Laser bathymetry on rough riverbed channels: State‐of‐the‐art and future prospects
Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.This literature review found that topo‐bathymetric LiDAR has been successfully used to capture the structures of rough riverbeds and detect large boulders. While all of the studies that were reviewed used sensors that were operated from fixed‐wing aircraft, few studies have yet tested UAV‐borne sensors on rough riverbeds, despite the potential offered ...

An Overview of Tsunami Hazards in the Southwest Pacific Ocean
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 2, June 2026.The southwest Pacific region is geologically complex and exhibits all the principal causes of tsunami generation. While contemporary events and historical catalogs indicate that trans‐Pacific tsunamis have affected this area (∼18% of tsunamis reported globally), it is unique in that a large part of the tsunami effects over the ∼200‐year historical ...

Geosciences, 2020 Backscatter data from multibeam echosounders are commonly used to classify seafloor sediment composition. Previously, it was found that the survey azimuth affects backscatter when small organized seafloor structures, such as sand ripples, are present ...

Incorporating environmental DNA metabarcoding for improved benthic biodiversity and habitat mapping
Remote Sensing in Ecology and Conservation, Volume 12, Issue 3, Page 444-461, June 2026.Seafloor imagery is commonly used to collect information about the distribution of benthic organisms in order to generate habitat and biodiversity maps. Recent advances in genomics (e.g., environmental DNA; eDNA) show potential to complement video surveys for habitat mapping, but there have been few examples testing this.

Geomorphology and substrate of Galway Bay, Western Ireland
Journal of Maps, 2020 A combination of multibeam bathymetry and backscatter, LiDAR altimetry and bathymetry, satellite images, and hydrodynamic model outputs were used to map the seafloor and coastline of Galway Bay (western Ireland).

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.Abstract We present a comprehensive multidisciplinary investigation of the Healy submarine volcano in the southern Kermadec arc, northeast of New Zealand. We show the first results of sidescan‐sonar data collected at a submarine arc volcano by an Autonomous Underwater Vehicle (AUV).
