Nitrate Plot

Nitrate is the form of nitrogen used by phytoplankton (small plants in the
ocean) for new production and growth. An In Situ Ultraviolet Spectrometer
(ISUS) attached to the SeaSoar absorbs UV radiation in the water to calculate
the nitrate concentrations in the water column. These nitrate measurements
provide information on spatial availability for phytoplankton production and
potential pathways of nutrient supply for the shelf.
