It is now two weeks since I arrived back in the UK from IODP expedition 318 Wilkes Land – time to summarize our findings and bring this blog to a close.
During our two months expedition we drilled at seven sites close to, and on the Antarctic Wilkes Land continental shelf, at water depth ranging between 400 and 4000m. Despite severe weather and ice (berg) conditions, we managed to drill 3200m of sediments beneath the Antarctic sea floor, with an average core recovery of 53%. Together, the cores represent ~53 million years of Antarctic climate history. They tell the tale of an ice-free, warm greenhouse world, the first cooling around Antarctica, the onset and erosional consequences of the first Antarctic glaciers, and the subsequent dynamics of the waxing and waning Antarctic ice sheet, all the way to the thick, unprecedented ‘tree ring style’ records with seasonal resolution of the last deglaciation that began some 10,000 years ago.
It is officially done – the last core came on deck, the last samples were taken, and the last reports are now being written. Yesterday night we started our transit back to Hobart (Tasmania), where we will arrive next week. Everybody is tired, but happy about a tremendously successful expedition. We really deserve our beers in Hobart!
Enjoy below part six of the weekly video updates produced by Dan Brinkhuis (Zcene Moving Media Company). This week features paleontologist Catherine Stickley from the University of Trømso, Norway. The penguin TV actually took place in the chemistry lab !!!
A last weekly video will be finalized when we are back onshore, featuring the co-chief scientists.
Part FIVE of the weekly updates from the JOIDES Resolution, sailing for the Antarctic coast of Wilkes Land between January and March 2010. Our mission: exploring the climate history of Antarctica. This week features sedimentologist Rob Dunbar from Stanford University. Enjoy!
Enjoy the next episode of our weekly videos! This week is featuring James Bendle, an organic geochemist from the University of Glasgow.
And here is the third episode of our weekly videos from the Wilkes Land IODP expedition. This week is featuring Saiko Sugisako, a palaeomagnetist on the ship, and also my room mate. Enjoy!
Part TWO of the weekly updates from the JOIDES Resolution, drilling off Antarctica to explore Antarctic climate history.
This week the video by Dan Brinkhuis features a portray of Dr. Jörg Pross, a micropaleontologist of the Frankfurt University.
One of the participants in our endeavor to explore the climate history of Antarctica is the videographer Dan Brinkhuis (Zcene Moving Media Company). He has probably been one of the most busy people during our first week of transit, as he is constantly running around with his camera trying to capture all the different activities on the ship.
Today his first weekly report from the JOIDES Resolution came out featuring a portray of IODP expedition project manager Adam Klaus. Dan will produce reports like this for every week of our expedition, featuring different people on the ship and their roles in this expedition.
Enjoy the expedition trailer…
