Summary: Just as high and low pressure systems drive normal weather, high and low voltages drive space weather. The radar network is designed to measure these voltage patterns several hundred kilometers above the ground, and these patterns project out into space along the Earth's magnetic field lines. The radar installation is rather simple, requiring transmitting and receiving electronics in a small bu...

Summary: This project seeks to carry out the first detailed study of the newly discovered Tunnunik impact structure, located on Victoria Island, NWT. The research team will carry out field mapping and conduct gravity, ground magnetic, and seismic surveys, and sample for paleomagnetic studies. They will also ground-truth a remote predictive map generated with Radarsat-2 and other satellite data. The goal...

Summary: Just as high and low pressure systems drive normal weather, high and low voltages drive space weather. The radar network is designed to measure these voltage patterns several hundred kilometers above the ground and these patterns project out into space along the Earth's magnetic field lines. This information is critical to personnel in space and to maintenance of the satellite telecommunications. ...

Summary: The objective of the airborne survey is to acquire high-resolution airborne gravity gradient and magnetic data. Airborne gravity gradiometry surveys measure small variations in the rate of change of the gravity field due to lateral variations in the mass and density of underlying bedrock. Aeromagnetic surveys measure magnetic properties of bedrock and are one of the tools used in geological mapp...

Summary: This survey will improve public knowledge and understanding of the geology of this area, as no publicly available magnetic coverage exists. Survey lines will be flown at a spacing of 880 metres and a 330 metre mean terrain clearance. The purpose of the s...

Summary: In previous years, instruments were installed in Clyde River, Igloolik, Pelly Bay, Gjoa Haven, Pangnirtung, Coral Harbour, Repulse Bay, Cape Dorset and Iqaluit in order to measure the earth's magnetic field. Data will be collected continuously by these instruments, called magnetometers, for a period of several years. This information will help us to understand the nature of the aurora borealis....

Principal Investigator: Newitt, Lawrence R.
Licenced Year(s): 1994
Summary: The researchers will take measurements of the magnetic field at 10 sites using a magnetometer-theodolite. For each site, the strength and direction of the magnetic field will be measured. This information will be used to re-determine the position of the north magnetic dip pole. This information is important for producing magnetic charts for Canada and providing information to the Geological Atl...

Summary: The Sapphire North Radar System uses 2 transmitters, at Sachs Harbour and Rankin Inlet, and a common receiver at Yellowknife. This system measures speeds of structures in the ionosphere (upper atmosphere) in order to study the transfer of energy from the solar wind to the earth. This energy transfer is most apparent during "magnetic storms" when there are displays of northern lights. The researc...

Principal Investigator: MacLean, Brian
Licenced Year(s): 1993 1990
Summary: This survey will take place from a ship travelling through the Hudson Strait and Ungava Bay region. The researchers will collect information on the history and characteristics of the seabed. Some samples of sediments on the seafloor will be taken for further analyses. Transfer of a few of the ship's crew may take place at Cape Dorset but all other activities will take place in locations remote ...

Summary: For much of the Earth's history, the arctic has had a mild climate, quite unlike the conditions that now exist. Evidence that supports this past climate are fossil plants and animals (including crocodiles and tortoises) found in the arctic. The Earth's magnetic field has changed over time and these changes are contained in the fossils. This research will try develop a technique to age these fos...
