Hudson Bay Project, 1965: Aeromagnetic Surveys

Autonomous Aeromagnetic Surveys Using a Fluxgate Magnetometer

Recent advances in the research of autonomous vehicles have showed a vast range of applications, such as exploration, surveillance and environmental monitoring. Considering the mining industry, it is possible to use such vehicles in the prospection of minerals of commercial interest beneath the ground. However, tasks such as geophysical surveys are highly dependent on specific sensors, which mo...

The Paleomagnetic Significance of Aeromagnetic Surveys of the Hawaiian Islands!

Aeromagnetic surveys of the Hawaiian Islands have revealed that the pr imary magnetic anomalies associated with the islands are dipole anomalies caused by the intrusive rocks of the volcanic centers and rift zones. Comparisons of the direction of magn etization indicated by the dipole anomalies with results of laboratory measurements on iavas show that in many cases the lavas possess reverse po...

Teleconnection between the Arctic Oscillation and Hudson Bay river discharge

[1] Rising surface air temperatures in response to anthropogenic forcing are intensifying the global hydrologic cycle. Some of the more dramatic signs of climate change are increasing precipitation, evaporation, and freshwater discharge in continental river basins draining to high-latitude oceans. At regional scales, however, an acceleration of the hydrologic cycle is not always detected. In co...

Abundance indices of belugas in James Bay and eastern Hudson Bay in summer 2004 Indices d ' abondance

* This series documents the scientific basis for the evaluation of fisheries resources in Canada. As such, it addresses the issues of the day in the time frames required and the documents it contains are not intended as definitive statements on the subjects addressed but rather as progress reports on ongoing investigations. * La présente série documente les bases scientifiques des évaluations d...
