| Abstract | due to the spatiotemporal sampling limitations. To better understand the role of DOC in the Southern Ocean biogeochemical cycles, the Brazilian High Latitude Oceanography Group (GOAL) has carried out a continuous effort of DOC summertime observations, in the northern Antarctic Peninsula (NAP) since 2015. Here, we present an overview of recent advances in the study of DOC distributions along the NAP, between 2015 and 2019. We collected 894 DOC samples across 205 oceanographic stations. Samples were measured as non-purgeable organic carbon. DOC excess (ΔDOC) was calculated by subtracting surface and deep DOC concentrations. DOC concentrations in the NAP ranged from 33.0 to 162.0 µmol kg1 , with a median of 49.2 µmol kg1 . Surface DOC accumulation and vertical export occurred especially in the Gerlache Strait, the Bellingshausen Sea and, near the land portions of the Bransfield Strait, producing a maximum ΔDOC of 20 µmol kg1 , compared to the DOC available in NAP deep waters (~44 µmol kg1). Minimum DOC concentrations (< 45 µmol kg1) could be observed at the surface in the eastern basin of the Bransfield Strait, with concentrations increasing towards the Weddell Sea. The wide DOC spatial coverage and the continuity of annual summer sampling have made it possible to identify both significant differences in DOC distributions among the different NAP regions, interannual differences considering the data collected in the same regions. Furthermore, El Niño - Southern Oscillation and Southern Annular Mode impacted DOC distribution in Bransfield Strait between 2015 and 2016. Thus, DOC can be considered an important proxy to evaluate the coupling between physical, biogeochemical and climate processes over time. | |||
