Here's some interesting #sciArt for ya. These great gouge marks are left behind when a large iceberg drags across the bottom of the seabed. A large collection of these images has just been published, with the help of 250 scientists from 20 different countries. By gathering this high-resolution atlas of the seafloor, scientists can better determine how the climate is changing.
