Our teacher for this one has been down in the ALVIN Submersible to collect samples! The core is beautiful - has iron, pyrite, sulfer - all kinds of beautiful veins, and patterns. A lot of chemistry today. Got to see a couple porpoises this morning swimming and jumping port side of the bow - no photos as the waves are still BIG and coming over the side.

I have been asked about volcanoes as we are currently in the Bering Sea very close to the Aleutian Islands which are made up of a long chain of volcanoes, so I thought I might write a few words. I have been interested in volcanoes for almost 30 years and I have been lucky enough to travel around the world to see and climb many of them. Most of my research has been looking at the material that Australian volcanoes produced 300 to 400 million years ago. These volcanoes are long gone but we can still read the story of their eruption in the deposits they leave behind.

Hi! Back again with some more info about volcanoes. Last post I talked about stratovolcanoes like the one in the image to the left called Mount Saint Helens. This time we'll look at shield volcanoes and the most destructive type of volcano, the caldera.

If you look at the picture that accompanies this blog, you will notice that just to the left of the Louisville seamount trail is a dark blue line that runs all the way down to New Zealand. That line is a boundary. To the left of it all the volcanoes (and there are a lot of them) are in the Pacific Ring of Fire.

Right now the JOIDES Resolution is drilling into a mountain that is over 4000 meters (13,000 feet) tall. The mountain is actually underneath me in the photo, but can you tell it is there just by looking at the ocean?

One of our main research objectives for drilling the Louisville seamount trail is to try to better understand what is happening in the mantle underneath it. Volcanoes and earthquakes are our most dramatic reminders that the inside of the Earth is not a static ball of rock: there is a fluid mantle that is causing the seemingly solid crust beneath us to move and change.

If you lived your life like a volcanic island, you would spend a long time growing without anyone knowing you were there, have an explosive debut into the atmosphere, continue growing but become much less explosive resulting in a bunch of resort hotels being built all over you, become so heavy you make the ground sink underneath you until you disappear from view and then end your life by fallin

One advantage teaching science has over pretty much all other subjects is the ability to bring in cool demonstrations and hands-on activities to introduce and reinforce concepts.

Someday, seventy million years from now when the cockroach people are the dominant species on the planet, they are going to have their own marine research drilling program and are going to be drilling on a seamount whose top is 1,500 meters below the surface, and are going to be surprised when they discover a sedimentary core that has a Don Ho record in it, because it turns out the seamount is

Meet the chief scientists for our Expedition, Dr.'s Anne Le Friant (follow her blog) and Osamu Ishizuka. They have collectively written the script for this exploration developed through the scientific review process.
