[{"name":"oden-ao-2018-expedition-3","title":"Data from expedition Arctic Ocean, 2018","summary":"The Arctic Ocean 2018 expedition was carried out during summer 2018 in the central Arctic Ocean.\r\n\r\nWith the Swedish icebreaker Oden serving as the research platform, a range of scientific investigations were made, including the microbiological life in the ocean and ice and how it's connected to cloud formation in the Arctic. Oden was mainly drifting with the pack ice to collect undesturbed air measurements. Data provided in the database here comprise weather station data, aerosol physical and chemical properties, atmospheric gas data, cloud and fog properties, micrometeorology, boundary meteorology, air trajectories, ocean biology and chemistry data and high-resolution bathymetry.\r\n\r\nThe expedition is also referred to as MOCCHA-ACAS-ICE. The expedition started and ended in Troms\u00f8, Norway, and lasted from July 31 to September 25, 2018.","citations":"Leck C, Matrai P, Perttu A-M, G\u00e5rdfeldt K (2019) Expedition report: SWEDARTIC Arctic Ocean 2018, Swedish Polar Research Secretariat, 90 pp,  ISBN 978-91-519-3671-0\r\n\r\nBaccarini A, Karlsson L, Dommen J, Duplessis P, V\u00fcllers J, Brooks IM, Saiz-Lopez A, Salter M, Tjernstr\u00f6m M, Baltensperger U, Zieger P, Schmale J (2020) Frequent new particle formation over the high Arctic pack ice by enhanced iodine emissions.

The frame setting goal of AO2018 was to increase our knowledge of low- altitude clouds over the central Arctic Ocean by studying processes that are important to their formation and occurrence. This was achieved through highly interdisciplinary studies in which cloud formation was linked to the microbiological life in the ocean and ice, by means of detailed observations made from several hundred metres below the ocean\u2019s surface to many kilometres up in the atmosphere:\r\n\r\n* physical, chemical and biological characterization of the ocean and ice\r\n* measuring exchange processes at the ocean-air interface\r\n* sampling gases and aerosol particles and cloud\/fog in the atmosphere\r\n* measuring meteorological processes in the lowest layer of the atmosphere\r\n\r\nAO2018 was the fifth research expedition to the central Arctic Ocean to support research on processes that are important for the formation and life cycle of low-altitude clouds over the pack ice: the earlier expeditions took place in 1991, 1996, 2001 and 2008. Access to the icebreaker \u200bOden as a research platform, combined with the logistics support provided by the Swedish Polar Research Secretariat and Oden\u2019s crew, offered the researchers a unique opportunity to conduct advanced and innovative research in a highly inaccessible region with limited influences by human activities.\r\n\r\nThe expedition was made in collaboration between Sweden and the US National Science Foundation (NSF).\r\n\r\n##### How to cite\r\nPlease, cite each individual dataset whenever they are used or cite this collection when that is more
