Breakfast of Champions

A vigorous day of action in the core lab requires proper nutrition and what better place to find it than in the galley of the ship.

Marking time

One thing all geologists want to know is the age of the rock they are looking at and the most common way of doing that is by looking at the fossil assemblage in the sediments. When working with a thin core from the bottom of the ocean as we do here we are obviously not likely to find a fossil horse or a dinosaur but instead we rely on microfossils that represent the ancient plankton of the ocean.

Geophysical Correlations

We are now drilling at deeper than 700 m below the seafloor but in the upper part of the section we have a number of holes that now allow us to put together a relatively complete record of sediment in this area provided the different drills cores can be related to one another.

Measuring the reversals

Today we continue to penetrate deep into the section and have reached rocks of around 8 million years age. Critical to determining the age of sedimentation is the magnetic timescale which is worked out by two scientist on the ship , Lisa Tauxe from the Scripps Institute of oceanography in San Diego and Giancarlo Scardia an ex-patriot Italian now working in San Paolo Brazil.

Back in business

A new day brings new core to our sediment hungry science party.

Salute to the techs!

Today we are still waiting to get back to coring as the final stages of re-entering the hole after the casing is completed. This gives us the chance to thank our valiant technical staff that help keep all the labs running smoothly on a daily basis.

Dinner is served

Bowl Decoration Activity

हम छेद U1456D पर आगे Coring परिचालन शुरू करने के लिए इंतज़ार कर रहे हैं। इस बीच, हमारे वैज्ञानिक अपने प्रारंभिक रिपोर्टों को पूरा करने की कोशिश कर रहे हैं।

Re-entry Cone Deployed

It had been put together a few days ago but today was the day that the re-entry cone was finally deployed and made its journey down to the bottom of the sea floor ready to help us fit the casing and also to enter and reenter the hole several times.

The Underreamer

We are now at Hole D (the fourth hole at our site) and preparing to set casing so that we can drill very deep and sample some of the igneous basement here in the Laxmi Basin.
