Data Processing Description

Raw data was processed using Seasave software version 7.21e. BCO-DMO retrieved the processed data from the ship's hard drive and made the following edits to the bottle (.btl) files:
- Changed parameter names to conform to BCO-DMO conventions;
- Converted latitude and longitude from degrees and decimal minutes to decimal degrees;
- Added cast, date, time_start, lat_start, lon_start from the CTD file headers;
- Separated day_gmt, month_gmt, year, and time_gmt into separate columns from the original Date and Time fields.
- Bottle file '20101052' (bottle data from cast 52),contained only invalid/undecipherable values. Possible instrument or processing failure, or data file corruption. BCO-DMO replaced these data with 'nd' to indicate 'no data'.

Instruments

Niskin bottle

Supplied Description:

Instrument Type

Generic Name: Niskin bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0412/

Generic Description:

A Niskin bottle (a next generation water sampler based on the Nansen bottle) is a cylindrical, non-metallic water collection device with stoppers at both ends. The bottles can be attached individually on a hydrowire or deployed in 12, 24, or 36 bottle Rosette systems mounted on a frame and combined with a CTD. Niskin bottles are used to collect discrete water samples for a range of measurements including pigments, nutrients, plankton, etc.
