Abstract:

This dataset provides the trace metal rosette (TMR) hydrography data from the Amundsen and Ross Seas, including from Terra Nova Bay, collected onboard the R/V Nathaniel B. Palmer as part of the Cobalamin and Iron Co-Limitation of Phytoplankton Species (CICLOPS) expedition from December 11, 2017 to March 3, 2018. Sensor information and calibration dates are available in the report 'NBP1801_Data_Report.pdf' available as a supplemental file.

Methods & Sampling

Sensors were deployed on a titanium trace metal rosette (TMR) in tandem with trace metal clean bottle samples during the RVIB Nathaniel B. Palmer cruise (NBP18-01) from December 2017 to February 2018 in coastal Antarctica. TMR casts were performed at 26 stations in the Amundsen Sea, Ross Sea and Terra Nova Bay. Parameters collected include pressure, temperature, conductivity, oxygen, fluorescence, beam transmission, PAR, and salinity.

The profiles in the dataset are from the up-cast of the TMR cast. More information on sensor data acquisition and processing can be found in "Data Report NBP18-01" from the United States Antarctic Program prepared by Matt Pullen and Bryan Chambers (see Supplemental Docs section). Trace metal rosette sensors are detailed on p.29.

For all duplicate sensors, the primary sensor was used for temperature and conductivity, and the secondary sensor was used for oxygen in the final hydrography dataset.

Problem report:
The PAR sensor was only included on the TMR beginning at station 35.

Data Processing Description

The profiles in the dataset are from the up-cast of the TMR cast. More information on sensor data acquisition and processing can be found in "Data Report NBP18-01" (see Supplemental Docs section)

BCO-DMO Processing

- converted latitude and longitude to decimal degrees (from degrees, decimal mins)
- converted Date to YMD format
- added conventional header with dataset name, PI name, version date
- modified parameter names to conform with BCO-DMO naming conventions
