The files below are from the OS150 under narrow-band mode, using 4m bins and
7m surface blanking. The transducer depth was set to 8m. The ensemble length
was 5 minutes.
I generated two data formats: the one I traditionally use, and one that Dan
Torres generates. My format only includes the finally processed zonal and
meridional components, and usually consists of just one file that grows over
the course of the cruise. Additional, section-specific products (files) like the
projection onto section lines and rotation into cross/along- section components
are presented in Dan's format only.
The data format is decribed here.

For completeness (and mostly for myself), I include the most recently
updated version of the full dataset:
hly1803_os150_edtmdt.mat (Frank's format).
The letters "edtmdt" indicates the level of processing:
- "edt": the data were manually/visually edited;
- "m": on the rare occasion that the OS150 was ice blocked on station
but the OS75 was not, OS75 data were interpolated to fill the hole
- "dt": the baroctropic tide has been removed.
This .mat file includes the matrix "txy" with columns of time, longitude,
and latitude. Time is in "decimal days", which counts the day of the year
with noon on January 1 being decimal day 0.5. To convert decimal days to
matlab's time format, add the following offset:
mat_time = txy(:,1) + datenum(2018,1,1);
The resulting vector "mat_time" can be converted to [year month day hour min sec]
using matlab's "datevec":
mat_time_str = datevec(mat_time);
