Lowered Acoustic Doppler Current Profiler (LADCP)

Lowered Acoustic Doppler Current Profiler (LADCP)

As part of the US component of the CLIVAR/CO2 repeat hydrography program measurements of quasi-instantaneous vertical profiles of horizontal ocean velocities using a Lowered Acoustic Doppler Current Profiler (LADCP) were taken. Final LADCP processing was performed using the LDEO processing software by Andreas Thurnherr (Lamont-Doherty Earth Observatory of Columbia University) through 2008 and by University of Hawaii ""currents"" group (Firing/Hummon/Ascani) since 2009. This project is supported by NSF grants OCE-0223869 and OCE-0752970. The continous-in-time upper-ocean velocities from Shipboard Acoustic Doppler Current Profiler (SADCP) are available on the University of Hawaii "currents" group's website.

Profile data are also available via a Google Map API on the LADCP projects page.
