Sampling QUantitative Internal-wave Distributions

SQUID is the APL-UW contribution to the National Oceanographic Partnership Program's Global Internal Waves Experiment. More info about the NGIW can be found at nopp-giw.ucsd.edu.

(1) For a quick overview of the times and locations of the collected EM-APEX profiles in the SQUID archive, check out the Azure cloud-based SQUID Data Explorer tool.

(2) SQUID data sharing is currently through a set of Dropbox links and folders. Up-to-date aggregated EM-APEX profiles (with some documentation of formats here) are available from the Dropbox folder here. The files in this folder include the following:

allprofs11.mat contains CTD and velocity profiles from all SQUID floats launched between February 2023 and April 2024.

alldiss.mat contains temperature microstructure profiles from all SQUID floats launched between February 2023 and April 2024.

squid_zgrd.mat contains data from the above two files on a common depth grid.

SQUID_all.nc is the NetCDF version of squid_zgrid.mat.

allprofs_squid247.mat contains CTD and velocity profiles from all SQUID floats launched July 2024 or later.

alldiss_squid247.mat contains temperature microstructure profiles from all SQUID floats launched July 2024 or later.

squid247_zgrd.mat contains data from the above two files on a common depth grid.

A NetCDF version of squid247_zgrid.mat will be available soon.

(3) In addition, aggregated files for past EM-APEX experiments are being collected (in subfolders by experiment) here.

(4) And finally, for more streamlined access, the folder here contains .txt and .mat files with updated positions and times of all SQUID float profiles.
