Description

Concentrations and stable isotope abundances of particulate organic carbon (POC) and particulate organic nitrogen (PON). Samples were collected on the MV1008 cruise in the Costa Rica Dome (CRD) region of the Eastern Tropical Pacific Ocean.

Methods & Sampling

Dataset acquisition description

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.
