I. Aerospace (A. Jablonski)

Aerospace category covers all disciplines associated with aerospace activities in Canada and they include, but are not limited to, the following areas on the space side: space sciences, space technologies and earth observation from space. Several government departments are involved with the leading role being the Canadian Space Agency in all space-related activities ( and the Institute for Aerospace Research, National Research Council of Canada in all R&D aeronautical activities ( The present list represents selected existing databases in this category only.

Space Sciences
Canadian Space Agency (CSA) provides the framework for the peaceful use and development of space to meet Canada’s social and economic needs, and to develop an internationally competitive space industry. Space sciences activities are supported in 6 areas: space astronomy, space environment, atmospheric environment, space life sciences, microgravity sciences and planetary exploration. National Research Council Canada (NRC) is the national adhering member of the International Committee on Space Research (COSPAR). However, in 1993, NRC and the CSA agreed that the CSA would be responsible for the Canadian Committee (CNC) for COSPAR. Since then, COSPAR obligations have been shared between the two agencies. The National Research Council’s Advisory Committee on International Science, Engineering and Technology (CISET) advises both NRC and CSA on COSPAR issues. Communication between the CNC/COSPAR , and NRC is managed by the NRC’s International Relations Office. The CNC is made up of the existing advisory committees to the Space Science Program of the CSA. Dr. David J. W. Kendall of the CSA is the Canadian Representative to COSPAR Council. The following advisory committees comprise the CNC/COSPAR:
Space and Atmospheric Environment Advisory Committee (SAEAC)
The Joint Committee on Space Astronomy (JCSA)
Life Sciences Advisory Committee (LSAC)
Microgravity Sciences Advisory Committee (MSAC)
Canadian Advisory Committee on Scientific Utilization of Space Station (CACSUSS)
Their membership lists are available at the CSA web site .

Hazards and Environmental Geosciences
A number of databases compiled by scientists of the Terrain Sciences Division of the Geological Survey of Canada, Natural Resources Canada are now accessible through the Internet. These databases provide key geoscience data that are useful for hazard assessment, environmental impact assessment, land use planning and climate change studies. Included in the collection are the national permafrost database, the Canadian peatland database, the Canadian diatom database, landslide disasters, flood disasters, borehole geophysical logs, the radiocarbon database and eolian sediment transport data. Databases are accessed through interactive maps.

Cryospheric Databases
The Global Terrestrial Network for Permafrost (GTN-P) was established in 1999 by the International Permafrost Association under the Global Climate Observing System of the World Meteorological Organization. The GTN-P is an international network of permafrost observatories designed to provide long-term field observations of active layer and permafrost thermal state. These observations are essential for the evaluation of current permafrost conditions, detection of the terrestrial climate signal in permafrost and its spatial and temporal variability and for the development and validation of climate change models. The Geological Survey of Canada hosts the GTN-P web site and the data management node for the thermal monitoring component.

The Geological Survey of Canada maintains national permafrost thickness and temperature databases. Permafrost temperature data are available on-line and work is currently underway to make other permafrost related data sets more accessible. These databases provide baseline information that are useful for climate change studies, for planning northern development and for environmental impact assessment.

CRYSYS (Cryospheric System in Canada) is a specialized research group studying the Canadian cryosphere, which includes snow, glaciers, permafrost and lake and sea ice. Information on the state of the Canadian cryosphere is required for supporting the climate change research community, for development and validation of climate and hydrological models and for the making of operational and policy decisions by government. Maps and imagery showing snow cover distribution, sea ice extent and other aspects of the cryosphere may be accessed through the State of the Canadian Cryosphere section of the CRYSYS web site. The Canadian Cryospheric Information Network (CCIN) is currently under development and will act as a central archive and distribution node for Canadian cryospheric data.

VI. Geospatial (J.P. Lauzon)

Data initiatives in Canada are progressing along the path established over the past several years. The federal government has initiated a number of programs to enhance the quality and accuracy of geographic information being captured. Using Global Positioning System (GPS) technology, the digital representation of the major Canadian road network is being updated. Supplemented by similar efforts among provincial and municipal governments as well as private industry, the enhanced representation of the road network is supporting the adjustment of other geographic entities, particularly administrative boundaries that use the network in their definitions.

There have been efforts at all levels of government and in the private industry to document datasets through standard metadata templates. These templates significantly enhance the ability to find data through data discovery portals. One example is the increased number of datasets that can be discovered and downloaded through the GeoGratis program

Canadian geospatial data standards and approaches to the discovery and manipulation of data using distributed on-line services are synchronized with the ISO TC211 and Open GIS Consortium (OGS) standards (OGIS). The Canadian government and many Canadian private companies now actively participate in these international and industry standards organizations ensuring Canadian contribution and compliance to these evolving standards.

VII. Physics - Astrophysics (H. Dabkowska)

The Canadian Astronomy Data Center (CADC) continues to be the role model in data activities in astronomy. It was established in 1984, and successfully handles the data produced by Canadian astronomers, facilitating the exchange of raw and re-calibrated data. For more information about current activities, please visit their web site at

For data from the Hubble Space Telescope (HST) an innovative way of presenting raw and calibrated files was developed and is widely used.

F*A*C*T is available for use with Windows.

B. University Research Programs
Profs. C. B. Alcock and V. Itkin (University of Toronto) assess thermodynamic data of the elements (Debye temperature, Cp(T), enthalpy, third law entropy and fusion properties). Cp data are described by several equations and recommended data are given.

Prof. A. E. Mather (University of Alberta) measures vapour?liquid equilibria and enthalpies of reaction and solution for acid gases in aqueous solution of polar organic solvents (application in gas purification). He has contributed to the IUPAC Solubility Data Series in compilation and assessment of data for CO2 in water and non?aqueous systems, as well as for solids and liquids in supercritical CO2.

Prof. P. Englezos (University of British Columbia) measures gas hydrate phase equilibria involving methane, CO2, hydrocarbons and nitrogen. Measurements also include the solubility of calcium carbonate in the presence of adsorbed substances.

Prof. P. R. Tremaine (Memorial University, Newfoundland) measures thermodynamic and spectroscopic properties of aqueous ions, complexes and non-electrolytes over an extended range of conditions up to and including the near-critical regime. These properties are sensitive to solvation effects and are being used at Memorial and elsewhere to develop semi-theoretical "equations of state" for modelling the behaviour of aqueous solutes in systems of geochemical and industrial interest.
