HYDROSCAT
Deployment
- The Hydroscat is deployed on the CTD package and follows CTD deployment protocols.
Data Processing
- Hydroscat data is processed using a combination of HOBILabs software processing tools and standard BBOP processing scripts. The HOBILabs software module converts raw Hydroscat data into standard engineering units and outputs a flat ascii file. The flat ascii files are then converted to *.lcd and further processed using BBOP scripts The data processing procedure is outlined below.
- On the Hydroscat laptop open the Hydroscat software.
- From the menu bar select File and then select Open Raw Data File.
- Select the raw data file to be converted. The file will have the form h`cruise_date’`station’.log
- The software will convert the raw data files into standard engineering units.
- Once all the files have been converted, transfer them, via FTP, to /home/data65/pb/HYDROSCAT/`cruise’
- The remaining processing steps occur in UNIX.
- Logon to Simbios.
- Make sure that the correct Display environment is set.
- Type: setenv DISPLAY terminal_name.crseo.ucsb.edu:0
- Change directories to the folder containing the Hydroscat data.
- At the prompt type: hydro_mklcd.s
- This will start Matlab.
- At the Matlab prompt type: hydro_mklcd
- The software will ask a series of question about station location and environmental conditions. This information can be found on the cast sheets.
- Run hydro_mklcd for each file.
- Once all files have been ran through the hydro_mklcd script, next pick the upcast/downcast portion of each cast. Each file will automatically be loaded into Matlab.
- Once the upcast/dpwncast portions have been selected, the files will automatically be averaged and binned using standard BBOP functions.
Plotting
- At the prompt type: bb_spectra
- Print the figure. Once the figure has been printed type: close and then clear.
- Run bb_spectra for each file in the list.
- Next run bb_depth for the same files.
