What are you doing in the middle of the Pacific?

So, a fair question to ask is "what are you doing out there in the middle of the Pacific Ocean poking holes in the seafloor?"  I suppose the easy answer is "because we want to." We want to not as much for the hole it makes, but for the sediments that we drill and recover when we make the hole.  These sediments have been piling up out here for millions of years.

The Dope on Isotopes

So for younger readers, I should probably start off by explaining that I am using the word "dope" in the mid-twentieth century, American usage of the word, when for a couple decades hipsters used it to mean "information." Lessons on archaic slang aside, it was interesting to learn yesterday that the average temperature of the earth from the ancient past can be determined by

My own private Pacific island.

I have always wanted my own pacific island. I just never figured that I would get it. We are still on station due to the lack of berthing space in Victoria, BC.  We are due in on the morning of July 5 but we were hoping that we might get an extra night in port. We are still working and having fun onboard and will continue to do so.

First entry: Introduction

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).

Clearing the south island

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.

Out of the Roaring Forties and into the Screeching Fifities

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.

Entering the mysterious waters of Antarctica

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

Its Always More Difficult Doing it in Antarctica

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

Interesting story on NPR today!

As Exp 346 sets sail today, there was an interesting story on NPR this morning highlighting climate change and featuring an interview with Exp. 342 chief scientist Dick Norris. Read - and listen - to what he had to say here!
