Description

Data from carboy experiments conducted aboard the vessels during the two Great Southern Coccolithophore Cruises - MV1101 and RR1202.

CarBoy and Dilutution Experiments Location Map

Methods & Sampling

Water collected from a single CTD cast at 4 Stations, approximately 5m depth.

8 x 20l Carboys filled with raw seawater

4 x 20l Carboys filled with 0.2µm filtered seawater

4 treatments incubated at surface temperature/light levels (on deck with surface seawater circulated through incubators) at 380, 500, 750, and 1200 ppm CO₂(premixed Air/CO₂ continuously bubbled in each carboy). Each treatment consists of 2 whole water and 1 fsw carboy.

Carboys sampled at T0, 24h, 48h, and 72 hours for Chlorophyl a (Chl a), Particulate Inorganic Carbon (PIC), Biogenic Silica (BSi), Birefringent Cell and Coccolith counts, Dissolved nutrients (NO₃, PO₄, SiO₄, NO₂, NH₄), Dissolved Inorganic Carbon (DIC), and Total Alkalinity (TA).

Data Processing Description

BCO-DMO Processing Notes
- Generated from original files "GB1 carboy data.xlsx" and "GB2 carboy data.xlsx" contributed by Bruce Bowler
- Parameter names edited to conform to BCO-DMO naming convention found at Choosing Parameter Name
- CruiseId, CTD Station, Cast, Date, Lat and Lon inserted from CTD station data
- Experiment Id inserted into data (GB1_CB1, GB2_CB1, etc.)
- "nd" (no data) inserted into blank cells
- blank rows removed
- POC and PON inserted into GB1 data for compatibility with GB2 data (all GB1 data set to "nd")
- parameters: eb lith1:ml, eb lith2:ml, eb lith3:ml, eb tot lith:ml, eb lith area:ml, eb cell+agg area:ml removed per instruction from Bruce Bowler

Instruments

CTD Sea-Bird SBE 911plus

Supplied Name:

Supplied Description:

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

Niskin bottle

Supplied Name:

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.
