| Definition | An in situ UV absorption spectrophotometer that measures nitrate concentrations in the ocean. The sensor is rated to either 500 m or 6000 m. It uses a Xenon flash lamp as a light source and has a path length of either 70 mm or 200 mm, permitting nitrate detection up to 400 uM or 100 uM, respectively. The minimum nitrate detection limit is 0.2 uM and accuracy is +/- 0.2 uM. Nitrate concentrations are determined from the ratio of the absorption at 220 nm and 280 nm. The sensor was developed by NOC in association with Valeport Ltd. | |
