Within-Event Spatially Distributed Bedload: Linking Fluvial Sediment Transport to Morphological Change [PDF]

, 2012
Maps of apparent bedload velocity are presented along with maps of associated channel change. Apparent bedload velocity is the bias in acoustic Doppler current profiler (aDcp) bottom track (Doppler sonar) due to near-bed particle motion (Rennie et al ...

Activatable smart contrast agents for photoacoustic imaging

Smart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Analysis of in situ water velocity distributions in the lowland river floodplain covered by grassland and reed marsh habitats - a case study of the bypass channel of Warta River (Western Poland)

Journal of Hydrology and Hydromechanics, 2017
The analysis of in situ measurements of velocity distribution in the floodplain of the lowland river has been carried out. The survey area was located on a bypass channel of the Warta River (West of Poland) which is filled with water only in case of ...

Ocean currents and acoustic backscatter data from shipboard ADCP measurements at three North Atlantic seamounts between 2004 and 2015

Data in Brief, 2018
Seamounts are amongst the most common physiographic structures of the deep-ocean landscape, but remoteness and geographic complexity have limited the systematic collection of integrated and multidisciplinary data in the past.

Atlantic salmon (Salmo salar L.) kelt rheotaxis and position choice are influenced by flow velocity and turbulence in a regulated river

Journal of Fish Biology, EarlyView.
Abstract The migratory behaviour of Atlantic salmon kelts is poorly understood. Due to the Atlantic salmon's considerable socio‐economic and ecological importance, their precipitous population abundance declines, and the population resilience potential of salmon kelts, addressing these knowledge gaps is important.

Current monitoring for environmental pollution studies by acoustic Doppler current profiling [PDF]

The Journal of the Acoustical Society of America, 1994
NOAA’s National Ocean Service (NOS) has been measuring and predicting coastal currents for over 100 years. In earlier times, measurements were made with current poles, or propeller-type current meters. In the late 1980’s, acoustic Doppler current profilers (ADCPs) were widely adopted.

First Strike: Description of the Events at the First Salmon Farm Affected by the 2025 Algal Bloom in Northern Norway

Journal of Fish Diseases, EarlyView.
ABSTRACT Harmful algal blooms (HABs) are a threat to fish welfare, occurring suddenly and unexpectedly causing significant consequences for fish and salmon farmers worldwide. Norwegian farmers have been facing this challenge at irregular intervals since the very beginning of the industry. This report describes the events on the first fish farm affected

Variations in downslope activity and bottom current dynamics in a land‐detached submarine channel system since the Last Glacial Maximum

Sedimentology, EarlyView.
ABSTRACT The Gollum Channel System is a land‐detached large‐scale canyon‐channel system situated offshore southwest Ireland on the Northeast Atlantic margin. The system has been considered inactive with downslope gravity flows since the last glacial period, but geophysical data in some of its branches do suggest Holocene activity.
