Description

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

Acquisition Description

R/V Falkor 160115 McLane log data.

Sampling was conducted using a McLane Pump, 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.

Data version 2:2018-11-20 was an intermediate revision replacing data version 1:2017-09-07 correcting issues with lat/lon values.

Data version 3:2018-12-17 replaces data version 2: 2018-11-20 with changes made after communication with data contributor.
* lat/lon issues corrected. lon values > 360 converted to the equivalent in 180 max format. All long values made negative (verified against cruise track from R2R).
* added columns for max/min filter sizes and ISO_DateTime_UTC.
* Time format was inconsistent and contained HH:MM:00 and HH:MM. Format changed to all HH:MM.
* 24:00:00 value 24:00:00 changed to 23:59
* blank values are displayed as "nd" the default missing data identifier in the BCO-DMO data system.
* target_depth value for station 12 cast MP12 changed from 20 to 21.
* Alternate target_depth values supplied for station 8 cast MP06 by submitter.
* column "depth" removed and target_depth name changed to "depth." There is now only one "depth" column.

Instruments

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.

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.
