About
DOLfYN is a library of tools for reading, processing, and analyzing data from oceanographic velocity measurement instruments such as acoustic Doppler velocimeters (ADVs) and acoustic Doppler current profilers (ADCPs). It includes tools to
Read in raw ADCP/ADV datafiles
QC velocity data
Rotate vector data through coordinate systems (i.e. beam to instrument to Earth to principal frames of reference)
Motion correction for ADV velocity measurements (via onboard IMU data)
Bin/ensemble averaging
Turbulence statistics for ADV data
Instrument Support
Nortek:
AWAC ADCP (current data only, waves in development)
Signature AD2CP (current and waves)
Vector ADV
TRDI:
Workhorse ADCPs (Monitor and Sentinel)
WinRiver output files
VMDAS output files
History
DOLfYN was originally created to provide open-source software for motion correction and turbulence analysis of velocity data collected from ADVs mounted on compliant moorings. It has since been expanded to include reading and analyzing ADCP data.
