We study processes that form and modify volcanoes in the sea
Volcanic eruptions and flank collapses are significant geologic hazards. Our goal is to better understand these and other volcanic processes in the deep sea environment. Through this research we hope to gain insight into potentially destructive eruptions on land or in shallow water. We are studying:
- Style of volcanic eruptions at varying depths and lava compositions
- Explosive volcanism in the deep sea
- Submarine landslides and the structure of the flanks of volcanoes
- Evolution of hydrothermal systems
- Plio-Pleistocene paleoclimatic history recorded in drowned coral reefs
- Origin and evolution of oceanic volcanoes
- Biogeography of ocean islands and submarine volcanoes
Our research is highlighted in these web pages
To study these processes, our research takes us to places such as Hawaii, the Gorda Ridge, and the seamounts off California. These places are characterized by different types of volcanism: hot spots, mid-ocean ridges, and intraplate seamounts. We also work off the West Coast studying geologic processes unrelated to volcanoes.

Why is this research important?
Submarine eruptions are poorly understood.
Why?
There are many advantages to studying samples erupted under water.
What are they?
What is it like to explore the deep sea?

We send back daily cruise logs from our expeditions. These logs contain dive reports written by the scientists, images, maps, and updates from the others in the crew. Latest cruise logs: Seamounts 2007 and NeMO 2007 How do we explore the deep sea? Here is information about the equipment we use. |
