Data to accompany the article "Destratification and Restratification of the Spring Surface Boundary-Layer in a Subtropical Front" The .zip files in this archive contain the data files used in the above Journal of Physical Oceanography paper by Eric Kunze, John B. Mickett, and James B. Girton. smileprocesseddata.zip contains processed data used to make the plots in the article. A separate readme file within the .zip file describes its contents. emapex_profiles.zip contains all of the individual profiles from EM-APEX floats at the third site occupied in the 2017 SMILE experiment on the R/V Sikuliaq. Files are provided in both ascii (.txt) and Matlab (.mat) format with the same data. The two data file varieties are: 1) VEL files (one file per profile ending in -vel.mat and one in -vel.txt) contain the CTD and EF velocity profiles as well as GPS positions. Headers in the text files include single-valued variables, along with a list ('vars') of variables in the columns after the header. 2) TMS files (one file per profile ending in -tms.mat and one in -tms.txt) contain the Temperature Microstructure profiles in the form of binned spectra from the two sensors. Frequency bins are given in the .txt file's header and resulting spectra from each 20 second window (slid by 10 seconds) are reported on each line. Additional info or clarification about the files and processing used in the paper can be obtained by contacting Eric Kunze (kunze@nwra.com) or James Girton (girton@uw.edu).
