The purpose of the Sustaining Arctic Observing Networks (SAON) is to support and strengthen the development of multinational engagement for sustained and coordinated pan-Arctic observing and data sharing systems. SAON was initiated by the Arctic Council and the International Arctic Science Committee, and was established by the 2011 Ministerial Meeting in Nuuk.
The SAON inventory builds on a survey circulated in the community at the inception of the activity. This database is continously updated and maintained, and contains projects, activities, networks and programmes related to environmental observation in the circum-polar Arctic.
Other catalogs through this service are AMAP, ENVINET and SEARCH, or refer to the full list of projects/activities.
To edit or add records to any of the catalogs, log in or create an account.
The GeoBasis programme collects data describing the physical and geomorphological environment in Zackenberg, North East Greenland. This includes meteorology, carbon flux and energy exchange, snow cover and permafrost, soil moisture, –chemistry and nutrient balance, hydrology, river discharge and – sediment
Aerosols, Clouds, and Trace gases Research InfraStructure - ACTRIS is a research infrastructure on the ESFRI roadmap from March 2016. ACTRIS is currently supported by the European Commission Horizon 2020 Research and Innovation Framework Programme (H2020-INFRAIA-2014-2015) from 1 May 2015 to 30 April 2019.
The objectives of ACTRIS Research Infrastructure
Detecting changes and trends in atmospheric composition and understanding their impact on the stratosphere and upper troposphere is necessary for establishing the scientific links and feedbacks between climate change and atmospheric composition.
Multidisciplinary investigations at the LTER (Long-Term Ecological Research) observatory HAUSGARTEN are carried out at a total of 21 permanent sampling sites in water depths ranging between 250 and 5,500 m. From the outset, repeated sampling in the water column and at the deep seafloor during regular expeditions in summer months was complemented by continuous year-round sampling and sensing using autonomous instruments in anchored devices (i.e., moorings and free-falling systems). The central HAUSGARTEN station at 2,500 m water depth in the eastern Fram Strait serves as an experimental area for unique biological in situ experiments at the seafloor, simulating various scenarios in changing environmental settings. Time-series studies at the HAUSGARTEN observatory, covering almost all compartments of the marine ecosystem, provide insights into processes and dynamics within an arctic marine ecosystem and act as a baseline for further investigations of ongoing changes in the Fram Strait. Long-term observations at HAUSGARTEN will significantly contribute to the global community’s efforts to understand variations in ecosystem structure and functioning on seasonal to decadal time-scales in an overall warming Arctic and will allow for improved future predictions under different climate scenarios.
