From Planning to Reality - II

From Planning to Reality Continued...   One needs to spend a lot of research time to then figure out the best possible strategy, and eventually the best possible location, to answer the questions we came up with; and the next couple of years were spent with detailed reconstructions of plate tectonic movements and water depths.

Plate Tectonics Works

We have just arrived at the last coring Site for this Integrated Ocean Drilling Program Expedition ("PEAT-6C", from today also know as Site U1335), with three more planned as part of this science programme for our colleagues on the next Expedition.

Find Out Which of the World’s Volcanoes are Erupting Today, Today!

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.

Make a Seamount Trail in the Classroom

Learn about a hands-on activity that can help students visualize how a hotspot and a moving plate can create a seamount trail.

Hands-on Ways to Visualize the Earth’s Layers

Even though we are drilling into rock above the ocean floor, our main objective is to understand better what is happening inside the earth’s mantle. Here are a couple activities that can help students visualize the Earth’s interior in a hands-on way.

The Puzzle of Tectonic Plates

To understand the science of our expedition, students need to know that the Pacific Ocean plate is moving over a hotspot to create the Louisville Seamount Trail. This may be hard for students new to the concept to understand, particularly since most of them probably associate the word “plate” with dinner accessories.

Seafloors Surfing the Asthenosphere (or, What is Seafloor Spreading, Anyways?)

The seafloor is spreading! The seafloor is spreading! To find out what this means, read on.
 

Exotic Alaska

Alaska is exotic, and it's not because there are scantily-clad Alaskan’s everywhere. To the contrary, the population density of Alaska is approximately 1 person per square mile (and they’re probably bundled up most of the time)!
