Description

Hydrography data from Metzyme cruise (KM1128) collected using the Trace Metal Rosette (TMR).

Methods & Sampling

Data were collected using the Trace Metal Rosette ((TMR), Sea-Bird SEACAT 19+).

Note that the ship's CTD package (Sea-Bird SBE 911+) was also used for sampling at some stations. See the CTD dataset for these related data.

Data Processing Description

BCO-DMO Processing:
- modified parameter names to conform with BCO-DMO naming conventions (removed spaces, replaced "/" with underscores);
- replaced blanks (missing data) with "nd";
- corrected all years of "0011" to "2011".

Supplied Name:

Supplied Description:

Instrument Type

Generic Name: CTD Sea-Bird SBE SEACAT 19plus

Acronym: Sea-Bird SEACAT 19 Plus

Generic Description:

Self contained self powered CTD profiler. Measures conductivity, temperature and pressure in both profiling (samples at 4 scans/sec) and moored (sample rates of once every 5 seconds to once every 9 hours) mode. Available in plastic or titanium housing with depth ranges of 600m and 7000m respectively. Minature submersible pump provides water to conductivity cell.

Parameters

Date and time formats are described in python strftime() syntax.
