No longer polar opposites: the Arctic and the Antarctic are converging towards a seasonally dominated sea-ice regime

Over the satellite period, Arctic and Antarctic sea ice extent seemed to follow opposite pathways. Arctic sea ice showed a strong and prolonged decrease until 2007 and then stalled in its rate of decline. Antarctic sea ice extent, on the other hand, displayed a small but significant increase until 2015. After 2015, A...

Biological imprint dominates global mesoscale air-sea flux anomalies of carbon dioxide and oxygen

Systematic Ocean Ventilation Biases in Climate Models Indicated by Chlorofluorocarbon‐12

An accurate representation of ocean ventilation in models is crucial for simulating ocean uptake of heat and carbon, as well as the ocean's supply of oxygen. Using the Inverse Gaussian Transit Time Distribution technique, we assessed ocean ventilation in current climate models via comparing water ages —defined as t...
