The present publication recording research in progress La présente publication, qui fait état de la recherche in Canada from May 1982 to April 1983 is the result of a réalisée au Canada de mai 1982 à avril 1983, est le fruit d'une survey conducted between January, 1983 and March, 1983. enquête effectuée entre Janvier 1983 et mars 1983.

The research projects listed in this compilation are Les projets de recherche enuméres sont exécutés being undertaken mainly within federal and provincial depart­ surtout par des ministères fédéraux et provinciaux, et par des ments, and universities. Data on industrial research was not universités. Les données sur la recherche industrielle n'ont received. A relatively complete overview of scientific pas été reçues. Un aperçu assez complet de l'activité de research activities within Canada in the geological and allied recherche scientifique au Canada pour la periode visée dans sciences, however, is provided for the survey period. le domaine de la géologie et des sciences connexes est cependant fourni.

Au moins 464 At least 464 research projects have not been previously projets nous ont été signalés pour la première fois. Les reported. The greatest increase during the 1982-83 period domaines où la recherche s'est le plus accrue durant l'année was in the fields of Mineral/Energy Geoscience (70), 1982-1983 sont les sciences de la Terre- Geophysics (44) and Geochemistry (41). Research projects Énergie/Minéraux (70), la géophysique ~44), et la undertaken as graduate thesis in the universities are so géochime (41).
