First Volcano
September 12, 2012

The Submarine Ring of Fire 2012 NE Lau Basin exploration team onboard the R/V Roger Revelle continues towards its second target site, S. Fonualei. A live webcast was conducted from the ship with The Exploratorium in San Francisco, a world-renown museum of science, art, and human perception. The webcast highlighted the reasons for exploring the most volcanically-active region of innerspace, the ocean, with the Quest 4000. This webcast followed a series of webcasts conducted by The Exploratorium focusing on the Mars Rover, curiosly, as it explored the surface of Mars.

Later in the morning, the science team met with the ROV team for an overview of the capabilities and assets of the vehicle, as well as a brief on the display screens in the ROV Video Viewing Lab and the ROV Van. Using multibeam sonar today, a new underwater caldera was discovered and dubbed First Volcano. The water column above the caldera was sampled with the CTD.
