Seabed classification in the Gulf of Alaska from acoustic surveys using deep learning

Limnology and Oceanography: Methods, Volume 24, Issue 5, May 2026.
Abstract High‐resolution mapping of seafloor habitats has wide applications for fisheries, conservation efforts, offshore infrastructure planning, mineral extraction, and scientific modeling. This study leverages existing widespread single‐beam acoustic data and machine learning to create habitat maps for the Gulf of Alaska at a spatial resolution of ...

Reshaping of San Jose Island, TX, USA, by Unconfined Washover and Channelized Washout During Hurricane Harvey

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract Hurricane Harvey (2017) produced 31 net‐erosional washout channels on San Jose Island, Texas, USA, where offshore‐directed flows cut through two dune ridges and the beach. Channel growth was affected by natural, pre‐existing aeolian topography, rather than prior washover channels or infrastructure. We investigate how offshore directed outwash,

CheckEM: An open‐source toolkit for standardising, cleaning and visualising stereo‐video fish survey data

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1606-1616, May 2026.
Abstract Effective research and monitoring requires accurate, interoperable and representative data. Stereo‐video based methods are commonly used to survey fish and are rapidly expanding globally due to their cost‐effectiveness, ability to provide accurate body size measurements, non‐destructive approach and capacity to create permanent data records ...
