Level 1: General International

• Global Earth Observation System of Systems(GEOSS)
  The Group on Earth Observations (GEO) is an intergovernmental organization working to improve the availability, access to and use of Earth observations by building a Global Earth Observation System of Systems (GEOSS), which provides decision-support tools to a wide variety of users. As with the Internet, GEOSS will be a global and flexible network of content providers allowing decision makers to access an extraordinary range of information at their desk. The GEOSS Portal is the main entry point to Earth Observation data from all over the world. The GEOSS information services for cold regions, which may service as the GEOSS Community Portal functions, coordinates joint, global efforts to provide Earth observations and information services to decision-makers over a vast Cold Regions area, including the North Pole, South Pole, Himalaya-Third Pole and Mountain cold regions.

• Polar Data Catalogue
  The Polar Data Catalogue is a database of metadata and data that describes, indexes, and provides access to diverse data sets generated by Arctic and Antarctic researchers. Geographic focus is on Canada, but the PDC holds international collections, too, such as hundreds of metadata records of the Circumpolar Biodiversity Monitoring Program. The records follow ISO 19115 and Federal Geographic Data Committee (FGDC) standard formats to provide exchange with other data centres. Interoperability via OGC WMS, OGC WFS, OAI-PMH, and CSW (GeoNetwork) are in place for sharing metadata and data. The metadata records cover a wide range of disciplines from natural sciences and policy, to health and social sciences. Datasets are available for free public download, with new files being added on a regular basis as we work with researchers to prepare and submit their datasets. The PDC Geospatial Search tool is also available to the public and researchers alike and allows searching data using a mapping interface and other parameters.

Level 3: National Polar

• Polar Knowledege Canada
  Polar Knowledge Canada (POLAR) is on the cutting edge of Arctic issues and strengthens Canada's position internationally as a leader in polar science and technology. POLAR also promotes the development and distribution of knowledge of other circumpolar regions, including Antarctica. It will provide a world-class hub for science and technology research in Cambridge Bay, Nunavut called the Canadian High Arctic Research Station. As part of Canada's Northern Strategy, POLAR improves economic opportunities, environmental stewardship and quality of life for Northerners and other Canadians.

• Sea Ice Prediction Network (SIPN)
  Decline in the extent and thickness of Arctic sea ice is an active area of scientific effort and one with significant implications for ecosystems and communities in the Arctic and globally. Forecasting for seasonal timescales (i.e., the summer and into fall) is of particular interest to many stakeholders since many activities that take place in the arctic are planned over the summer months, and many species are sensitive to the behavior of summer sea ice. However, seasonal forecasting is particularly challenging due to the variable nature of weather and ocean behavior over that timescale as well as current limits to data and modeling capabilities.

  Building on the ongoing success of ice drifters that support multiple discrete subsurface sensors on tethers and the WHOI-developed Moored Profiler instrument capable of moving along a tether to sample at better than 1-m vertical resolution, we designed and field tested an automated, easily-deployed Ice-Tethered Profiler (ITP) for Arctic study. The system consists of a small surface capsule housing a controller interfaced to an Iridium data telemetry unit and inductive modem, a plastic-jacketed wire rope tether extending down 500 to 800 m into the ocean terminated by a ballast weight, and a new variation of the WHOI Moored Profiler (in shape and size much like an Argo float) that mounts on the tether and cycles vertically along it.
