With the departure of the research vessel Polarstern from Punta Arenas (Chile) scheduled for this weekend, the "Summer Weddell Sea Outflow Study" (SWOS) international expedition will commence. Up to early April, a multidisciplinary international research team will investigate the northwestern region of the Weddell Sea—an area of central importance for the global climate and ocean system, but one that can only be explored on site by research icebreakers such as Polarstern due to challenging sea ice conditions.
