BCO-DMO Processing Notes
- Generated from original file Final_CDT_Bottle_data.txt

Comments from original data file by BH:
CTD bottle data from SOGasEx cruise, Feb-April 2008 aboard RV Ron Brown.
STAT in this file represents the CTD station number followed by a 1.
e.g. STAT 11 is CTD station 1, STAT 511 is CTD station 51.

SAMP here is the niskin number appended with a leading 1.
SAMP 101 is niskin 1. SAMP 124 is niskin 24.

Ox is O2 data calculated from SBE electrode readings.
O2 is preliminary winkler data provided by R. Hamme.
Final O2 data is provided with the other water chemistry data sets.

Flags following S0 and O2 columns indicate data quality.
Flag = 2 means good;
Flag = 3 means questionable;
Flag = 4 means bad;
Flag = 9 means no data.

'No data' is written as -9 in original file.
BCO-DMO Note: 'No data' converted to BCO-DMO standard of 'nd' in processed file

Station 91 samples 115-124 have bad OX (CTD O2) data but are not flagged.

BCO-DMO Edits
- parameter names modified to conform to BCO-DMO convention
- event, station, date, time, lon, lat inserted from CTD headers file
- '-9' (No data flag in original) changed to 'nd'
- decimal places padded as appropriate for consistency

Instrument Type

Generic Name: CTD Sea-Bird SBE 911plus

Acronym: CTD SBE 911plus

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0058/

Generic Description:

The Sea-Bird SBE 911 plus is a type of CTD instrument package for continuous measurement of conductivity, temperature and pressure. The SBE 911 plus includes the SBE 9plus Underwater Unit and the SBE 11plus Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 plus and SBE 11 plus is called a SBE 911 plus. The SBE 9 plus uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 plus and SBE 4). The SBE 9 plus CTD can be configured with up to eight auxiliary sensors to measure other parameters including dissolved oxygen, pH, turbidity, fluorescence, light (PAR), light transmission, etc.). more information from Sea-Bird Electronics
