The Arctic Research Icebreaker Consortium (ARICE, www.arice-h2020.eu) and Association of Polar Early Career Scientists (APECS, www.apecs.is) invited for a webinar on “Arctic Ocean Ventilation – Why it matters and how to measure it” on 11 October 2021 from 12:00 – 13:00 pm GMT
The Arctic Ocean is a critical part of the global ocean and the global climate system, and we know climate change is happening faster there than anywhere else on the planet. With this in mind, the VACAO (Ventilation and Anthropogenic Carbon in the Arctic Ocean) project, funded by ARICE, set out to better quantify Arctic Ocean ventilation. With ventilation we mean the process that brings water from the surface ocean to the deep ocean, and back again. This process bring characteristics of the atmosphere to the interior ocean, such as extra heat and carbon dioxide, and eventually distribute this to the global ocean. We report on preliminary results from a very recent cruise on the IB Oden where we measured and took samples for a large range of ocean ventilation tracers.
