Dan Powers, aboard the Bold Horizon, prepares to deploy a piston core over the Cascadia Subduction Zone, off the northern California coast.

The M/V Bold Horizon, operated by Eclipse Group, Inc., was contracted by the USGS to support the collection of piston cores and geophysical survey data along the Cascadia margin.
