‘’So, for tomorrow, we have two presentations. Any other announcements?” In the library of the RV Sonne, Matt is wrapping up our daily meeting. As we wait for the Polarstern in Svalbard, we have time to exchange information about our respective atmospheric measurements for MOSAiC and learn to better know each other. It’s fascinating to listen about the different instruments and realize how complementary all our measurements are. The mast, the balloons, the remote sensing, the UAS… we have already discussed some analysis to link together and capture the plume above leads and identify different ways to measure turbulence and obtain fluxes. Matt also presented some preliminary results from leg 1. We were all thrilled to see the complementary data finally assembled to draw a bigger picture, linking the ocean, sea ice, and atmosphere. As we sat together in this warm library and looked at the slide from leg 1 results, I was reminded by the moment of waiting—waiting for the arrival of the Polarstern, waiting for going back to the ice—looking forward to adding more months to the time series presented on the slide. Therefore, we are here, in Svalbard, brimming with enthusiasm – something that the slow progression from the Polarstern won’t alter.
