Beautiful Saturday morning, the sun was already hot at 8 am. The scientific party must still be patient… We are continuing our efforts to get through an obstruction in the hole at ~900 meters below the seafloor.

Here's Damon Teagle, co-chief of Expedition 335. He was also co-chief of ODP Leg 206, and IODP Expedition 309, two of the three previous cruises at site 1256. Damon and Doug Wilson (also co-chief of ODP Leg 206, and lead proponent of the original proposal) are the two scientists who have participated to all cruises at site 1256.

This graph shows the total number of boreholes that were drilled and cored deeper than 100 meters in oceanic crust (oceanic plateaus and passive margins are not counted here) since the beginning of scientific ocean driling in 1968. These 34 holes represent less than 2% of the 332 kilometers of cores recovered since DSDP Leg 1.

Please forgive the somehow outrageous processing of this photo; it probably reflects our more colorful perception of everything since we went down to the bottom of the hole (1507.1 meters below seafloor) yesterday morning at about 9 am. Smiling faces are back in the labs; everybody is ready.

The JOIDES Resolution is currently drilling in a hole that has already been drilled during three previous expeditions.

This morning about 6am, a funnel cloud was spotted off the port side of the ship. The captain kindly made an announcement over the PA to let us all know about it, so that we could go outside to take pictures (or to just enjoy the moment).

In this blog, learn about an activity that allows high school age students to use real data from previous JOIDES Resolution research expeditions to compare the spreading rates in different areas of the seafloor and find out how fast is “superfast.”

After 16 days of perseverance, we got our first core on deck this morning at about 8:30 am. These two weeks of reaming, cleaning, cementing, and reaming and cleaning again have been long, and sometimes a bit stressful. I can see a lot of smiling faces around; it looks like we will now eventually be able to deepen Hole 1256D.

The seafloor is spreading! The seafloor is spreading! To find out what this means, read on.

Yesterday, as Benoit said in his blog post, we got our first core on deck. It's always been true in scientific ocean drilling that it takes a tremendous team effort to successfully recover cores from deep beneath the ocean floor. And nowhere is that more the case than with hard rock drilling.
