Catch of the Day

November 15, 2013

R/V Knorr Bosun Peter Liarikos and Shipboard Scientific Services Group technician Amy Simoneau release a catch of rock specimens collected with a dredge near the Mid-Atlantic Ridge. Scientists on the ship also gathered data using multibeam bathymetry, magnetic and optical sensors, and CTDs on the autonomous underwater vehicle Sentry; and cameras on the WHOI TowCam. Their goal was to better understand the formation and evolution of detachment faults and how those faults relate to the supply of magma along the ridge axis.
