Description

Table of CTD and PUMP Cast Events for GT11/KN204-01 A/B
Summary of activity at each cast event - station. cast, event, type, date, time, Start, Mid, End, etc

Methods & Sampling

(none)

Data Processing Description

BCO-DMO Processing Notes
- Generated from original text files "gt11_casttimes-bot[end][in][out][start].txt" contributed by Ed Boyle
- Pump events generated from spreadsheet "GT11_QCd_PumpLog_Summary.xls, Sheet: flowmeter output & pump summary" contributed by Ed Boyle
- Date reformatted to YYYYMMDD
- Time reformatted to HHMMSS
- Original Rosette type in "comments" field (GT-C or SIOR) combined with dep_type field for CTD casts
- Lat/Lons for Pump events added from cruise track data
- Column added for "event" or activity such as Start, End, etc
- "nd" (no data) value inserted in blank cells
- Additional PUMP events not in the Boyle spreadsheet added by BCO-DMO staff from pump cast sheets (10Oct2012/srg)

Parameters

Date and time formats are described in python strftime() syntax.

Supplied Name	Supplied description	Supplied Units	Standard Name
station_GEOTRC	GEOTRACES station number; ranges from 1 through 12 for KN199-04 and 1 through 24 for KN204-01. Stations 7 and 9 were skipped on KN204-01. Originally submitted as 'station', this parameter name has been changed to conform to BCO-DMO's GEOTRACES naming conventions.	integer	station
cast_GEOTRC	Cast identifier, numbered consecutively within a station. Originally submitted as 'cast_no', this parameter name has been changed to conform to BCO-DMO's GEOTRACES naming conventions.	integer	cast
event_GEOTRC	Unique identifying number for US GEOTRACES sampling events; ranges from 2001 to 2225 for KN199-04 events and from 3001 to 3282 for KN204-01 events. Originally submitted as 'gt_event', this parameter name has been changed to conform to BCO-DMO's GEOTRACES naming conventions.	integer	exp_id
activity	Event/Activity - Start; Submerge; Bot; Emerge; End. (name changed from 'event' to 'activity' on 06 March 2013 to be consistent with the GT10 CTD and pump cast events dataset.)	text	activity_and_comments
