This map shows the depth of the deepest dissolved nitrate (NO3-) measurement made at each DSDP/ODP Site. If a site is not plotted, there are no NO3- measurements in the database. The map does not contain any information regarding the number or density of measurements, or the data quality.

Meters below sea floor (mbsf) to which NO3- concentration data extend at each site.
