Real Time Data at L20-2 (1 km offshore in Mty Bay in 21 m water depth)

Click for a plot of the last week of nitrate, salinity, oxygen and chlorophyll

The mooring L20-2 has a surface measurement node (0.6 m depth) and a deep measurement node (16 m below the surface and 5 m above the bottom). Measurements at both nodes include:
  • Nitrate concentration (0.6 m and 16 m)
  • Salinity, Temperature and Depth (0.6 m and 16 m)
  • Oxygen concentration (0.6 m)
  • Turbidity (0.6 m and 16 m)
  • Chlorophyll biomass (0.6 m and 16 m)

The deep (16 m) node chlorophyll/turbidity sensor is not transmitting data in real time.

Go to Luke Coletti's webpage to reprocess UV spectra with different wavelength ranges or different models for the baseline.

The last UV absorption spectrum from the surface ISUS nitrate sensor at L20-2.
The spectrum has been processed to give the nitrate concentration.

Absorbance per cm

                          Wavelength (nm)                               

Black = Observed UV Spectra, Red = Modeled Baseline

(217 to 240 nm),  Green = Model Residuals (Abs. x 20)
