Departure from WHOI dock on Knorr cruise KN223 from 10/26/2014 to 12/02/2014. This is the final scheduled WHOI science cruise for Knorr and the Long Core system.
Cruise Chief Sci is Steven D'hondt of the University of Rhode Island.
The science objectives of this cruise will be long piston coring, gravity coring, multi-coring, CTD/Niskin operations; multi-beam and 3.5 kHz mapping of sites; shipboard studies of interstitial water chemistry; shipboard core logging; shipboard sampling for geochemistry, microbiology, paleo-oceanography.
Image Of the Day caption:
Youre looking down the barrel of the Long Core on the starboard rail of the research vessel Knorr. This one-of-a-kind instrument was developed at WHOI to extract plugs of sediment from the seafloor and can take cores up to 150 long--twice as long as conventional coring devices. Sediments contain physical and chemical clues to ocean conditions and climate thousands to millions of years ago. These collect over time, so longer cores generally contain information that extends further into the past. Knorr required 50 tons of new equipment and significant modifications to deploy and retrieve the Long Core.
