New Expeditions With Pictures

ALeqM5j_fR1NPvd9GC8fqNlIe2i-SSRBIw.jpegTwo major expeditions took place in the last few months. The first explored Celebes Sea south of the Philippines from the surface to a depth 2700m.

“This is probably the center where many of the species evolved and spread to other parts of the ocean, so it’s going back to the source in many ways,” Madin [the expedition leader] stated.

The project involved the Woods Hole Oceanographic Institution and National Geographic Magazine in cooperation with the Philippine government, which also provided the exploration ship.

The most striking creature found was a spiny orange-colored worm that had 10 tentacles like a squid, Madin said. “We don’t know what it is … it might be something new,” he said.

In the second expedition, researchers from Fisheries and Oceans Canada and Memorial University of Newfoundland conducted a survey of the deep off the coasts of Nova Scotia and Newfoundland during a three-week mission in July 2007. The focus was primarily deep-water corals.
The mission revealed that life in these waters is much more diverse than previously realized. Researchers captured over 3,000 high quality photographs that displayed this diversity, including an octopus with large fins near its eyes, known as “Dumbo,” a potentially new species of scallop, and a single-celled organism previously unknown in this region

A joint team of Filipino and American scientists that explored the Celebes Sea in southern Philippines early this month, announced the marine-life discoveries following their return from their voyage Tuesday.

Second Center: Colourful coral species on a vertical cliff in the Stone Fence. The ROPOS mission uncovered coral as old as 800 years.
Third Center: This Dumbo Octopus from the Sable Gully MPA received its name because of the large fins located on either side of its head.
Fourth Center: A Basket Star embedded in Bubblegum Coral.

Craig McClain is the Assistant Director of Science for the National Evolutionary Synthesis Center, created to facilitate research to address fundamental questions in evolutionary science. He has conducted deep-sea research for 11 years and published over 40 papers in the area. He has participated in dozens of expeditions taking him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses mainly on marine systems and particularly the biology of body size, biodiversity, and energy flow. He focuses often on deep-sea systems as a natural test of the consequences of energy limitation on biological systems. He is the author and chief editor of Deep-Sea News, a popular deep-sea themed blog, rated the number one ocean blog on the web and winner of numerous awards. Craig’s popular writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web.

  1. amazing images… my indo-pacific program manager met with some of the expedition crew while passing through manila a few weeks ago… very cool that reports of findings are turning around so quickly… ocean science might actually soon give nasa a run for its money in pr for its missions… it’s this sort of public awareness of exciting near real-time science that sparks interest in youth (future scientists)…

    “This is probably the center where many of the species evolved and spread to other parts of the ocean, so it’s going back to the source in many ways,” Madin [the expedition leader] stated.

    I’d like to hear their case for that.

  3. In several conversations I’ve had over the few years with eminent barnacle biologist, Bill Newman from Scripps, we’ve talked about how the Indo-Pacific appears to be the center of diversity for deep sea barnacles. Newman et al. write in the Handbook of Deep-Sea Hydrothermal Vent Fauna

    “The center of distribution, where representatives of most genera are presently found, is in the SW Pacific, specifically the Lau Basin, Tonga. It is noteworthy that centers of diversity at high taxonomic levels in numerous other relic groups of marine invertebrates are also found in the SW Pacific.[...] the center of distribution is where availability of the vent-seep habitat has been the least interrupted in space or time, for otherwise such a high taxonomic endemicity could not have accumulated. Like the high taxonomic endemicity of the SW Pacific in general, that of the vent barnacles appears to the result of reliction due to habitat restriction rather than to barriers to dispersal per se.”
