Examining bucket of seafloor sediment collected off southeast Alaska

Detailed Description

USGS research geophysicist Danny Brothers (right) and colleagues examine the surface of a sediment grab sample just pulled onto the deck of the Canadian Coast Guard Ship John P. Tully. The sample was collected from the top of a mud volcano north of the border between southeast Alaska and British Columbia. Expedition scientists are investigating the Queen Charlotte-Fairweather fault to better understand its history and the hazards it poses to coastal communities in the U.S. and Canada.
