This is the public archive for ADCP data collected with SWIFT drifters during the 'Langmuir Circulation' Office of Naval Research Departmental Research Initiative (LC-DRI) field experiment, conducted between March 19th and April 6th, 2017 in the Southern California Bight 40 km west of Catalina Island. SWIFTs were deployed and recovered from the R/V R.G. Sproul during cruise SP1709 (Cruise DOI: 10.7284/907464). SWIFTs were deployed during storms with wind speeds up to 20 m/s and sampled strong diurnal warm layers during weaker wind periods.
SWIFT drifters float at the ocean surface and collect measurements of near-surface velocity in a surface following reference frame using high-resolution acoustic Doppler current profilers (ADCPs), Nortek Signature 1000s. The ADCP data in this archive are subject to minimal quality control onboard the SWIFTs but are otherwise unprocessed other than conversion from binary. This 'raw' data is available for turbulence estimates. The .zip file contains .mat files with data and a READ ME (.txt file) describing the data format. Processing codes for the SWIFT-mounted Signature 1000s can be found here: https://github.com/SASlabgroup/SWIFT-codes/tree/master/Signature.
Matlab is required to open the data files (.mat files) included in this archive.
