Keeping Ties on Jenny


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, a National Science Foundation supported initiative. He has conducted deep-sea research for 20 years and published over 50 papers in the area. He has participated in and led dozens of oceanographic expeditions taken him to the Antarctic and the most remote regions of the Pacific and Atlantic. Craig’s research focuses on how energy drives the biology of marine invertebrates from individuals to ecosystems, specifically, seeking to uncover how organisms are adapted to different levels of carbon availability, i.e. food, and how this determines the kinds and number of species in different parts of the oceans. Craig’s research has been featured on National Public Radio, Discovery Channel, Fox News, National Geographic and ABC News. In addition to his scientific research, Craig also advocates the need for scientists to connect with the public and is the founder and chief editor of the acclaimed Deep-Sea News (, a popular ocean-themed blog that has won numerous awards. His writing has been featured in Cosmos, Science Illustrated, American Scientist, Wired, Mental Floss, and the Open Lab: The Best Science Writing on the Web. His forthcoming book, Science of the South (, connects cultural icons of South such as pecan pie with the science behind them.

  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?
