Journal of Hydroinformatics, 2022 The ‘Bajo Grande’ Wastewater Treatment Plant has a design capacity of 2.78 m3/s, and discharges into the Suquia River (Córdoba, Argentina). The river has an average flow rate of 10 m3/s, with lower values during the summer. Currently, the treatment plant

Ocean Science (OS), 2019 . Diel vertical migration (DVM) is a survival strategy adopted by zooplankton that we investigated in the Corsica Channel using acoustic Doppler current profiler (ADCP) data from April 2014 to November 2016.

Surveying the upper Ocean with the Ocean Surveyor - a new Phased Array Doppler Current Profiler [PDF]
, 2003 A new shipboard current profiler, a 75-kHz ocean surveyor, was operationally used during two research cruises in the tropical Atlantic and the subpolar North Atlantic, respectively. Here, a report is presented on the first experience with this instrument

Nature Communications, 2017 Satellite altimeters resolution poorly capture mesoscale signals in the upper ocean. Here, the authors analyse shipboard Acoustic Doppler Current Profiler measurements from the northwest Pacific, and show that balanced geostrophic flows and unbalanced ...

Analysis of tidal currents in the North Sea from shipboard acoustic Doppler current profiler data
Continental Shelf Research, 2018 North Sea tidal currents are determined by applying harmonic analysis to ship-borne acoustic Doppler current profiler data recorded from 1999 to 2016, covering large areas of the northern North Sea.

Lagrangian measurements of turbulent dissipation over a shallow tidal flat from pulse coherent Acoustic Doppler Profilers [PDF]
, 2012 We present high resolution (25 mm spatial, 8 Hz temporal) profiles of velocity measured over a shallow tidal flat using pulse-coherent Acoustic Doppler Profilers mounted on surface drifters.

Acoustic Doppler current profiler observations of herring movement [PDF]
ICES Journal of Marine Science, 2003 Abstract Observations were made of over-wintering (December 1997) and migrating (January 1998) Norwegian, spring-spawning herring (Clupea harengus) using a moored 307 kHz acoustic Doppler current profiler (ADCP). The location of herring in ADCP data is identified by regions of volume-backscatter strength greater than −60 dB re 1 m−1. The

Impact of acoustic Doppler current profiler (ADCP) motion on structure function estimates of turbulent kinetic energy dissipation rate [PDF]
Ocean Science, 2022 Turbulent mixing is a key process in the transport of heat, salt, and nutrients in the marine environment, with fluxes commonly derived directly from estimates of the turbulent kinetic energy dissipation rate, ε. Time series of ε estimates are therefore

Water Resources Research, 2019 Repeated measures experiments can be conducted to empirically estimate the uncertainty of a stream gauging method, such as the widespread moving‐boat acoustic Doppler current profilers (ADCPs) approach.

The parameterisation of turbulence in the marine environment [PDF]
, 2016 There are many problems in the fields of flow modelling around structures and tidal stream energy yield analysis which require a thorough understanding of the turbulent and time-averaged flow speeds in marine environments.
