This data package contains water chemistry measurements taken approximately bi-monthly at 3 stations on the north shore of Moorea, French Polynesia: Forereef, Lagoon, Fringing Reef. Nutrients are measured from water samples collected with Niskin bottles or Falcon tubes. For completeness, nutrient measurements are reported even when concentrations are below the detection limit of the method, which commonly occurs at this site. Sampling began in August, 2005 and is ongoing.
