Comment:
Nutrients were analyzed in an air-conditioned lab container with a Technicon TRAACS 800, continuous flow auto analyzer. Measurements were made simultaneously on four channels: phosphate, silicate, nitrate and nitrite together, and nitrite separately. All measurements were calibrated with standards diluted in low nutrient seawater.
