Revelle: More Moorings, Sun and Some Fish

We took advantage of a sunny, temperate weather window on Sunday to deploy moorings T1 and T3. We loaded each of the moorings with 36 temperature sensors, which spanned half a kilometer of line, and three CTD’s, instruments that use a band of sensors to measure the water’s conductivity, temperature and density. For each of the moorings we’ve deployed so … Read More
