Coffee Master

No day on the ship can be completed by mere mortals without a decent cup of coffee to give strength and energy and especially so after 4 weeks at sea.

Congratulations Lisa!

Today was a very special one on our expedition because we received news that our paleomagnetic expert Lisa Tauxe, who is a Professor at Scripps Institution of Oceanography,  and a veteran of scientific ocean drilling had elected to be a member of the National Academy of Sciences in the United States.

Sunrise patrol

It is easy to spend all day every day inside in the laboratory and so it is nice that we take opportunity to go out and look at the rising sun over the Indian Ocean every day after breakfast. It has been quite cloudy until this point but over the last couple of days we've had good luck and the sunrise has been clear, or at least as clear as can be expected in these latitudes.

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.
