Description

Methods & Sampling

Seawater was obtained at sea from 10-L Niskin bottles on a CTD rosette. Sample volumes of 1.1 L were collected in dark polyethylene bottles, and the contents were filtered onto precombusted 25-mm GF/F filters. Filters were folded into precombusted packets of aluminum foil and frozen in liquid nitrogen. Samples were later stored in a -80°C freezer, and acidified and dried before analysis. Analyses were conducted at the Analytical Facility, Marine Science Institute, UCSB on a Finnigan Delta Plus Advantage continuous flow system with Costech ECS 4010 elemental combustion.

Instruments

CHN Elemental Analyzer

Supplied Name: Costech ECS 4010

Supplied Description:

Analyses were conducted at the Analytical Facility, Marine Science Institute, UCSB on a Finnigan Delta Plus Advantage continuous flow system with Costech ECS 4010 elemental combustion. The ECS 4010 Nitrogen / Protein Analyzer is an analytical platform for CHNSO elemental analysis and Nitrogen / Protein determination.

Instrument Type

Generic Name: CHN Elemental Analyzer

Acronym: CHN_EA

Generic Description:

A CHN Elemental Analyzer is used for the determination of carbon, hydrogen, and nitrogen content in organic and other types of materials, including solids, liquids, volatile, and viscous samples.

Isotope-ratio Mass Spectrometer

Supplied Name: Finnigan Delta Plus Advantage

Supplied Description:

Analyses were conducted at the Analytical Facility, Marine Science Institute, UCSB on a Finnigan Delta Plus Advantage continuous flow system with Costech ECS 4010 elemental combustion. The Finnigan DELTAplusAdvantage is a stable isotope ratio MS for dual-inlet and continuous-flow applications.

Instrument Type

Generic Name: Isotope-ratio Mass Spectrometer

Acronym: IR Mass Spec; IRMS

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB16/

Generic Description:

The Isotope-ratio Mass Spectrometer is a particular type of mass spectrometer used to measure the relative abundance of isotopes in a given sample (e.g. VG Prism II Isotope Ratio Mass-Spectrometer).

Niskin bottle

Supplied Description:

Seawater was obtained at sea from 10-L Niskin bottles on a CTD rosette.

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.
