This is Dr. Stephen Pekar, and I have been a geology professor at Queens College since 2003. My main focus of research has been investigating past climate and oceanographic changes during times (16- 45 million years ago) when CO2 was as high as what is predicted for this century (500-1000 ppm).

For the first day of the most exciting expedition to the white continent, we sailed on the eastern side of the south island of New Zealand. This provided us with protection from the high waves of the Southern Ocean that we were sure to encounter sooner or later.

Well, well, I guess we left the roaring forties only to be thrown into the screeching fifties. The first storm was just a mild blow compared to what we have just gone through. Over the last day and half, we have through a heck of a storm.

It has been over a week since we have left Wellington. It is hard to believe that so much time has past as the last week has been seemingly gone by quite quickly.

We crossed the 60th parallel yesterday and with it the seascape began to change. The huge waves that we battled in the screeching 50’s faded into smaller long distance swells that would remind us of what is waiting for us when we attempt to return northward on our way back after we finish drilling. The ocean continued to cool and with it created thick fog that would obscure ou

We started yesterday only about an hour away from our first site, the shelf site designated WLSHE-09B (WL stands for Wilkes Land and SHE stands for shelf site). It is at this site in which we had predicted to recover sediments deposited during the Greenhouse World. However, this was also the day that we sailed past a flotilla of icebergs, with some of them being miles long.&nb

While we waiting for our very first core, I thought I would introduce you to some of the labs we have on the ship. One of most favorite labs is the sedimentology lab. This is where the core is described and scanned with a photospectrometer and is high resolution pictures are taken. The last ocean drilling expedition I was on back in 2000, I was a sedimentologist and thoroughly

Reaching the First Drilling Site

The first forams!!
Once all of the commotion died down, the paleontologists went off with their samples, washing the sediments or making smear slides (smear slides are made by taking a little bit of sediments and smearing them thinly onto a slide) and then looking through microscopes looking for the tiny little shells made by microscopic organisms.
