Keeping Ties on Jenny

3002kic3.jpg

Kick ‘em Jenny is a 1300m submerged volcano residing about 8km off the Grenada coast and the only live submarine volcano in the West Indies.  In 1939 an eruption here rose 275m above the ocean surface (see image below fold).  Eruptions have been both explosive and simply lava flows and domes in the summit crater.  Nearby residents often hear deep rumbling noises. A team from WHOI installed a seismic monitor over Jenny 250m below the surface.  The instrument package will be moored to a surface buoy with a high-frequency radio (and solar panels) to send data to the village of Sauteurs on Grenda.

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. Is this baby being monitered primarily because of the hazard it presents? Or is it just a good place to study sub-surface volcanism?
