Hydrographic profiles using conductivity, temperature and depth (CTD) sondes were obtained across straits and along channels to best cover water column structure around the island. Two separate, but identical pumped Seabird 19plus CTDs with Biospherical scalar photosynthetically active radiation (PAR) and Seabird ECOtriplet fluorometer sensors, were used to collect hydrographic profiles, one standalone (autonomous) CTD and one mounted on the ship’s rosette. It is noted that the ship’s rosette also had a Seabird dissolved oxygen sensor. There were more than 200 profiles collected in total with very good coverage around the island. Rosette data was collected using a Seabird 32 pylon, 19Plus V2, and 33 deck unit. Rosettes are water sampling instruments used in conjunction with oceanographic sensors to measure a number of variables. Rosettes give us a detailed snapshot of the entire water column through these sensors and through water samples collected at various depths within the column.
