Polar field stations have been a key part of polar research for the past two centuries and one of the most tangible legacies of previous IPYs, yet they have been little studied. This novel project will look at field stations, both as sites of production of scientific knowledge in the field, and as flag carriers and symbols of geopolitical and diplomatic conflict and cooperation.

The Arctic coastal zone is sensitive to changes in marine, atmospheric, and terrestrial systems. Variations in sea ice extent, wave and storm intensity, air and water temperatures, and ground ice content affect the rate and magnitude of coastal change. A very sparsely populated region, the Arctic coastline is poorly observed when compared to temperate and tropical coastal zones, despite the fact that human systems in the Arctic are located in and dependent on processes in the coastal zone. The Arctic coastal zone needs to be monitored, both as a barometer for global change and for its human relevance. The international effort to align coastal observations in the Arctic is led by the Arctic Circumpolar Coastal Observatory Network (ACCO-Net). ACCO-Net includes a network of key sites setup by the Arctic Coastal Dynamics (ACD) project of the IASC, and 17 International Polar Year (IPY) projects from around the Arctic. ACCO-Net provides three categories of support to an SAON: 1) a network of regional experts responsible for running observations; 2) historical and current data in an Arctic circumpolar GIS database; and 3) a catalogue of site characteristics based on remotely sensed products. The regional experts have been assembled through IASC’s Arctic Coastal Dynamics project, and through the IPY project cluster on Arctic coastal observatories, which ACCO-Net leads. The coastal database is currently available in beta form, and includes a segmentation and classification of the circumpolar Arctic coastline. The current coastline used is the World Vector Shoreline, which has been divided into over 8000 segments on the basis of geomorphology, coastline position change rate, and ground composition, as well as other parameters. The GIS format allows searching and querying, and the database is currently mounted as an internet map server. The catalogue of site characteristics has two principle aspects: i) a monitoring template describing the primary and secondary monitoring parameters for each observatory site, and including links to standard operating procedures for each, and ii) standardized coastline position and digital elevation models for each observatory site, based on optical and infrared satellite data collected during IPY as part of the European Space Agency’s IPY program. ACCO-Net partner projects are currently selecting imagery for the catalogue and will co-ordinate their activities via a series of workshops supported by the International Space Science Institute.

The Network for ARCtic Climate and Biological DIVersity Studies (ARCDIV) is a multidisciplinary international research initiative. The project explores the diversity of ecosystem on Arctic archipelago Svalbard, central part of Isfjorden, Billefjorden and Petuniabukta, by integrating existing and new intensive measurements of key biological and physical variables and processes.

DAMOCLES (Developing Arctic Modeling and Observing Capabilities for Long-term Environmental Studies) is an integrated ice-atmosphere-ocean monitoring and forecasting system designed for observing, understanding and quantifying climate changes in the Arctic. DAMOCLES is specifically concerned with the potential for a significantly reduced sea ice cover, and the impacts this might have on the environment and on human activities, both regionally and globally.

We know that the Arctic exerts a critical influence on the Earth's climate and has done so for millions of years. Locked in Arctic ice and sediments are vital records of what the Earth's environment was like in the past. To more accurately predict the future of the Earth's climate, we need to know more about the extremes. Finding out how hot and how cold the Earth was in the past, and how much, as well as how little of it was covered by ice are key questions that APEX hopes to help answer.

The Circumpolar Flaw Lead (CFL) System Study is a major international effort under Canadian leadership that aims at understanding how changes in the physical system affect biological processes, towards a better understanding of the potential effects of climate change. The CFL project is part of the PAN-AME cluster.
