SeaSoar Data for Salinity Spiking
The data record for the original salinity spiking project was a bit
short to get a crisp result from the coherence analysis. As an
alternative, you may wish to look at longer records from more recent
SeaSoar cruises conducted by Shaun Johnston and Dan Rudnick. Data
come from two projects:
The raw 24-Hz data are in binary format, and you will need to make use
of the m-files provided to read the binary files into matlab.
Shaun also has m-files for his despiking method, which you might
wish to examine after you've made a reasonable attempt to reduce the salinity
spiking. Each ~2 hour raw file is ~5 MB.
- An experiment to look at the impact of including a pump on the
SeaSoar in an effort to reduce salinity spiking.
- A survey of an offshore front with lots of interleaving (which
might be expected to cause lots of salinity spiking).
The tar file sal_spike_m_files.tar
contains the following scripts:
Here's an example of the arguments to pass to allread2.m:
'../deployment2'; % directory containing raw data
'FLT_DAT'; % filename prefix
'01C'; % beginning filename suffix
'01C'; % ending filename suffix
cfgload('830_0806.cal'); % configuration structure
Data files are called FLT_DAT.???. The FLT_DAT files are numbered
in hex. For the front survey you want 030 to 05C. For the
pumped/unpumped it's 144 to 14D.
