On Wednesday and under an intense bright sun and blue sky we finally departed the dock at Hong Kong's Kennedy town and headed for the open South China Sea. Victoria Harbour was extremely busy with hydrofoil ferries rushing backwards and forwards between the mainland, Macau and the islands.

Our first proper day at sea and I awoke with the rather pleasant sensation of the ship rolling gently which is a marvelous and comforting feeling when lying cosy in your bunk, but today was not a day for a long rest because we had already been told that at 10:30 this morning they would be our first lifeboat drill, an essential part of the safety of any major seagoing vessel.

To say the life of a staff scientist at the start of an IODP expedition is busy is a serious understatement! I could easily work 24 hours a day and still not feel like I am caught up. Fortunately, there are so many experienced technical staff and scientists on the JOIDES Resolution that most things would get done even without me.

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.

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.

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.

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.

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.

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.

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.
