During each maintenance cruise, CTD casts are performed prior to deployment and following recovery of most OOI assets (glider deployments may involve a single reference CTD cast). Water samples are collected in Niskin bottles at multiple depths, and analyzed for oxygen (Winkler), chlorophyll-a fluorescence & pigment distribution, nitrate/nitrite (and potentially a full nutrient suite), total DIC & total alkalinity, pH, and salinity.
