Description

These data are part of the Ocean Protein Portal "Ross Sea Net Tow (Bender)" dataset version 1 (https://proteinportal.whoi.edu/; Saito et al., 2020).

Methods & Sampling

Dataset acquisition description

Sampling was conducted with a 20 micron plankton net on 12/30/2005 at about 1am (local time), near station 137, was extracted for total protein using an SDS detergent method followed by tube gel purification, reduction, alkylation, and tryptic digestion and analyzed on a Thermo Orbitrap Fusion using 2-dimensional separation scheme to maximize metaproteome depth. Detailed methods available in Bender et al. 2018.

Organism identifier (LifeSciences Identifier, LSID):
Phaeocystis antarctica, urn:lsid:marinespecies.org:taxname:341585

Data Processing Description

Dataset Processing Description

Mass spectra from 2D LC-MS was peptide-to-spectrum matched using the SEQUEST algorithm within Proteome Discoverer software, followed by spectral counting with Proteome Software's Scaffold software using the FASTA sequence file generated from Phaeocystis culture transcriptome study. Data processing documented in Bender et al. 2018.
