So, I’ve talked about what we do once we have 'core on deck’. But, how do we get core in the first place? Yesterday, the scientists had a tour of the Rig Floor, so we got to learn all about the drilling process.

Today I'll show you a bit of the working space I have here on the JOIDES Resolution, specifically the cold room where I culture subseafloor microbes. Come on in, and bring a jacket!

Here you'll learn what the heck the subject of that picture is, and why it's important to IODP Expedition 330. Isn't it pretty?

Did you realise that we have a big hole in the bottom of our boat? Its hard to imagine that a boat can float with a hole in its bottom, but there has to be somewhere for the drill string to pass from the derrick to the sea floor. This big hole is called the moon pool and on rare occasions like the other day, we get to see the moon pool completely open.

We know that there are microbes living in the rocks below the seafloor, but very little is known about how quickly they reproduce. Here I talk about one way I am trying to learn the answer to that question.

Obtaining clean samples from seafloor drilling can be a challenge- the drilling itself pumps massive amounts of surface seawater into the borehole as lubricant for the drilling machinery. This seawater contains lots of potentially contaminating microbes, such as phytoplankton (who have no place living in the dark subseafloor!), but there's no way around using it. Luckily, there are ways of checking to see that your samples are not contaminated, and I discuss that here.

Life can be dangerous for those who work on the sea- especially if you are an iPod. I narrowly escaped losing my iPod to the crack between my bed and the wall- in today's blog post I recount this harrowing adventure!

In today's blog, I'll walk you through my sampling process- I realized I've shown some of the experimental methodology I use out here, but nothing about how I get to that point. That's what I'll cover here.
