Area of Expertise:
Chris Grandin is a biologist at the Pacific Biological Station. He currently holds the position of Hake stock assessment biologist. Prior to this position, he worked with the Inshore Rockfish section for 4 years. During that time, his focus was on video-based surveys and data. He 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. He has 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. He also had the amazing opportunity to become an ROV pilot and technician for the DFO-owned Phantom HD2+2. He has piloted for several rockfish surveys and analyzed the data afterwards, applying the same density estimation procedures he used for the Aquarius surveys.
