Thriving coral gardens and ash-white coral graveyards discovered by international team of researchers in hidden canyons off Australia's coast.
In their recent voyage, McCulloch and his colleagues aboard the research vessel R/V Falkor explored the depths of three canyons on the South Australia coast — Bremer, Leeuwin and Perth canyons — descending for the first time into each area's abyssal zone, or the dark depths roughly 2.5 miles below the surface.Beyond the obvious reason for such exploration, scientists are interested in these submarine crannies because they sit on the front lines of oceanic climate change.
During their latest expedition, the crew of the Falkor learned that these canyons are bustling with life deep underwater. Each spot hosted lush gardens of coral, rich with marine life and bursting with color. However, each canyon also contained extensive pockets of dead and fossilized coral. According to the researchers, these corals bear the record of both recent, anthropogenic ocean warming, as well as longer-term changes to the world's climate.
This voyage was funded by the nonprofit Schmidt Ocean Institute, and the team's newest research has yet to appear in a peer-reviewed journal.
