Description

Isotope Analysis conducted using the Denitrifier Method on all samples received with nitrate concentrations greater than 0.30 uM nitrate.  Nitrite removal performed where noted in the comments section.

Results are published in Marconi et al (2015).

DMO Note: Fully unrestricted data, including the dNO3 columns served on 2018-12-26. Previous version of revised data was served on 12 March 2014.  Original data were served in March 2013.

Please note that data may not be final, pending intercalibration results and further analysis. If you are interested in following changes to US GEOTRACES data, there is an RSS feed available from the GEOTRACES-NAT project page.
