Data Processing Description

BCO-DMO Processing Notes
- Generated from original .xlsx file "EPZT_TGT303_Event_Log_ed.xlsx" contributed by MCJ
- Edits made by MCJ incorporated in v30Oct2014 version
- Corrections made to misc, obvious navigation errors using R2R cruisetrack navigation
- "nd" no data inserted into blank cells
- date reformatted to BCO-DMO standard of YYYYMMDD
- time reformatted to BCO-DMO standard of HHMM
- ISO date/time fields inserted
- latitude in decimal degrees generated from latitude degs, mins (latitude deg, mins preserved)
- longitude in decimal degrees generated from longitude degs, mins (longitude deg, mins preserved)
- commas "," in text columns converted to semicolons ";"
- misc reformatting of location column data for standardization (blanks removed)
- Parameter names edited to conform to BCO-DMO naming conventions.
