In Transit

The horizon doesn't change much as we transit through the Indian Ocean at 14 knots (25 kmph=16 mph--this is very fast for a ship of our size). We're motoring at a bearing of 103º from port in Colombo, Sri Lanka, to our drill sites in the eastern Indian Ocean. We should get to our first site tomorrow morning. In the meantime,

Core Description Consensus

Coordinating scientific observations among 33 scientists and 24 lab technicians over 2 shifts is no easy task. But it’s very important.

Core on Deck!

We got our first core on deck this morning at 2am ship time!  It was a slurry of dark grey, muddy and sandy sediment that glistened under the catwalk lights.  Everyone on shift came to crowd around--at a safe distance, wearing hard hats and safety glasses, of course--and see the first glimpse of what we're after.  The second core is already on its way through tests for properties

50 Years Ago Today in Geology...

Fifty years ago the world looked very different to geologists. Not only was most television still in black and white, but the Grand Unifying Theory of Plate Tectonics had not yet been unified.

Sampling Sampler

After the core comes on deck at the catwalk and whole-round samples are taken for fossils and chemistry, it comes indoors for the rest of its life. Then measurements and sampling really get underway.

A few tidbits about life on the JR

Aside from the gentle rocking motion, the 12-hour shifts, the vacuum toilets, the noise of 12 thrusters keeping us in place, and the 360º view of a completely flat horizon, it's just like living on land.

Biscuits and Gravy

Drilling can alter the core in a variety of ways. This morning, the core on the description tables is made of "biscuits and gravy": coherent chunks of compacted sediments separated by a muddy matrix of ground up core that gets squeezed into the core barrel in between the biscuits. Why does this happen and what can it tell us?

The best room on the ship

You can argue about this--perhaps the Core Lab, the Chem Lab, the Gym, one's own cabin--but I think the best room on board is the Mess Hall or Galley. The place we enjoy all our meals and cookie breaks together.
