Bubble Clouds in Coastal Waters and Their Role in Air-Water Gas Exchange of CO2

Journal of Marine Science and Engineering, 2015
Bubbles generated by breaking waves can drive significant gas exchange between the ocean and atmosphere, but the role of bubble-mediated gas transfer in estuaries is unknown.

Glacier Retreat Amplifies Interannual Variability in Watershed Runoff, Organic Carbon and Nutrient Yields

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Glacier retreat is projected to drive major shifts in the hydrology of many high‐elevation and high‐latitude watersheds. In particular, future decreases in glacier runoff are hypothesized to reduce the stability of hydro‐biogeochemical export.

Ocean Bottom Seismometers Provide Direct Measurements of Pulsed‐Structure and Turbulence of Turbidity Currents Overspilling From a Submarine Channel

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Turbidity currents transport vast amounts of sediment, carbon, and heat along submarine channels, yet their overspill onto channel‐levees and abyssal mixing remain poorly constrained due to lack of direct observations. Ocean‐bottom seismometers (OBS) deployed on the Congo Canyon–Channel levees captured the structure and turbulence of overspill

Listening to the Atmosphere: Using Infrasound Observations to Infer Atmospheric Conditions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The stratosphere and mesosphere are important regions for the prediction of weather at the Earth's surface for medium‐ and long‐range forecasts. The availability of observations in these layers is lower than that of the troposphere, especially for the dynamics. While seeking new observational sources is important, there are existing infrasound

Ultrasound in Women's Health: Mechanisms, Applications, and Emerging Opportunities

Advanced Materials, Volume 38, Issue 14, 6 March 2026.
As healthcare moves toward decentralization, ultrasound technologies are evolving from strictly imaging tools in clinical settings into versatile diagnostic and therapeutic platforms, with growing roles addressing women's health needs. This review highlights how ultrasound's underlying physical mechanisms can be harnessed to reduce disparities in women'

Data‐Driven Feedback Identifies Focused Ultrasound Exposure Regimens for Improved Nanotheranostic Targeting of the Brain

Advanced Science, Volume 13, Issue 13, 3 March 2026.
Machine learning models predict in real time the onset of harmful microbubble collapse during microbubble‐enhanced focused ultrasound (MB‐FUS) and enable dynamic adjustment of sonication to prevent cavitation‐induced damage. This predictive control expands the safe operating window for bloodbrain barrier opening, enhancing nanoparticle delivery and ...

Morphological instability in restored intertidal flats: How anthropogenic structures drive early‐stage evolution

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
The study focusses on the morphological evolution of worldwide restored intertidal flats. These intertidal flats initially experience high sedimentation rates after the opening of the connection with open waters. The anthropogenic structures cause high morphological instability and are eroded, leading to a self‐cannibalisation of the system.

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.
