Preparing for the adventure

First time I heard about the JOIDES and the IODP was during my bachelor on Geology, in Salamanca, some years ago. During their classes, professors José-Abel Flores and Francisco Sierro often talked about their experience during the several expeditions they joined.

First Core!

It took its time coming and kept getting delayed but like many exciting things worth waiting for the first core finally arrived late but on deck about 1 AM last night local time. We had spent a rather unfocused day completing our reports with the high point being a rather excellent Chinese dinner to celebrate the new year largely made by members of the Chinese scientific party.

Core Mayhem

A little later than we expected, but the first core has arrived and after a suitable period of rest and heating to room temperature the core was split and the serious work could begin at last.

Getting into the routine

Second day of successful core recovery and we are now getting the hang of the various systems both human and mechanical around the lab that let us get our work done.

Smoother going

Today has been a much smoother day of operations for us in the core lab now that we are getting used to the equipment, the software and indeed each other. The day started well with a small group meeting (pictured) just to touch base and see what had happened in the past 24 hours.

Deeper and Deeper

We are now almost half way to basement here at Site U1431 and the hole is fighting us a little as we make progress. Recovery, the proportion of sediment that is actually brought back to the surface compared to how much the drill advances, has fallen away and we are in a lean period. Experience suggests however, that this is a passing phase that can be caused by number of things.

Mysterious sand

Slow but steady progress today on the ship.  We are bringing up small volumes of sand that was largely unexpected in such a deep water setting, especially given the earlier results from the southern Chinese continental slope courtesy of ODP Leg 184 -- which showed only clays in deep water.

Between a rock and a very hard place

We awoke today to bad news about the drilling.  Just after midnite the drill bit encountered an especially hard object and suffered a catastrophic failure, so that the drilling bit and “shoe” (see photo) were lost from the end of the pipe and dropped into the bottom of the hole.
