CLIVAR/CO2 Repeat Hydrography
Shipboard and lowered ADCP data

This page provides links to vessel-mounted and lowered Acoustic Doppler Current Profiler data collected by the University of Hawaii in support of the CLIVAR/CO2 Repeat Hydrography Program.

Links to vector and contour plots of the velocity data in [gif, jpg, or png] and/or postscript format are provided below.

Selecting "examine data" will access an image map of the cruise track. Selection of any of the labeled sections, by clicking on the letter, will show a vector plot of upper ocean velocities over topography, with temperatures color-coded on the vectors. Contour plots of both zonal and meridional velocity versus depth and the appropriate horizontal dimension are accessible from the vector plots. These plots display shaded velocity values between +/- 100 cm s^-1 typically, with divisions at +/- 10 cm s^-1.

These data were processed at the University of Hawaii. All processing was done on Linux machines. Plots were made in matlab; maps used projections from the m_map package.

Shipboard data are in final form and have been released to the JASADCP archive. Final LADCP processing through 2007 was done by Andreas Thurnherr.
