Ocean gliders were first acquired by Fisheries and Oceans Canada in year 2017 and 2018 for both the West and East coasts. On the East coast, they have been used to monitor hydrographic sections associated with the AZMP. Here, the AZMP Halifax line is occupied from outside the mouth of Halifax harbor, Nova Scotia Canada at (44.267N, 63.317W) in the off-shelf direction approximately 135 nautical miles to deep waters off the continental slope at (42.475N, 61.433W)."
