What can we learn from Earth's magnetic field?

While we're casing and preparing to core Hole G at Site U1480, as Agnes wrote about in her recent post, the scientists are mostly working on their reports and discussing their initial interpretations. We have a bit of down time, and we wanted to make use of the great movie lounge downstairs. We watched the geo-fiction movie, The Core.

Today in Geology History: In Memory of Marie Tharp, Pioneering Oceanographer

Think of the first time you saw a map of the world. It probably looked like colorful patches mostly connected to other colorful patches, with a vast scape of blue between the colorful areas. Until the 1940s, that’s how many people imagined the ocean: “a uniform, featureless blue border for the continents.” We commemorate Marie Tharp with a photo of many of the women on the current research cruise of the JR and a brief summary of her work, which includes creating the first seafloor maps of the world's oceans and establishing the global distribution of mid-ocean ridges.
