Description

Discrete Samples from CTD Casts

Acquisition Description

The Balch lab was involved in sampling a number of variables from the bottle casts,
running an optical surface underway system and it also coordinated the carboy
experiments and dilution experiments on ocean acidification. We sampled from 76 CTD
stations during the cruise, taking water from 8 of the 12 bottles each cast. Water
samples were taken for particulate organic carbon (POC) and particulate organic
nitrogen (PON), particulate inorganic carbon (CaCO3 or PIC), biogenic silica,
coccolithophore counts (processed using the Canada Balsam technique for enumeration
of calcite particles), chlorophyll a extractions (surface bottles always run in
triplicate), and flow-cam samples (for enumeration of net and nanoplankton).

CTD Sea-Bird 911

(more info)

Short Name: CTD SBE 911

Community Standard Description

Generic Description

The Sea-Bird SBE 911 is a type of CTD instrument package. The SBE 911 includes the SBE 9 Underwater Unit and the SBE 11 Deck Unit (for real-time readout using conductive wire) for deployment from a vessel. The combination of the SBE 9 and SBE 11 is called a SBE 911. The SBE 9 uses Sea-Bird's standard modular temperature and conductivity sensors (SBE 3 and SBE 4). The SBE 9 CTD can be configured with 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

(more info)

Short Name: Niskin bottle

Community Standard Description

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.
