| In this study we present hydrography, biogeochemistry and sediment trap observations between 2003 and 2012 at Porcupine Abyssal Plain (PAP) sustained observatory in the Northeast Atlantic. The time series is valuable as it allows for investigation of the link between surface productivity and deep ocean carbon flux. The region is a perennial sink for CO2, with an average uptake of around 1.5 mmolm(-2) day(-1). The average monthly draw-downs of inorganic carbon and nitrogen were used to quantify the net community production (NCP) and new production. Seasonal NCP and new production were found to be 4.57 +/- 0.85 molCm(-2) and 0.37 +/- 0.14 molNm(-2), respectively. The C: N ratio was high (12) compared to the Redfield ratio (6.6), and the production calculated... |
