DECODR

DECODR is SIO-CalCOFI's comprehensive data processing suite - a Windows program developed by SIO-CalCOFI which has evolved over the years. Originally working with multiple ascii files to generate an IEH and Data Report, DECODR now processes bottle data with corresponding CTD data in station csvs. DECODR does general data processing of the salt, oxygen, chlorophyll, nutrients, and primary productivity analyses. Merging all individual CTD cast bottle data assays into a station csv. DECODR imports corresponding CTD sensor data at the bottle depths. DECODR also creates most of the data products: contour maps (using Surfer), Data Reports, database csvs, & IEHs.

DECODR1511V.exe

Posted by on in DECODR

FIXED - DECODR's DIC import module "Create DIC Database" module (under the Database tab):

 

The problem: the user used to be able to select all stations whether or not there were DIC's sampled or not and get a file with only DIC stations and depths listed.  DECODR was outputting every station depth in the resulting csv for the DIC stations, not just DIC depths.  DECODR1511V only outputs the sta.csv records with the DIC bottle column populated, then inserts the DIC.csv data into the output. Essentially merging the sta.csv bottle and CTD data record with DIC/TA/pH data.

DECODR1511U

Posted by on in DECODR

The latest tweaks of DECODR - version 1511U: when a standard observed level has a mistrip and there are no bottle samples, CESL gives the record a recind "5", meaning CTD-only data. In previous version of DECODR, when interpolated values were desired, interpolated bottle data would be added to this CTD-data-only record (recind 5) without changing the recind to "7".
In version 1511U, which can be used for cruises 1504+, records with recind "5" are treated the same as recind "6", as an extra "bottle". Recind 5 & 6 records are stored but not used in the interpolations but re-inserted into the output files. Note that the recind "7" record generated by the terple routine will be populated with CTD data.

DECODR1511S

Posted by on in DECODR

Fixed: CTD2CSV Data Codes, right side options, will replace data codes for interpolated depths (recind 7; col 79 of sta.csv). The previous version would not replace existing data codes.

DECODR1511R

Posted by on in DECODR

Fixed: The Cruise_ID requested by Ed Weber is consistent now. Established by the first station, the database CRUISE_ID will not change.

Example: 2015-10-28-C-32OC for CalCOFI 1511OC, data collection started on 28 Oct 2015

DECODR1511Q Update

Posted by on in DECODR

The addition of data quality code columns with similar names as the data caused the CSL additions, particularly the Temperature, to not update. DECODR was indexing the data code column, which is normally empty when data are good, instead of the data column itself ie "Temp1Q" instead of "Temp1". Conditionals were added to distinguish the datacode columns from the data, testing for the "Q" in the header.

Use DECODR1511Q for the new CTD.csvs with data quality code columns.
