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,

Hydraulic Effects of Channel Realignment and Floodplain Reconnection in a Headwater Stream

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Channel realignment and floodplain reconnection are increasingly used as nature‐based solutions for flood management, yet their hydraulic effects remain poorly quantified in field settings of moderate‐gradient, small order channels. This study examines the impact of such interventions on hydraulic response in a headwater catchment, Goldrill ...

A Numerical Study of the Effects of Density Contrast on Flow, Turbulence, and Mixing at the Negro/Solimoes Confluence, Brazil

Water Resources Research, Volume 62, Issue 5, May 2026.
Abstract Eddy‐resolving numerical simulations are conducted to investigate the effects of density contrast between the confluent flows on hydrodynamics, coherent structures and mixing downstream of the confluence between the Negro and Solimões Rivers, Brazil, which is characterized by both a large discharge (>100,000 m3/s) and a large aspect‐ratio (W/D

Impact of wave–current coupling on the bottom boundary layer in Bohai Bay

Frontiers in Marine Science
Sediment resuspension primarily occurs within the bottom boundary layer (BBL) of water bodies, particularly in silty coastal environments, and helps form the fluid mud layer (FML).

Estimating Zooplankton Biomass Distribution in the Water Column Near the Endeavour Segment of Juan de Fuca Ridge Using Acoustic Backscatter and Concurrently Towed Nets [PDF]

Oceanography, 2012
Logistical challenges, time, and the cost of towed net surveys make it difficult to obtain estimates of secondary biomass and production in the open ocean outside the summer sampling season. Alternate approaches are sometimes needed.

Prognostication of Liver Disease Patients via the WFUMB ‘Rule‐of‐4’ Algorithm Using SSI‐2D‐SWE‐Based Liver Stiffness Measurement

Liver International, Volume 46, Issue 5, May 2026.
ABSTRACT Background The World Federation for Ultrasound in Medicine and Biology (WFUMB) guidance update 2024 proposed a ‘rule‐of‐4’ using ARFI liver stiffness measurement (LSM) to stratify the risk of decompensation events. This rule identifies advanced chronic liver disease (ACLD) at a threshold of ≥ 13 kPa and indicates a high probability of ...

Evolution of secondary cellular circulation flow above submarine bedforms imaged by remote sensing techniques [PDF]

, 2013
Normalized radar cross section (NRCS) modulation and acoustic Doppler current profiler (ADCP) measurements above submarine sand ribbons and sand waves are presented. The two study areas are located in the Southern Bight of the North Sea at the Birkenfels

Influx of Bay of Bengal Waters and Stirring Trends in the Arabian Sea Based on Satellite Altimetry

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Freshwater transport and stirring affect air–sea interactions in the Arabian Sea (AS). Using three decades of satellite‐based surface currents, this study examines (a) the volume influx of water masses into southeastern AS from the Bay of Bengal (BoB), and (b) horizontal stirring over seasonal to interannual timescales in the AS.

Bacteria as Passive Passengers in the Equatorial Pacific Biological Carbon Pump

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bacteria are important agents modulating the efficiency of the ocean's biological carbon pump (BCP). The long‐standing view considers bacteria as degraders of sinking particulate organic carbon (POC), yet underappreciates their contribution to carbon export.
