Deep in the ocean off Vancouver Island’s west coast, a gas associated with climate warming is making its way to the surface. Nitrous oxide is a product of plankton decomposition, pulled to the surface in areas where deep-sea waters migrate upwards in what’s known as coastal upwelling. Where is it coming from? That’s a question that University of Victoria PhD student Brett Jameson is exploring, in collaboration with Ocean Networks Canada and the Canadian Healthy Oceans Network.
