Methods & Sampling

Dataset acquisition description

Suspended particles were collected at 5 different stations along a North Pacific transect between Hawaii and Alaska. Samples were collected on 142 mm diameter Glass Fiber Filters (GFF) using McLane Pumps. Particulate Inorganic Carbon (PIC) content was measured by acidifying a subsample of the GFF filter and measuring total CO2 released on a Picarro gas concentration analyzer. Total Particulate Carbon (PC) and Particulate Nitrogen (PN) were analyzed by burning a subsample of the GFF on an Elemental Analyzer (EA).

Data Processing Description

Dataset Processing Description

BCO-DMO processing:
- Converted latitude and longitude to decimal degrees.
- Created column for ISO 8601 formatted times (UTC/GMT timezone)
- Rounded column values to submitter preference
- Modified parameter (column) names to conform with BCO-DMO naming conventions.
No spaces, hyphens, commas, parentheses, or Greek letters.
The only chararacters allowed are A-Z, a-z, 0-9, and underscores.

Instruments

Cavity enhanced absorption spectrometers

Supplied Name: Picarro Cavity Ring-Down Spectroscopy Gas Analyzer (G2131-i)

Supplied Description:

Particulate Inorganic Carbon (PIC) content was measured by acidifying a subsample of the GFF filter and measuring total CO2 released on Picarro

Instrument Type

Generic Name: Cavity enhanced absorption spectrometers

Acronym: CEAS

Generic Description:

Instruments that illuminate a sample inside an optical cavity, typically using laser light, and measure the concentration or amount of a species in gas phase by absorption spectroscopy. Techniques include cavity ring-down spectroscopy (CRDS) and integrated cavity output spectroscopy (ICOS).

CO2 Analyzer

Supplied Name: Picarro Cavity Ring-Down Spectroscopy Gas Analyzer (G2131-i)

Supplied Description:

Particulate Inorganic Carbon (PIC) content was measured by acidifying a subsample of the GFF filter and measuring total CO2 released on Picarro

Instrument Type

Generic Name: CO2 Analyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/382/

Generic Description:

Measures atmospheric carbon dioxide (CO2) concentration.

Elemental Analyzer

Supplied Name: Costech ECS4010 CHNSO Elemental Analyzer

Supplied Description:

Total Particulate Carbon (PC) and Particulate Nitrogen (PN) were analyzed by burning a subsample of the GFF on Elemental Analyzer (EA).

Instrument Type

Generic Name: Elemental Analyzer

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/LAB01/

Generic Description:

Instruments that quantify carbon, nitrogen and sometimes other elements by combusting the sample at very high temperature and assaying the resulting gaseous oxides. Usually used for samples including organic material.

McLane Pump

Supplied Description:

Samples were collected on Glass Fiber Filters using Mclane Pumps

Instrument Type

Generic Name: McLane Pump

Generic Description:

McLane pumps sample large volumes of seawater at depth. They are attached to a wire and lowered to different depths in the ocean. As the water is pumped through the filter, particles suspended in the ocean are collected on the filters. The pumps are then retrieved and the contents of the filters are analyzed in a lab.
