High Resolution Measurements of the Mean Three-dimensional Flow Field in a Natural River
… developed to measure discharge, boat-mounted acoustic Doppler current profilers (ADCP) are increasingly used in field studies to quantify flow features including mean velocity, boundary shear stress, and sediment motion. Two survey procedures are typically employed with an ADCP. Moving-vessel …

Evaluation of the operational Mercator Global Ocean analysis and forecast system modelled current vector product with in-situ ADCP data in the Southern Benguela upwelling system
Global ocean current vector datasets are frequently used to force, or are assimilated into, local and regional particle tracking and pollutant dispersal models, metocean forecasting platforms, climate analyses, and natural resource management applications. The Operational Mercator global ocean …

Physical constraints on phytoplankton in estuaries and shallow coastal waters
… Using high frequency data, collected from acoustic Doppler current profilers (ADCP) and CTDs, the physical mixing processes within the estuary were determined and combined with high resolution phytoplankton species data to assess the physical pressures on the microalgal community. Initial …

Coastal surface circulation of the Gulf of Cadiz from satellite altimetry measurements
… high-resolution satellite altimetry estimates of current velocities, along with high-resolution wind data from the WRF model, the research provides a comprehensive characterization of surface circulation over the northern shelf of the Gulf of Cadiz. The study compares high-resolution satellite …

From meander bend to oxbow lake: morphodynamics and sedimentology of chute cutoffs
Chute cutoffs are common features of meandering channels. The development of a chute cutoff locally shortens and straightens a meandering river channel, excavating a large volume of floodplain sediment as the chute channel deepens and widens. Bar development at the upstream and downstream ends of …
