mission of Canada’s RADARSAT-1 which has collected a

unique archive of imagery over this area for future

studies focused on changes over time. Until recently, the

efforts deployed for the International Polar Year focused

solely on observations during this time period to support

science. Canada’s Arctic monitoring program will ensure

a legacy from the Polar Year observations by rooting

them in on-going monitoring and providing a mecha-

nism for information to be transmitted to decision

makers.

Comprehensive EO to support northern development

The major federal government departments active in

Canada’s north are currently developing a federal Earth

observation strategy that will include a major northern

component. This observation plan will provide for

sustained in-situ and remote observations of the Arctic,

coordinated with international partners. It will also

generate information products used to support decision

making, whether in relation to resource development,

infrastructure construction, pollution monitoring or

other areas of decision support.

Canada’s north is undergoing rapid change, and

Canada’s decision makers need new tools to track and

understand this change. As wildlife such as Canada’s

polar bears struggle to adapt, mitigation strategies

depend on comprehensive information and under-

standing. The unique but fragile environment of the

north offers exceptional development opportunities but

these must be pursued in a context of heightened stew-

ardship and environmental awareness to ensure Canada’s

Arctic remains a beautiful and pristine legacy for future

generations of Canadians.

development of the north, as well as cruise ships, the development

of local fisheries, and transit cargo.

While eventually the Northwest Passage could offer a significantly

shorter maritime route from Asia to eastern North America and

Western Europe, it is unlikely to become a major shipping lane until

environmental conditions are better understood and logistical issues

are dealt with. Nevertheless, destination shipping seasons in the

north are lengthening, bringing increasing traffic to the Port of

Churchill and other locations. Important new port infrastructure is

being built. Canada intends to ensure that maritime traffic in the

north is safe and respects Canadian environmental legislation; satel-

lite sensing is a key component of this strategy.

Building on existing observations

Canada already maintains a vast network of environmental moni-

toring stations across the Canadian north. In the future, more stations

are expected to add to Canada’s observations to support compre-

hensive weather and climate monitoring. The integration of this

information with satellite-based observations is critical. Satellites

already provide ad hoc coverage of the north to support specific operations.

During the International Polar Year, unprecedented volumes of

satellite data will be collected to support scientific research over the

Canadian Arctic. These data complement the 12-year background
