Joint expedition focuses on amazing coral gardens off Big Sur coast MBARI marine biologist Jim Barry briefs the science crew during the June 2016 expedition to Sur Ridge.

The researchers are using MBARI’s remotely operated vehicle (ROV) Doc Ricketts and its host vessel, the Western Flyer, to collect video and samples from the slopes and crest of Sur Ridge. They are trying to understand why this area is such a favorable habitat for corals and how fast the corals are growing. Some of the deep-sea corals on Sur Ridge can live for over a century. To follow this exciting expedition, check out the background information and daily blog entries on the sanctuary website.

On the second-to-last day of that expedition, the researchers had a little extra time, so they decided to do an ROV dive on Sur Ridge. They were surprised and delighted to discover that parts of Sur Ridge were home to large numbers of deep-sea corals and sponges. Intrigued, they returned to the area in June 2014 to explore more of the seamount, and found even more impressive coral gardens. During the current expedition, the researchers plan to conduct a series of biological surveys across different parts of Sur Ridge, including areas that have never been seen before. This will help scientists get a better idea of the full diversity of habitats and animals that live on this fascinating underwater mountain. Share Like this? Share it!
