Methods & Sampling

Samples were collected by Niskin bottle and transferred into 2.2-L amber polyethylene bottles. They were then immediately vacuum filtered through pre-combusted GF/F filters. Filters were covered in pre-combusted aluminum foil and placed in cryovials. They were then placed in a -80C filter until they could be dried in a drying oven for shipping. Post-cruise, samples were acidified with fuming HCl, then thoroughly dried again and put into tin capsules. Samples were analyzed by isotope ratio mass spectrometer at the U.C. Davis Stable Isotope Facility.

Data Processing Description

BCO-DMO Processing:
- changed date format to yyyy-mm-dd;
- rounded lat and lon to 4 decimal places;
- rounded POC, PN, d13C, and d15N to 2 decimal places;
- renamed fields.

Instruments

Isotope-ratio Mass Spectrometer

Supplied Name:

Supplied Description:

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 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.
