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
• Frequency and volume of mid-ocean ridge eruptions
• 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

Latest cruise logs: Gulf of California, Leg 7
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.

How do we explore the deep sea? Here is information about the equipment we use.

How do we map the seafloor?
