Description

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

Methods & Sampling

R/V Falkor 160115 event log data.

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

Data 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

Instruments

CTD - profiler

Supplied Name: CTD

Supplied Description:

Used for water sampling

Instrument Type

Generic Name: CTD - profiler

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

Generic 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. It permits scientists to observe the physical properties in real-time via a conducting cable, which is typically connected to a CTD to a deck unit and computer on a 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 term applies to profiling CTDs. For fixed CTDs, see https://www.bco-dmo.org/instrument/869934.

McLane Pump

Supplied Name: McLane

Supplied Description:

Used for water sampling

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.

Phytoplankton Net

Supplied Name: Net

Supplied Description:

Used for all net tows

Instrument Type

Generic Name: Phytoplankton Net

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/22/

Generic 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.

Pump surface

Supplied Name: Surface pump

Supplied Description:

Used for water sampling

Instrument Type

Generic Name: Pump surface

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/31/

Generic 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.

Trace Metal Bottle

Supplied Name: TMR

Supplied Description:

Trace Metal Clean Rosette

Instrument Type

Generic Name: Trace Metal Bottle

Acronym: TM Bottle

Community Identifier: http://vocab.nerc.ac.uk/collection/L05/current/30/

Generic Description:

Trace metal (TM) clean rosette bottle used for collecting trace metal clean seawater samples.
