Dredging: Now the Fun Begins in the Lab!

A dredge is a tool used by marine scientists to take samples of rocks and sediment from the ocean floor. During the course of our cruise, five different locations were dredged for rocks- Not only rocks came up in the dredge, but so did mud!

Hot water is used to spray down the excess mud off the rocks- you can see the steam coming from the water. The air temperature was about 10 degrees Fahrenheit so a little warm water was welcome! Photo by Bogdan Onac

This picture should go with the rest of the dredging pics: Kate McMullen(middle), acting as the curator of the rocks, and shipmates Kelley Brumley (left) and Evan McQuinn look over some of the rocks and prepare to catalog them.Photo by Robbins
