PurposeResearch
ObjectivesRRS James Cook Cruise JC159 was a repeat occupation of the Atlantic hydrographic section at a nominal latitude of 24°S. As a repeat section it will enable the study of decadal variability, of the present circulation, and the present transports of heat, freshwater, and biogeochemical tracers. The previous occupation of this line was James Cook Cruise JC032 (2009). The cruise was a contribution to the project: Ocean Regulation of Climate by Heat and Carbon Sequestration and Transports (ORCHESTRA). The data collected during JC159 came from four main scientific teams, physics, chemistry (nutrients and oxygen), carbon, and CFCs. Four more sets of samples were gathered for analysis ashore: Stored water samples for isotopes of carbon (del13C and del14C) and oxygen (del18O). Also stored filters from filtering for Chlorophyll A and for microplastics
