PurposeResearch
ObjectivesThe RRS James Cook 090 cruise was the concluding phase of the fieldwork for the Ocean Surface Mixing, Ocean Sub-mesoscale Interaction Study (OSMOSIS) consortium and sought to recover 9 moorings and 2 gliders, to conduct hydrographic and biogeochemical measurements for mooring and glider calibration, and to obtain opportunistic measurements of upper-ocean microstructure and air-sea CO2 fluxes.

Operations were very successful. All moorings and gliders were safely recovered, with near-complete data return. Three out of the four guard buoys that had been deployed around the inner mooring cluster were also recovered, with the fourth guard buoy (which had sunk upon deployment) failing to rise to the surface after release. Nearly 700 upper-ocean microstructure profiles were obtained in several transects within the mooring area. 9 CTDs were conducted, and underway measurements of biogeochemical parameters and air-sea CO2 fluxes obtained throughout much of the cruise. The meteorological buoy at the Porcupine Abyssal Plain (PAP) observatory was also serviced successfully.
