I'm sitting here waiting for the bus to take the science party to the hotel. It feels really sad to be leaving all the people who have been my family for the last 8 weeks.

I can't believe that in 26 hours we'll be in our berth in the harbor in Wellington. I worried when I got on board that the time would drag and that 8 weeks would feel like an eternity.

Happy New Year to everyone! We rang in the new year on the bow of the ship.

It's early morning of December 31 here on the ship. Things are quiet right now because we're waiting for the gale force winds to die out and the sea to calm so we can start drilling again. We had to suspend drilling early yesterday afternoon because of the swells.

Well, Christmas is over and all the festivities are behind us. Celebrating the holidays on the ship was amazing. We had a gift exchange on Christmas Eve, where I received this cute stuffed sheep, which will forever remind me of New Zealand!

The picture above shows a cutting shoe for an The Extended Core Barrel (XCB) coring system is used in sedimentological, climate, and paleoceanographic studies.The XCB is used to recover 9.5 m long core samples from soft to moderately hard formations. The XCB is typically deployed when the formation becomes too stiff to piston core (i.e., upon piston coring "refusal") or when it is not hard enough to permit efficient recovery with the Rotary Core Barrel (RCB). The XCB cutting shoe extends ahead of the main bit in soft sediments but retracts into the main bit as the weight on bit increases when firm lithologies are encountered. The XCB uses the same bottom-hole assembly (BHA) as the Advanced Piston Corer (APC).">Extended Core Barrel (XCB) drill bit. On this expedition, we have alternated between 3 types of drill bits. The XCB, Advanced Piston Coring (APC) and Rotary Core Barrel (RCB). Each bit and cutting shoe is best suited to a certain kind of sediment and set of drilling conditions. The APC is best for soft sediments and is

When the cores are being described by the sedimentologists, they need to know more than just color and visible structures. They need to know what minerals the grains are made up of, and if there are any remains of organics, such as plants and animals.

Once the samples have been taken from the working half, and the archive halves of the core have been described, they have to be packed and stored so they will be ready to ship when we reach port.

We've had a very eventful few days on the JR - geologically speaking! We've set a record (another one!) and we've hit our target for this drilling site.
