Total spectral count of proteins from R/V Falkor cruise 160115 for the ProteOMZ expedition in the Central Pacific in 2016.

Abstract:

Relative protein abundance data of the upper 1000m water column from the ProteOMZ R/V Falkor expedition. There are 56,577 protein identifications over 103 samples, for ~6 million data points.

Description

These data are part of the Ocean Protein Portal "ProteOMZ" dataset (https://proteinportal.whoi.edu/; Saito et al., 2019).

Data 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.

BCO-DMO Processing

-Date, time, filter min, filter max, lat, lon, and cruise columns were added based on information from the Falkor 160115 Event log and CTD log.
-Column names reformatted to comply with BCO-DMO standards.

Dataset version 3: replaces the earlier data version from date (2018-05-25)
* Values "#N/A" changed to "Unknown" which has a different meaning than blank values. Unknown = "Protein functional and taxonomic annotations are marked as "Unknown" for protein sequences which did not have any significant hits to known reference sequences or motifs in the metagenome annotation database. "
* Event log and McLane pump log were updated to fix lat/lon, date/time issues. Since these were sources of information in this dataset, this dataset is also being updated. See respective "processing notes" sections for these two logs for detailed information about changes to those data sources. event log: https://www.bco-dmo.org/dataset/708384 pump log: https://www.bco-dmo.org/dataset/708495
* ISO_DateTime_UTC timestamp added from Date and time columns in the McLane log dataset. Date and time columns were HST time zone so 10 hours were added to make the time in UTC.
* columns for max and min pump filter size added (min 0.2 max 3.0).
* some station and target depths for station and target depth combinations did not exist in the Mclane pump log so the missing values were added to the mclane pump log. The following columns in this dataset come from the pump log: cruise, cast, date, time, lat, lon, depth (ISO_DateTime_UTC is derived from local date and time). Where there were two matched casts in the pump log for a station and target depth, the first cast for the station was used. The only differences between the two possible casts were the date/time columns.

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.
