To kick off data collection for NOAA Fisheries Pacific Islands, lead scientist Dr. Jamison Gove dives to the sinker of the Wave Glider’s Winch to take a water sample next to the Turner C3 fluorometer. Collecting chlorophyll-a, turbidity, and dissolved organic matter water samples at the beginning and end of the mission ensures that electronic measurements from the instrument can be validated. Chlorophyll-a is an important indicat
