fluvial deposits of the Po River, Italy

open access: yesSedimentology, EarlyView.
ABSTRACT In microtidally influenced rivers, tides are generally assumed to leave virtually no signatures in the sedimentary record. However, this hypothesis has been surprisingly poorly tested using modern river analogues, which provide an opportunity to assess whether sedimentary signatures of microtidal regimes can develop in rivers that lack ...

80 Years of Coastal Erosion and Accretion in Aotearoa New Zealand

open access: yesNew Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 4, December 2026.
Understanding historical coastal change over multi‐decadal timescales is fundamental for coastal hazard assessment and adaptation planning. In Aotearoa New Zealand (NZ), national‐scale coastal change information has historically been fragmented, limited in spatial resolution or constrained to relatively short timeframes.

From the Gulf of Guinea to the Global Stage: Africa’s Voice in the Age of Climate Intervention

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Climate intervention technologies, Solar Radiation Management (SRM) and marine Carbon Dioxide Removal (mCDR), are moving from theoretical proposal to serious policy consideration, yet the scientific communities and governance frameworks shaping these decisions remain concentrated in the Global North, while the populations most exposed to ...

Autocyclic Secondary Channels Stabilize Deltaic Islands Undergoing Relative Sea Level Rise

open access: yesGeophysical Research Letters, 2022
Understanding what sets the size and stability of deltaic islands is critical for predicting how deltas will respond to sea level rise. Models of overbank sedimentation produce an exponentially decaying sedimentation profile, seemingly incompatible with ...

The Overlooked Role of Alongshore Beach Non‐Uniformity in Short‐Term Shoreline Variability

open access: yesGeophysical Research Letters, Volume 53, Issue 21, 16 November 2026.
Abstract Long‐term beach monitoring and satellite‐derived shoreline products are typically validated, and shoreline models calibrated, along cross‐shore transects. Open sandy beaches, however, are rarely uniform alongshore, because crescentic megacusps migrate past fixed transects, and their effect on single‐transect records remains unquantified.
