Mark grew up sailing out of Victoria British Columbia, where he always took any opportunity to get on the water. Today, Mark is the senior zodiac skipper and wildlife guide at Prince of Whales Whale Watching in Victoria, where he shares his passion for the ocean with people from all over the world. Since 1997, Mark has been involved in photographing whales year round to help researchers better understand whale movement in southern B.C. waters. He is a lead contributor to a photo identification catalogue of Bigg’s transient killer whales of B.C. and S.E. Alaska published by the Cetacean Research Program. He is also documenting humpback whales in the waters off Southern Vancouver Island and adjacent Washington State. Mark has produced a humpback whale catalogue in collaboration with the Centre for Whale Research (San Juan Island, WA) and the Cetacean Research Program (Fisheries and Oceans Canada), which compiles and maintains the B.C. wide Humpback Whale Catalogue.  He contracts for Fisheries and Oceans Canada as a research assistant and marine mammal observer during cetacean surveys throughout the waters of British Columbia and volunteers with the Center for Whale Research.
