Methods & Sampling

Dataset acquisition description

Data Processing Description

Dataset Processing Description

The raw mass spectra files were searched against SEQUEST within Proteome Discoverer v2.2 software. Processed files were then loaded into Proteome Software and protein and peptide reports as well as and fasta files were exported. The files were modified slightly to map to the Protein Portal data model for submission to BCO-DMO. The peptide report was too large to work with within Excel and was modified in Pandas/Python to produce a CSV file.

Instruments

Alpkem RFA300

Supplied Name: Alpkem Autosampler

Supplied Description:

Used in nutrient analysis

Instrument Type

Generic Name: Alpkem RFA300

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0414/

Generic Description:

A rapid flow analyser (RFA) that may be used to measure nutrient concentrations in seawater. It is an air-segmented, continuous flow instrument comprising a sampler, a peristaltic pump which simultaneously pumps samples, reagents and air bubbles through the system, analytical cartridge, heating bath, colorimeter, data station, and printer. The RFA-300 was a precursor to the smaller Alpkem RFA/2 (also RFA II or RFA-2).

CTD Sea-Bird

Supplied Name: SeaBird SBE19 CTD

Supplied Description:

Used for water sampling

Instrument Type

Generic Name: CTD Sea-Bird

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/130/

Generic Description:

Conductivity, Temperature, Depth (CTD) sensor package from SeaBird Electronics, no specific unit identified. This instrument designation is used when specific make and model are not known. See also other SeaBird instruments listed under CTD. More information from Sea-Bird Electronics.

Technicon AutoAnalyzer II

Supplied Description:

Used to measure phosphate and ammonium

Instrument Type

Generic Name: Technicon AutoAnalyzer II

Community Identifier: http://vocab.nerc.ac.uk/collection/L22/current/TOOL0291/

Generic Description:

A rapid flow analyzer that may be used to measure nutrient concentrations in seawater. It is a continuous segmented flow instrument consisting of a sampler, peristaltic pump, analytical cartridge, heating bath, and colorimeter. See more information about this instrument from the manufacturer.
