Saving the Sea of Glass!
Glass sponge reefs are ancient, sensitive structures that are as fragile as glass due to an internal skeletal framework made of silica. Glass sponge reefs off Haida Gwaii, BC were first discovered in 1987; those in Howe Sound more recently. Sponges are evolutionarily ancient and the sponge reef formations are complex providing significant habitat for commercial, recreational and Indigenous food, social & ceremonial species of marine life that seek refuge and forage within the reefs. The long living reefs, however, are slow growing and vulnerable to physical damage that can impact long-term sustainability of their associated marine life. Reefs form at dark, cold depths on high current pinnacles, seamounts and submarine ridges but in Howe Sound, five of the reefs are SCUBA-diver accessible, providing unique research opportunities. A very exciting news announcement received on March 6, 2019 from the Honourable Member of Parliament, Jonathan Wilkinson, confirmed the need to protect these Howe Sound reef ecosystems as marine refuges. Come join us and become immersed in the biology and history of these incredible ‘cities of glass’ found virtually off our own back doorstep.
