PNE Data and Products

Moored buoy data is quality controlled and distributed by PMEL's TAO Project Office.

2013b PNE Cruise Data

CTD data have been corrected to bottle salinity and oxygen measurements, and are accurate to WOCE standards. They can be downloaded here.

2013a PNE Cruise Data

CTD data have been corrected to bottle salinity and oxygen measurements, and are accurate to WOCE standards. They can be downloaded here.

2011 PNE Cruise Data

CTD data have been corrected to bottle salinity and oxygen measurements. Due to a failure of the Autosal on the Ronald H. Brown, salinity values were not reliably calculated for the first five casts; all casts were calibrated according to salinometer results from samples drawn at the final station, and the salinity accuracy is likely not to WOCE standards. Oxygen accuracy was unaffected and is to WOCE standards. The data can be downloaded here.

2010 PNE Cruise Data

CTD data have been corrected to bottle salinity and oxygen measurements, and are accurate to WOCE standards. They can be downloaded here.

2009 PNE Cruise Data

CTD data have been corrected to bottle salinity and oxygen measurements, and are accurate to WOCE standards. They can be downloaded here.

2008 PNE Cruise Data

PNE08 data from the R/V Antea is calibrated, but may be of lower quality than typical PNE cruises as the samples were shipped to AOML and processed over a month after the end of the cruise The data can be downloaded here.

2007 PNE Cruise Data

XBT data were recalculated using the old (code 51) drop rate, which gave better results when compared to CTD data.

CTD data have been corrected to bottle salinity and oxygen measurements, and are accurate to WOCE standards.

TSG data were compared to CTD casts at 5m water depth, the average depth of the water intake on the Ronald H. Brown. Temperatures were found to match well, with a mean offset of 0.02 C (positive: CTD warmer). This offset was removed from the data below. The standard deviation of the adjusted TSG temperature from CTD values is 0.067 C. TSG salinity was offset from CTD salinity by a mean of 0.056 psu (positive: CTD saltier). This offset was also removed from the data below. The standard deviation of the adjusted TSG salinity from CTD values is 0.027 psu.

2006 PNE Cruise Data

XBT data were recalculated using the old (code 51) drop rate, which gave better results when compared to CTD data.
CTD data have been corrected to bottle salinity and oxygen measurements, and are accurate to WOCE standards.
TSG data were compared to CTD casts at 5m water depth, the average depth of the water intake on the Ronald H. Brown. Temperatures were found to match well, with a mean offset of 0.017 C (positive: CTD warmer). This offset was removed from the data below. The standard deviation of the adjusted TSG temperature from CTD values is 0.021 C. TSG salinity was offset from CTD salinity by a mean of 0.184 psu (positive: CTD saltier). This offset was also removed from the data below. The standard deviation of the adjusted TSG salinity from CTD values is 0.016 psu.
