Dataset Description

R/V Falkor 160115 event log from the ProteOMZ expedition in the Central Pacific during 2016.

Acquisition Description

R/V Falkor 160115 event log data.

Sampling was conducted using a CTD, Trace Metal Clean Rosette, McLane Pump, Net Tow, or Surface Pump.

Processing Description

BCO-DMO Data Processing Notes:
- reformatted column names to comply with BCO-DMO standards.
- replaced spaces in column names with underscores.
- removed special characters from column names.
- removed units from column names
- converted longitude values to negative (W)
- revised station 1 and 3 latitudes

Data version 2: 2018-11-19 replaces data version 1:
* revised station 1 and 3 lats to corrected and positive values and changed all lons to negative (W).

Data version 3: 2018-12-07 replaces version 2: 2018-11-19
* UTC Date and DateTimes in ISO format added from local date and time columns (HST = UTC-10).
* Time value 5;00 changed to 5:00
* values "blank" changed to empty cells
* commas in comments changed to semicolons in order to support correct export as csv from the BCO-DMO data system.
* all lat/lons converted to abs(180) format. Checked by plotting over R2R cruise track.
* values with word "blank" changed to empty cells for consistency
* Mclane pump at station 7 changed from McLane-6 to McLane-5

Dataset-specific Instrument Name
Generic Instrument Name
CTD profiler
Dataset-specific Description
Used for water sampling
Generic Instrument Description
The Conductivity, Temperature, Depth (CTD) unit is an integrated instrument package designed to measure the conductivity, temperature, and pressure (depth) of the water column. The instrument is lowered via cable through the water column and permits scientists observe the physical properties in real time via a conducting cable connecting the CTD to a deck unit and computer on the ship. The CTD is often configured with additional optional sensors including fluorometers, transmissometers and/or radiometers. It is often combined with a Rosette of water sampling bottles (e.g. Niskin, GO-FLO) for collecting discrete water samples during the cast. This instrument designation is used when specific make and model are not known.

Dataset-specific Instrument Name
Generic Instrument Name
Phytoplankton Net
Dataset-specific Description
Used for all net tows
Generic Instrument Description
A Phytoplankton Net is a generic term for a sampling net having mesh size of 150 microns or less that is used to collect phytoplankton. It is used only when detailed instrument documentation is not available.

Dataset-specific Instrument Name
Generic Instrument Name
Trace Metal Bottle
Dataset-specific Description
Trace Metal Clean Rosette
Generic Instrument Description
Trace metal (TM) clean rosette bottle used for collecting trace metal clean seawater samples.

Dataset-specific Instrument Name
Surface pump
Generic Instrument Name
Pump surface
Dataset-specific Description
Used for water sampling
Generic Instrument Description
A source of uncontaminated near-surface seawater pumped onto the deck of the research vessel that can be sampled and analyzed. This pumped seawater supply is from an over-the-side pumping system, and is therefore different from the vessel underway seawater system.

Dataset-specific Instrument Name
Generic Instrument Name
McLane Pump
Dataset-specific Description
Used for water sampling
Generic Instrument 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.

Project Information

The ProteOMZ Expedition: Investigating Life Without Oxygen in the Pacific Ocean (ProteOMZ (Proteomics in an Oxygen Minimum Zone))

Coverage: Central Pacific Ocean (Hawaii to Tahiti)

From Schmidt Ocean Institute's ProteOMZ Project page: Rising temperatures, ocean acidification, and overfishing have now gained widespread notoriety as human-caused phenomena that are changing our seas. In recent years, scientists have increasingly recognized that there is yet another ingredient in that deleterious mix: a process called deoxygenation that results in less oxygen available in our seas. Large-scale ocean circulation naturally results in low-oxygen areas of the ocean called oxygen deficient zones (ODZs). The cycling of carbon and nutrients – the foundation of marine life, called biogeochemistry – is fundamentally different in ODZs than in oxygen-rich areas. Because researchers think deoxygenation will greatly expand the total area of ODZs over the next 100 years, studying how these areas function now is important in predicting and understanding the oceans of the future. This first expedition of 2016 led by Dr. Mak Saito from the Woods Hole Oceanographic Institution (WHOI) along with scientists from University of Maryland Center for Environmental Science, University of California Santa Cruz, and University of Washington aimed to do just that, investigate ODZs. During the 28 day voyage named “ProteOMZ,” researchers aboard R/V Falkor traveled from Honolulu, Hawaii to Tahiti to describe the biogeochemical processes that occur within this particular swath of the ocean’s ODZs. By doing so, they contributed to our greater understanding of ODZs, gathered a database of baseline measurements to which future measurements can be compared, and established a new methodology that could be used in future research on these expanding ODZs.
