Collecting a piston core of seafloor sediment off British Columbia

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

Detailed Description

Scientists prepare to lower a piston corer off Haida Gwaii, British Columbia, to sample seafloor sediment near the Queen Charlotte-Fairweather fault. Expedition scientists are studying layers of sediment in the cores they collected to identify and determine ages of past earthquakes along the fault. This information will help them assess future threats to coastal communities in the U.S. and Canada.
