An example of SEACAT data taken from the mooring at 2°S, 156°E during 1992.
University of Hawaii TOGA SEACAT
Data Availability Announcement
Data Updates:
SEACAT data files for University of Hawaii SEACATs deployed in the western equatorial Pacific Ocean from 1991 through 1995 under NSF/NOAA funding for TOGA/COARE are now available via FTP. If you should retreive data from this site, please inform us (seacat@iniki.soest.hawaii.edu). Updates to these files will be made and information concerning the updates will be sent out to those who retreive data from this site and provide contact information. We would also hope to participate in a collaborative effort with those people who choose to analyze this dataset, but at a minimum, we would like to know what you plan to do with these data. A comprehensive database for moored measurements made during TOGA/COARE, containing other SEACAT records as well as data from other instruments, is available though NOAA/PMEL at: http://www.pmel.noaa.gov/coare/coare-data.html.
The SEACAT data files are ASCII files and the link can be downloaded using either the right mouse button or shift+left mouse button in Netscape. You can also open the file and use the "Save as" option in your file menu.
Seacat data files ending with the extension '.fn2' have gone through quality control efforts. Details of the quality control efforts are documented in a file entitled "QC-EDITS" and are also available in a NOAA Technical Report entitled "COARE Seacat Data: Calibration and quality control procedures". A PDF version of this document can be found by clicking here. These efforts have served to identify problematic data and, when possible, to correct these data. Various methods were used to quality control these data including: CTD intercomparisons, near-mooring CTD casts, density stability analyses and analyses conducted during well-mixed periods. Also, when appropriate, temperature drift corrections were applied to these data. Close attention should be paid to these quality control efforts as widely varying salinity drifts were identified by the quality control efforts. Some of these drifts were documented, but could not be corrected for due to a lack of ancillary information to establish a basis for correction. Quality control flags are available for each SEACAT temperature and salinity point in order to aid the data user to identify problematic data and to document the methods used to correct the data.
The SEACAT data files ending with the extension '.dft' have not gone through quality control efforts and simply have had a drift correction applied to the temperature data. SEACAT data files ending with the extension '.avg' also have not gone through quality control efforts and they have not had a drift correction applied to the temperature data. Some SEACATs were lost at sea so post-cruise temperature calibrations could not be made and some instruments were damaged at sea making it impossible to make an accurate post-cruise temperature calibration. The '.dft' and '.avg' files do not have quality control flags for the temperature and salinity data.
SEACAT data files have 5 columns (when quality control flags are available):
- Column 1: Time (Year Day - referenced to January 1, 1992)
- Column 2: Temperature (° C)
- Column 3: Conductivity (S/m)
- Column 4: Salinity (psu)
- Column 5: Quality control flag (1st number is for temperature, 2nd number is for salinity)
The key for the quality control flags is as follows:
- 0 = missing or bad data, data value will be -9.99
- 1 = pre-deployment calibrations used
- 2 = pre- and post-deployment calibrations used (linearly interpolated in time)
- 3 = data adjusted after comparison with co-located CTD casts
- 9 = other (details supplied in documentation)
The following is a list of sensors according to mooring location. The filenames for the sensors are accompanied by their depths (in m) and additional comments when pertinent. Filenames are individually clickable, or you can browse the full directory.
