This expedition will build on existing work done by Glen Dennison on the glass sponge reefs. Glen is an ocean explorer and citizen scientist and he has personally discovered ten of the known sponge reefs in Howe Sound. He has done this through both air-gas diving, and the use of a low-cost drop-camera system. Over the years, Glen has mapped many sites in Howe Sound and has collected hours of drop-camera footage on the sponge reefs. The bathymetric data, in combination with the drop-camera footage can be used to visualize the boundaries of the glass sponge reefs; as well as map relative sponge coverage throughout the reef.
Recently, a group of students at Fleming College worked in collaboration with Glen to create a bathymetric map and relative density surface of the East Anvil Island glass sponge reef. This was done by extracting still images from drop-camera video data and classifying the geo-referenced images.
The goal of this project is to build upon existing work and contribute to existing datasets. We will produce higher resolution maps of the glass sponge reefs using the ROV in combination with the plethora of data already collected by Glen.
