Examining bucket of seafloor sediment collected off southeast Alaska
Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown
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.
