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,

Assessing the Spatiotemporal Variability in Geotechnical Sediment Properties of Beach Cusps on a Sandy Beach

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract This study examined the spatiotemporal variability in geotechnical properties of beach cusp sediments on a sandy beach and tested if such variability can be used for cusp monitoring from satellite imagery. Specifically, sediment properties (including moisture content (w), relative density (Dr), sediment strength (QSBC) and friction angle (ϕ ...

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 ...

Global Analysis of Shallow Underwater Fish Observation Research: 70 Years of Progress, Persistent Geographic Biases and a Path Forward

Fish and Fisheries, Volume 27, Issue 3, Page 607-626, May 2026.
ABSTRACT Marine ecosystems are increasingly threatened by overfishing, pollution, coastal development and climate change, underscoring the need for long‐term, representative information on key fish populations and habitats to inform management and policy.

Magnitude and variability of blood pressure and renal vascular conductance responses to postural changes, exercise, and cold in black adults: A pilot study

Physiological Reports, Volume 14, Issue 9, May 2026.
Abstract We developed a noninvasive approach to measure vascular responses to sympathetic stimuli. We hypothesized that standing, handgrip exercise, or cold exposure would raise blood pressure (BP) and lower renal vascular conductance (RVC). BP was recorded continuously and renal arterial velocity was measured using renal Doppler ultrasound.
