There will be a Challenger 150 webinar during the first day of the Deep Central Arctic Ocean (DASCAO) workshop! Join experts Eva Ramirez-Llodra, Ana Hilário, and Stefan Bünz for a day of talks and discussion where natural scientists and governance experts are brought together to assess the latest knowledge on the composition, structure and processes of deep Arctic ecosystems. The goal of this event is to support the conservation and management of the Central Arctic Ocean.
