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.
