One of the best moments that I witnessed this season while watching the Nautilus Live stream was back in July during the Pacific Seamounts Expedition off of Haida Gwaii.
The team came upon an amazing coral field that featured this GINORMOUS coral that could be 100s to 1000s of years old based on deep sea growth rates. I wish I had better pics than screengrabs but once the expedition wraps up Nautilus will be releasing all the best quality images.
