The ship’s crew and NOC researchers on board RRS James Cookwere joined by scientists from the British Antarctic Survey (BAS) this week as their quarantine ended ahead of the expedition to the massive A-68a iceberg in the South Atlantic.
A spectacular new species of Antarctic deep-sea crustacean armed with spines, large claws and the raptorial mouthparts of a predator, has been described by National Oceanography Centre (NOC) taxonomists.
Half of the drop in atmospheric carbon dioxide levels during glacial periods is the result of Antarctic sea ice modifying ocean circulation and acting as a ‘lid’, trapping carbon stored in the ocean beneath.
9 October 2015 – Nitrogen cycling in the oxygen minimum zone
Bess B Ward
Oxygen minimum zones form in a few special regions of the ocean due to the confluence of high productivity waters (usually fed by upwelling) and slow midwater ventilation. In these regions, depth intervals several hundred metres thick are completely devoid of oxygen.
A team of British scientists is making final preparations for an ambitious science mission that will use the National Oceanography Centre-provided Autosub underwater vehicle to monitor recent ice loss from the West Antarctic Ice Sheet.
Marine biologists have, for the first time, found a whale skeleton on the ocean floor near Antarctica, giving new insights into life in the sea depths. The discovery was made almost a mile below the surface in an undersea crater and includes the find of at least nine new species of deep-sea organisms thriving on the bones.
