GLASS SPONGE RESEARCH

​

My M.Sc. research examined the ecology of glass sponge reef habitat off the coast of British Columbia, Canada. Glass sponge reefs are unique to Canada's Pacific coast. These reefs function in deep-sea nutrient recycling and form complex habitat structures on the seafloor that increase deep-sea biodiversity. Evidence of trawl damage has been observed in the reefs. To mitigate these threats, Canada declared the Hecate Strait and Queen Charlotte Sound reefs a marine protected area (MPA) in February 2017. I used multi-scale mapping to study the distribution of live and dead sponge cover in the reefs. I also inventoried reef-associated fauna and helped describe a new sponge species in the genus Desmacella. My findings informed policy-makers about the health conditions of the reefs to improve long-term MPA monitoring and conservation strategies.
