First core on deck

First core on deck

We made it to our first drill site! Because we are drilling about 500 metres (that’s 1,600 ft) and the water depth where we are drilling is about 550 metres, we will need more than 1 kilometre of drill pipe to reach our target depth we want to drill to! It takes a few hours to get the drill string down to the seafloor to begin coring. After that, 9.6 metre (or 31 ft) sections…

Life onboard our polar expedition

Life onboard our polar expedition

Much has happened in our 8 day transit from New Zealand to Antarctica. We learned about each other’s science and how we will work together in the coming weeks, hearing talks and taking tours. We crossed the Antarctic Circle and the Prime Meridian, and celebrated co-chief scientist Rob McKay’s birthday with a surprise party. Meals have been good, the gym frequented, sleep cherished. And during the transit we settled into life aboard ship. The ship…

Previous scientific expeditions in the Ross Sea (from DSP to Expedition 374)

Previous scientific expeditions in the Ross Sea (from DSP to Expedition 374)

In 2006-2007, the multinational ANtarctic geological DRILLing (ANDRILL) brought together a team of over 200 scientists, drillers, and technicians. They spent a combined six months on the Ross Ice Shelf over two seasons. They drilled 2 holes through several hundred feet of ice and ocean water to reach the marine sediments. These sediments are the memory of past climate. They contain the ice sheet history of the Ross Ice Shelf. Scientists wanted to learn more…

Imogen Browne is a Ph.D. student at the University of South Florida studying under Dr. Amelia Shevenell. Both are onboard scientists for Expedition 374, working as a physical properties specialist and sedimentologist respectively. Check out Dr. Shevenell’s blog, “Expedition Antarctica“. We will be resposting content from that blog as the expedition goes on. Follow Dr. Shevenell on Twitter at @ashevenell and Imogen Browne on Twitter at @ImogenMireille.

Exp 374 Trailer

Watch on YouTube: the Exp 374 Trailer Forty-five years ago, Leg 28 of the Ocean Drilling Program recovered cores from the Ross Sea that changed the way we think about Antarctic ice. Every decade our knowledge has advanced through more Antarctic drilling expeditions, including ANDRILL projects. Now, the International Ocean Discovery Program makes a long-awaited return to the Ross Sea on Expedition 374. Scientists from 13 different nations will look back in time to understand…

Once more beneath the Ross Sea

Once more beneath the Ross Sea

The science that the JOIDES Resolution is setting off to do is built upon decades of work done by many scientists. This began in 1973 when the first drilling ship to explore the world’s sub-seafloor story, the GLOMAR Challenger, sailed to the Ross Sea from Fremantle, Australia, on Leg 28 of the Deep Sea Drilling Project. Before we left port, we had a visit from Prof. Peter Barrett, who was one of 12 scientists on…

A landscape of ice

A landscape of ice

“So much water, so much water….” is a famous quote by our former president Mac Mahon (French president from 1873 to 1879). He would have said these words in front of dramatic flooding in the city of Toulouse. If this quote was applied to Antarctica today, I would like to switch it to “So much ice, so much ice….” Antarctica is the biggest freshwater reservoir on the planet, mainly in the form of ice. About…

Setting out on expedition 374 to the Ross Sea!

Hi everyone, my name’s Rosa Hughes-Currie and I’m a science teacher in Auckland, New Zealand. I’m aboard the JOIDES Resolution to learn more about the science aboard the ship, tell you about it, and to live my dream of sailing into Antarctic waters! Our departure from Christchurch was exciting for everyone, but especially for me as we’re leaving from my home town. Lyttleton harbour is a giant ancient volcanic crater, which is a great start…

Francesca Sangiorgi is a scientist sailing on expedition 374. She works as an assistant professor at Utrecht University. She will will be posting brief updates throughout the cruise, which will be shared here. More on her work: Dr. Sangiorgi’s main interests include eutrophication trends, natural variability vs anthropogenic changes in coastal areas, Neogene climate in the Arctic and Antarctic Oceans, Late Quaternary paleoceanography of the Mediterranean Sea including episodes of widespread anoxia (sapropels). Dr. Sangiorgi focuses on…
