Measurement of backscattering strength of artificial bubbles in the Southern Sea of the Korean Peninsula

open access: yesFrontiers in Marine Science
Bubbles greatly affect the propagation of sound waves as the acoustic characteristics of a bubble cluster in water are distinct from those of undisturbed water.

Nitrate Distribution in Pacific Winter Water Along the Northern Edge of the Chukchi Sea

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Nutrient‐rich, Pacific‐origin winter water (PWW) is a primary source of nitrate for the western Arctic Ocean, spurring primary production at the base of the food web. This cold water exits the Chukchi Sea shelf via Herald Canyon and Barrow Canyon, which feed the eastward‐flowing Chukchi Shelfbreak Jet (CSJ) and the westward‐flowing Chukchi ...

Preliminary Performance Assessment of the Wave Parameter Retrieval Algorithm from the Average Reflected Pulse

open access: yesRemote Sensing
To obtain new information about surface waves, it is proposed to use an underwater acoustic wave gauge, and an assessment of its effectiveness can be performed using a numerical simulation and field experiment.

The Frequency Response of Acoustic Doppler Current Profilers

open access: yes, 2014
The lifespan of a tidal turbine is strongly affected by the unsteady loading it experiences, so knowledge of the mean flow speed is not sufficient: unsteadiness must also be quantified. One of the most common turbulence measurement devices in the marine environment is the Acoustic Doppler Current Profiler (ADCP).

Suspended sediment dynamics above submerged compound sand waves observed during a tidal cycle [PDF]

open access: yes, 2016
Detailed Acoustic Doppler Current Profiler (ADCP) data of the three-dimensional current-field, echo intensity, modulation of suspended sediment concentration (SSC), and related water level and wind velocity have been analyzed as a function of water depth

Variability of currents and mixing processes during the onset of the equatorial cold tongue in the Atlantic [PDF]

open access: yes, 2012
The heat content of the surface water masses is important for the circulation of the oceans and the atmosphere. The surface layer serves as a medium for the ocean-atmosphere exchange and thereby significantly affects the dynamics of our climate.
