Dataset: Hydrography sensor data from trace metal rosette (TMR) casts at 26 stations near coastal Antarctica during RVIB Nathaniel B. Palmer cruise NBP18-01 from Dec 2017 to Feb 2018

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.
