Iqaluit and surroundings

Iqaluit centre (75 m resolution image)

This image is a section of a 300 m resolution overview, although its spatial resolution is original, that is 75 metres. In other words, the previous image was not a full resolution one. It shows the surroundings of Iqaluit on Baffin Island, Canada.

The settlement is characterised by several bright points representing larger buildings, or a small agglomeration of houses in the centre of the image. The landscape looks like a patchwork of different plates showing parallel stripes. They indicate the movements of the glaciers during the Ice Age, some 10 000 years ago. However, the rock is much older. It belongs to the Canadian Shield that built up more than 600 million years ago during the Pre-Cambrian period.

Frobisher Bay is filled with different types of ice. Some of the whiter areas that can be identified represent recently packed large floes. The black areas are so-called 'fast ice'. This fast ice has accumulated during the winter, and by the end of December it is already a few metres thick, and is not easy to penetrate with an icebreaker.

Find out the latitude and longitude of Iqaluit, and for how long the Sun appeared above the horizon on the day the satellite took this image (21 December 2003).

The satellite passed at 15.00 GMT. How high was the Sun above the horizon at that moment?
