Rare glass sponge reefs on B.C. Coast to star in live streamed expedition

People around the world can catch a glimpse of the rare glass sponge reefs found in the B.C. waters over the next week orso.

A team of scientists will be live streaming research conducted deep underwater in Hecate Strait.

The kind of glass sponge found in B.C. was thought to have died off 40 million years ago untilfragile living reefs were discoverednear Haida Gwaiiin 1987.

Earlier this year, the federal government created a Marine Protected Area tohelp conservethem.

But scientists need to know more about the reefs to provide that protection, saidStephanie Archer,a post-doctoral fellow with Fisheries and Oceans Canadabased in Nanaimo.

"One of the things that comes with being a marine protected area is increased monitoring and protection from Fisheries and Oceans," she said.

"Until we know how the ecosystem works, and what it looks like when it is healthy, we won't be able to know what we should be looking for signs of it not being healthy."

Expedition live stream

Starting on May 12, the expedition team will use a remotely operated vehicle to explore the reefs deep underwater in Hecate Strait.

The researchers will blog and live stream video of the reefs as they explore them.

"Because they are so deep and so remote, opportunities to study them have been few and far between," said AlexandraBarron, theocean conservation manager for the Canadian Parks and Wilderness Society in B.C.

"Live streaming this expedition brings the public the opportunity to see these sponge reefs come to life before their eyes and actually see what the scientists are working on."

Sponges may look like plantsor even geological formations, but they're actually animals among the oldest branches of animal life on Earth.

Glass sponges build skeletons out of silicaor glass, and some including the species on B.C.'s coast are great reef builders.
