Upper Water Column Data Visualization : Upper Water Column Data holdings inventory This page last changed on May 26, 2010 by mccann. ### How much data do we have? #### Summary
Data Category | CDM dataType | Period of observations | Frequency of observations | Size on disk | # of records | # of parameters | Size of record
--- | --- | --- | --- | --- | --- | --- | ---
ROVCTD | Trajectory | 1988 to 2010 | 15-second | 0.40 GB | 3 Million time records | 16 | 130 bytes 4
Mooring 1 | Station& StationProfile | 1989 to 2010 | 10-minutes and hourly | 1.03 GB | 4.5 Million time records | 20 | 80 to 4800 bytes 2
AUVCTD | Trajectory | 2003 to 2009 (269 surveys) | 2-second gridded | 0.45 GB | 5.6 Million time records | 10 | 80 bytes 3
UCTD | Trajectory |  |  |  |  |  |
PCTD | Profile |  |  |  |  |  |
BCTD | Profile | 1988 to 2010 | Nominally fortnightly |  |  |  |
Bottom line: We have just about 2 GB, certainly less than 10 GB. What we are dealing with can fit on a modern laptop. Notes: See Mooring Data Details table below Record size for mooring data depends on number of profile depths in the record, up to 60 levels for ADCP data Double precision (8-bytes) used for AUVCTD NetCDF data #### Mooring Data Details - from THREDDS Data Server (TDS) aggregation of QC'ed data from the netCDF data archive
