This report describes the new regional integrated physical and ecosystem flux array deployed in the important eastern boundary of the subpolar North Atlantic. This array is novel and provides the first intra-annual measurements of pH, dissolved inorganic nutrients and dissolved oxygen in the region. Additionally, temporally varying transports of ecosystem-relevant parameters have been calculated for the first time. The report establishes the methodology used to calibrate biochemical sensors, derive nutrient and carbon time series, and calculate physical and ecosystem-relevant fluxes. It also details 8 main findings
