Current research and/or projects

I have recently acquired the position of Hake stock assessment biologist. Prior to this position, I worked with the Inshore Rockfish section for 4 years. During that time, my focus was on video-based surveys and data. I had the enjoyable experience of submerging down to 300 meters into beautiful rockfish habitat on Nuytco’s Aquarius submersible and recording line-transect observations of rockfish with which density estimates could be calculated using program DISTANCE. I have applied such density estimates to habitat areas which were extracted from bathymetric multibeam maps using raster derivatives and nearest neighbour techniques developed by our team. I also had the amazing opportunity to become an ROV pilot and technician for the DFO-owned Phantom HD2+2. I have piloted for several rockfish surveys and analyzed the data afterwards, applying the same density estimation procedures I used for the Aquarius surveys.
