Acoustic Doppler Current Profiling

Specializing in environmental research, mapping, and reporting, AFFILIATED RESEARCHERS utilizes its industry proven equipment, and trained personnel to provide acoustic Doppler current profiling (ADCP) in lakes, harbors, rivers, canals, estuaries, and marine environments.

Thousands of water velocity and direction measurements are collected using an ADCP, to develop a database of the hydrologic conditions and better understand the effect of currents on habitat or the movement of sediments.

While navigating its survey vessel along selected transects, thousands of water velocity measurements are collected using the ADCP, to develop a database of the hydrologic conditions and to better understand the effect of currents on habitat or the movement of sediments.

The ADCP develops water velocity-direction-position data into discrete, data “cells” arranged within each respective survey transect.  The geo-spatial position of each of the discrete cells is accurately located to centimeter accuracy using a real time kinematic (RTK) GPS. The vertical positions of each of the discrete cells are accurately located by the ADCP.

Hydrographic software is used to accurately locate and delineate the numerous discrete water velocity-direction cells within the surveyed transect.  The ADCP data within each survey transect, or each data cell can be compiled and analyzed to establish maximums, minimums, variation, and correlation.

Analysis of the spatial distribution of the ADCP data can be accurately compiled and analyzed throughout an environment.  The analysis of ADCP data can be compiled into water velocity histograms, or to provide color mosaic depictions of water velocity “contours”.

The data can be compiled and analyzed for correlations relating to weather events, seasons, locations, biological productivity, water quality plumes, as well as other environmental and/or anthropomorphic factors.

AFFILIATED RESEARCHERS experienced technicians are able to provide these services nationwide.
