“Dense water out of the Antarctic shelves is expected to drive the transport of carbon into the deep Southern Ocean via the formation of Antarctic Bottom Water. However, bottom water formation’s capacity to sequester carbon into the deep ocean is poorly constrained. Here, dissolved organic carbon (DOC), dissolved black carbon and particulate organic carbon were examined to reveal the influence of the Weddell Sea Deep Water on DOC transport. … This study highlights the key role of the Antarctic continental shelf pump in carbon sequestration.”
