Fluids, 2022 By rotary empirical orthogonal function and coastal-trapped wave mode analyses, we analyzed current velocity data, collected from 2001 to 2016. The data were obtained by an acoustic Doppler current profiler, deployed upward at a location of 41°39.909′ N,

Continuous measurements of discharge from a horizontal acoustic Doppler current profiler in a tidal river [PDF]
, 2009 Acoustic Doppler current profilers (ADCPs) can be mounted horizontally at a river bank, yielding single-depth horizontal array observations of velocity across the river.

Imaging of Artificial Bubble Distribution Using a Multi-Sonar Array System
Journal of Marine Science and Engineering, 2022 Bubble clusters present in seawater can cause acoustic interference and acoustic signal distortion during marine exploration. However, this interference can also be used as an acoustic masking technique, which has significant implications for military ...

Subtidal water level variation controlled by river flow and tides [PDF]
, 2009 Subtidal water level dynamics in the Berau river, East Kalimantan, Indonesia, feature a pronounced fortnightly variation. The daily mean water levels at a station about 60 km from the sea are 0.2–0.6 m higher during spring tide than during neap tide.

Submerged dunes and breakwater embayments mapped using wave inversions of shore-mounted marine X-Band radar data [PDF]
, 2010 Surveying very shallow coastal areas, particularly around coastal defences, can be a logistically difficult and time consuming process. A marine-radar based bathymetry mapping technique has been used to remotely map the embayments around a series of ...

Measurements of the Outflow Along the Eastern Border of Planinsko Polje, Slovenia
Acta Carsologica, 2017 Planinsko Polje is the westernmost active polje of Dinaric karst. It is a typical overflow-structural polje, with springs on the southern side feeding the superficial flow of Unica River.

3D reconstruction of ocean velocity from high-frequency radar and acoustic Doppler current profiler: a model-based assessment study [PDF]
Ocean Science, 2020 The effective monitoring and understanding of the dynamics of coastal currents is crucial for the development of environmentally sustainable coastal activities in order to preserve marine ecosystems as well as to support marine and navigation safety ...

Measuring a Lagrangian drifter’s slip with an onboard ADCP
MethodsX, 2019 A perfect Lagrangian drifter should move with the same velocity as the water volume that it is following. Deviations from this ideal will result in a relative velocity between the drifter’s drogue and its surrounding water, commonly named “slip ...
