The characterisation of processes in clouds, in the atmospheric boundary layer, surface layer and surface energy flux will lead to a better understanding of the lower troposphere, which interact with the surface in the Arctic. The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC, /ˌməʊˈzɛɪɪk/) expedition is a one-year-long expedition into the Central Arctic, planned to take place from 2019 to 2020. Die „Mosaic“-Expedition war die bisher teuerste und logistisch aufwendigste im Nordpolarmeer. „Wir haben die Grenzen des Machbaren verschoben, mehrere Rekorde gebrochen, die Landschaft neu definiert.“ Die Begeisterung ist Markus Rex anzuhören, als er von der Expedition berichtet. Which route Polarstern takes is determined by nature alone. The problem: Although icebreakers regularly break into the Arctic to collect measurement data. During MOSAiC, for the first time the Fram’s drift will be repeated with a research icebreaker, equipped with a veritable arsenal of cutting-edge instruments for exploring and recording the complex climate processes in the Central Arctic. An international group of educators, photographers, cinematographers, and scientists are teaming together to bring the MOSAiC expedition to everyone and anyone fascinated by the Arctic, including K-16 students across the globe. The emphasis will be on characterising snow cover and ice cover, and on arriving at a better understanding of the processes that determine their properties. On 20 September 2019 the ship will depart from the Norwegian port of Tromsø together with the Akademik Fedorov, proceed east along the Siberian coast, and at roughly 125° East, turn north and begin breaking into the sea ice of the Central Arctic, which will still be feasible at that time of year. MOSAiC's main goals are to investigate the complex and still only poorly understood climate processes at work in the Central Arctic, to improve the representation of these processes in global climate models, and to contribute to more reliable climate projections.[5]. [5][10], In addition, the outcomes of the MOSAiC mission will help to understand the regional and global effects of Arctic climate change and the loss of sea ice. Oktober 2020 "Polarstern" nach größter Arktisexpedition aller Zeiten in Bremerhaven. [3] In terms of the logistical challenges involved, the total number of participants, the number of participating countries, and the available budget, MOSAiC represents the largest Arctic expedition in history. Es gibt immer noch sehr, sehr viele Unwägbarkeiten. Die Auswertung wird Jahre dauern und die Wissenschaft dauerhaft verändern, so der Wissenschaftler. September 2019 in Tromsø. Dazu möchten wir Ihre Daten verwenden, um zum Beispiel genau auf Sie zugeschnittene Informationen liefern zu können oder ganz bestimmte Features, die Ihnen die Nutzung unseres Angebots erleichtern. In addition, helicopters will be employed. Bei Alarm ziehen sich alle auf das Schiff zurück und allzu neugierige Bären werden mit Schreckschusswaffen vertrieben. Diese Zustimmung wird von Ihnen für 24 Stunden erteilt. high-resolution models will be used for detailed studies, and these studies can provide the basis for improving regional and global climate models.[2]. Die driftende Eisoberfläche, auf der das Forschungscamp steht, ist äußerst dynamisch: Expeditionsleiter Rex: "Das Eis wird vom Wind über den Nordpolarbereich geschoben. Only by truly understanding what is happening in the Arctic will one be able to gauge how the climate will evolve in the future. During the set-up phase, RV Polarstern entered the Siberian sector of the Arctic in the thin sea ice conditions of late summer. Dabei besteht die Möglichkeit, dass Daten von Ihrem Computer zum jeweiligen Anbieter sowie Daten des Anbieters auf Ihren Computer übertragen werden. MOSAiC will contribute to a quantum leap in our understanding of the coupled Arctic climate system and its representation in global climate models. Es bilden sich Presseisrücken, es reißt immer mal wieder auf und darunter ist ein kalter, tödlicher Ozean.

MOSAiC is the first year-round expedition into the central Arctic exploring the Arctic climate system. Man kann beide verstehen. Alfred-Wegener-Institut / Esther Horvath (CC-BY 4.0), Rund 300 internationale Wissenschaftlerinnen und Wissenschaftler nehmen am MOSAiC-Projekt teil. The heart of MOSAiC will be Polarstern’s one-year-long drift through the Central Arctic. "MOSAiC" ist die größte Arktis-Expedition aller Zeiten. Sie sind erschöpft, aber überglücklich. [11] They will improve the preparedness of communities in the Arctic and northern mid-latitudes, provide the scientific basis for the development of policies for a sustainable development of the Arctic and support fact based decision-making in the areas of mitigation of and adaptation to global climate change.[7][10]. Oder gegebenenfalls repariert werden – und das praktisch ohne den im Labor gewohnten Nachschub an Ersatzteilen. Follow us live via the MOSAiC web app! Der Forschungseisbrecher Polarstern bricht 2019 in die Arktis auf. Ziel ist es, die Auswirkungen der globalen Erderwärmung zu erforschen. The distributed regional network further around the central observatory is comprised of autonomous and remotely-operated sensors, characterizing the heterogeneity of key processes in an area representing a typical grid box of modern climate models and providing invaluable data for the development of parametrizations for sub-grid-scale processes in climate models. The ship and the surrounding network are now drifting with the natural ice drift across the polar cap towards the Atlantic, while the sea ice thickens during winter (red dotted line in Figure 1).
