Direct Measurements of the Malvinas Current Velocity Structure
Journal of Geophysical Research: Oceans, 2021 AbstractDirect velocity measurements of the Malvinas Current (MC) were carried out on multiple occupations of five transects across the flow using a Shipborne Acoustic Current Profiler (SADCP) on the R/V Akademik Sergey Vavilov and Akademik Mstislav Keldysh.

In‐situ measurements of velocity structure within turbidity currents [PDF]
Geophysical Research Letters, 2004 Turbidity currents are thought to be the main mechanism to move ∼500,000 m3 of sediments annually from the head of the Monterey Submarine Canyon to the deep‐sea fan. Indirect evidence has shown frequent occurrences of such turbidity currents in the canyon, but the dynamic properties of the turbidity currents such as maximum speed, duration, and ...

Traveling-Wave Electrokinetic Micropumps: Velocity, Electrical Current, and Impedance Measurements [PDF]
Langmuir, 2008 An array of microelectrodes covered in an electrolyte and energized by a traveling-wave potential produces net movement of the fluid. Arrays of platinum microelectrodes of two different characteristic sizes have been studied. For both sizes of arrays, at low voltages (

Velocity Calibration of Doppler Current Profiler Transducers
Journal of Marine Science and Engineering, 2020 Doppler current profilers are used in oceanography to measure oceanic circulation but also in hydrology to calculate the flow of rivers. They allow the retrieval of water mass profiles in terms of velocity and direction.

Japan Tsunami Current Flows Observed by HF Radars on Two Continents
Remote Sensing, 2011 Quantitative real-time observations of a tsunami have been limited to deep-water, pressure-sensor observations of changes in the sea surface elevation and observations of sea level fluctuations at the coast, which are essentially point measurements ...

Free-Surface Velocity Measurement Using Direct Sensor Orientation-Based STIV
Micromachines, 2022 Particle image velocimetry (PIV) is a quantitative flow visualization technique, which greatly improves the ability to characterize various complex flows in laboratory and field environments. However, the deployment of reference objects or ground control
