Any data from ship-mounted instruments as well as analyzed water samples collected during deployment/recovery expeditions. 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. Underway data and documentation from UNOLS vessels used during maintenance cruises can be found at the Rolling Deck to Repository (R2R) site, while documentation from each cruise, including the cruise plans, manifests, equipment lists, description of events, and full cruise reports can be found in the OOI document management system.
