A CODAS (Common Ocean Data Access System) database is a way to store and access oceanographic data. It is most commonly used with ADCP (Acoustic Doppler Current Profiler) data. “CODAS processing” refers to the steps used to turn ADCP data into something valuable to science.
“CODAS processing” is like box of tools to manipulate data stored in the CODAS database. Quick_adcp.py is like a “black box” for using these tools in a standard order for a variety of ADCP datasets. This black box has removable side panel to allow the user to configure and run all the underlying processing steps. The programs are Open Source so nothing is hidden.
“UHDAS” is a data acquisition system written at the University of Hawaii that acquires data from RDI ADCPs and ancillary serial feeds (eg. gps, gyro, accurate heading device...) and uses CODAS processing to incrementally build a dataset of averaged, edited ocean velocities for each ADCP and ping type specified.
Documentation has accumulated over the years as acquisition programs, instruments, and processing programs have changed. Some of the old (but highly detailed) documentation contains references that are obsolete, but the old data are still out there, and the same problems keep occurring. Much of it is still used and highly relevant.
UHDAS+CODAS Documentation is under transition, as we gradually include more of it under the unifying framework of Sphinx. The full documentation is available at various entry points:
at sea on vessels with UHDAS acqusition systems, at
on your computer, if you install the CODAS suite of ADCP processing
