Ben Grupe (left) prepares the conductivity, temperature, depth (CTD) bottles for deployment. This is one instance when being tall comes in handy. Normally, scientists have to climb onto the white frame to cock the bottle caps. As the CTD is lowered into the ocean, a computer monitors the data and orders bottles to snap shut, collecting water samples from different depths.
