Description

Methods & Sampling

Dataset acquisition description

Data was logged and collected from Trace Metal Clean Rosette (TMR) deployments during reseach cruise AT50-10. The TMR was deployed on a non-conducting 1/4" Kevlar line and preprogrammed to trip at pre-determined depths on the upcast.

Sampling was conducted using a Trace Metal Clean Rosette (TMR) outfitted with X-Niskin bottles and physicochemical parameters were measured using a mounted Sea-Bird SEACAT 19+. The TMR was deployed on a MASH-2K winch from the UNOLS East Coast Winch Pool.

Instruments

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.

Sea-Bird SBE 19plus V2 SEACAT CTD

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: Sea-Bird SBE 19plus V2 SEACAT CTD

Acronym: Sea-Bird SEACAT 19 Plus V2

Generic Description:

Self-contained self-powered CTD profiler. Measures conductivity, temperature and pressure (Digiquartz sensor) in both profiling (samples at 4 scans/sec) and moored (sample rates of once every 5 seconds to once every 9 hours) mode. Available in plastic or titanium housing with depth ranges of 600m and 7000m respectively. Miniature submersible pump provides water to the conductivity cell. Compared to the previous 19plus, the V2 incorporates an electronics upgrade and additional features, with six differentially amplified A/D input channels, one RS-232 data input channel, and 64 MB FLASH memory.
