Ice Observations by the <i>Tiros II</i> Satellite and by Aircraft

Résumé

Discusses selected TIROS II photography in connection with simultaneous visual and photographic aerial coverage of Gulf of St. Lawrence ice conditions in Jan. and Mar. 1961. The narrow-angle camera and the 48 degrees inclination of the orbit tended to limit the reconnaissance to the southern fringe of winter sea-ice, though results suggest the feasibility of satellite photography for reconnaissance in the Arctic.
