Meet the scientists and their underwater drones tackling the 'weirdly complicated' world of ocean carbon

Meet the scientists and their underwater drones tackling the 'weirdly complicated' world of ocean carbon

It's that rarest of rare conditions along coastal Newfoundland: a dead calm day. By 7 a.m., the crew aboard the fishing boat Belle of the Bay are taking full advantage of it, steaming out of the harbour in Heart's Content under dazzling July sunshine, with their sights set on a prized catch in the middle of Trinity Bay. It's not fish they're after. The object awaiting them looks like a mashup between a torpedo, a banana, and a Dash 8 — a type of underwater drone, called a glider.

The world's permafrost is rapidly thawing and that's a big climate change problem

As we work to curb emissions, another source of greenhouse gases is coming to the surface. An international study released this fall shows that permafrost thaw could contribute as much greenhouse gases to our atmosphere as a large industrial nation by the end of the century. In the Arctic, warming is amplified, with annual temperatures having warmed 2.3 C since 1948, more than twice the global rate, according to Environment and Climate Change Canada.
