Preparing mooring for deployment

Detailed Description

USGS oceanographer Kurt Rosenberger prepares a mooring for deployment from the research vessel Rachel Carson on October 6, 2015. The tan, cone-shaped instrument is a sediment trap. Near the far end of the trap is a CTD (with small red tag) for measuring seawater conductivity (related to salinity), temperature, and depth. The line held additional instruments, such as current meters, not shown here.
