Tier II monitoring provides real-time data from a dispersant-treated oil slick. When Tier II monitoring is used, a sampling team on a boat uses a fluorometer to continuously monitor for dispersed oil 1 meter under the slick. The team records fluorometer data and conveys them to the Unified Command. Water samples are also taken for later analysis at a laboratory.
