Site description Sable Island is located in the Atlantic Ocean about 150 km off the eastern shore of Nova Scotia. The 41 km sandbar island is located on the continental shelf, and is based on a (former) moraine. It is partly eroded each winter, with the sand being re-deposited each summer. There is a constant shifting of the partially vegetated sand dunes and offshore bars - the patterns depending on direction and force of major storms. But on average, there has been little change over the last 200 years. The climate is maritime: windy and mild, with snow seldom lying on the ground for more than a few days. The tide range is about 2 m. About 16,000 Grey Seals pup on the island each January, with about 500 Harbour Seals pupping each June.
