The [[Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area]] was designated by the [[Fisheries and Oceans Canada]] in February 2017. The MPA is located in the Northern Shelf bioregion of the Pacific Region, southeast of [[Haida Gwaii]], North and South of the entrance to the Douglas Channel. The MPA is composed of three individual areas known as the Northern Reef, the Central Reefs, and the Southern Reef. Together these three areas cover approximately 2,410 square kilometers.<ref>{{Cite web|url=http://www.dfo-mpo.gc.ca/oceans/mpa-zpm/hecate-eng.html|title=Fisheries and Oceans Canada|website=www.dfo-mpo.gc.ca|language=en|access-date=2018-11-22}}</ref> The four reef complexes in the Hecate Strait and Queen Charlotte Sound discontinuously cover an area of about 1,000&nbsp;km<sup>2</sup>, and are located in glacial troughs between 140 m and 240 m deep.
