Sampling

Triplicata sampling of 125ml of water on:

    • the outer slope (at -20m)
    • the barrier reef (at -0.5m)
    • the fringing reef (at (-0.5m)

Analysed nutrients

  • Phosphate PO4 (µM)
  • Nitrates NO3 (µM)
  • Nitrites NO2 (µM)
  • Silice Si(OH)4 (µM)
  • Ammonium NH4+ (µM)
Note: -99 in stored data means no data and -98 in Ammonium means < 0,05µM

Analysis method

The analysis are realised at CRIOBE using the Autoanalyser AA3 (SEAL Analytical), by methods described by Aminot & Kérouel, 2007. Before 2013, the analysis were done by CAIRAP.
