Research that demonstrates low oxygen levels in the depths of Saanich Inlet might seem like concerning news; after all, marine life needs oxygen to survive. But on a planet facing climate change, this is also good news: without oxygen, the organisms living on the seafloor, or benthos, can't decompose, thus reducing the amount of carbon that cycles back to the atmosphere as carbon dioxide, a powerful greenhouse gas. New research using ONC's cabled ocean observing infrastructure provides further evidence as to why this deep Vancouver Island fjord is a natural place that stores carbon, also known as a carbon sink.
