Active submarine volcanism on the Juan de Fuca and Gorda Ridges in the NE Pacific
- Working with the NOAA/VENTS program to document and study recent volcanic eruptions, including the 2011 eruption at Axial seamount.
- Working on the development of new seafloor instruments to detect and monitor submarine volcanic eruptions. Much of this work has been done at Axial Seamount, first as part of NOAA's New Millennium Observatory (NeMO), and now as part of NSF's Ocean Observatories Initiative.
Exploration of active submarine volcanoes in the Pacific Ring-of-Fire, including:
- Explorer Ridge in 2002
- Marianas volcanic arc in 2003 and 2004 and 2006 and 2009 and 2010
- Kermadec volcanic arc in 2005
- NE Lau Basin in 2012
Monitoring and geological studies of active volcanoes on land
- Campaign GPS monitoring networks on Fernandina and Sierra Negra volcanoes in the Galapagos islands, and a continuous GPS network on Sierra Negra.
- Previously worked at Mount St Helens volcano in Washington, Kilauea and Mauna Loa volcanoes in Hawaii, and on the active volcanoes of New Zealand

NOAA's Ocean Exploration web site includes photos and movies from our Submarine Ring of Fire expeditions. Be sure to check out the movies from the 2006 expedition when we saw an underwater volcano erupting and red rock on the seafloor! You might also want to check out the Magic Mountain Virtual Site.
The NeMO web site - a compilation of research at an active underwater volcano (Axial seamount, off the coast of Oregon and Washington). NeMO Explorer has virtual views of the seafloor, fly-through movies, virtual panoramas and lots of video clips. NeMO Dive! lets you make a simulated dive to the seafloor with a remotely operated vehicle. There is also Educational Curriculum available on the NeMO web site.
The VENTS Program Multimedia Page has additional video clips.
