Map of location of Sable Island

Sable Island is a sandbank formed by the meeting of currents from the St. Lawrence Delta and the Gulf Stream. It is located approximately 290km south-east of Halifax, Nova Scotia.

The observatory installation, funded as a joint venture between BGS, Sperry-Sun Drilling Services and Sable Offshore Energy, was completed in May 1999 and became operational from 8th May 1999.

In 2011, the ownership was transferred to BGS and operations have been maintained with the support of Environment Canada.

Sable Island magnetic observatory is part of the INTERMAGNET network.
