Data to accompany the article "Seasonal Variability of
Near-Inertial/Semidiurnal Fluctuations and Turbulence in the
Sub-Arctic North Atlantic"

The .zip files in this archive contain the data files used in the
above Journal of Physical Oceanography paper by Eric Kunze, Ren-Chieh
Lien, Caitlin B. Whalen, James B. Girton, Barry Ma, and Maarten
C. Buijsman.

NISKINEprocessedmicro.zip (45 MB) contains processed microstructure
data used to make the plots in the article. A separate README file
within the .zip file describes its contents. Two PDF files (a data
report and a set of slides presenting results) give additional details.

emapex_files.zip (374 MB) contains all of the individual profiles from
EM-APEX floats in the 2019-2021 NISKINE experiment. There were a total
of 28 deployments (up to 3 per float, labeled by float number along
with "n1," "n2," or "n3") of 15 floats, including both (a) multiple 
deployments and recoveries from the June 2019 R/V Neil Armstrong
"process" cruise and (b) a later long-term observing phase in which 6
floats were left out for up to 2 years of additional data
collection. Files are provided in both ascii (.txt) and Matlab (.mat)
format with the same data. The three 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. Velocity data are computed over 50-second windows slid by 25
seconds, and CTD data are interpolated to the center times of each
window.

2) CTD files (one file per profile ending in -ctd.mat and one in
-ctd.txt) contain the spot-sampled CTD data as directly output by the
SBE-41cp CTD during each profile (resulting in somewhat finer sampling
than the interpolated values in the VEL file).

3) TMS files (one file per *ascending-only* 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.
