Dirty glaciers all over the world

Dirty glaciers are the most understudied kind, Truffer said. Scientists have not accounted for their quirky properties in models. Those numbers are important because so many people depend on glacial melt as their water supply, including millions in India, China and Bangladesh.

Postcards from a frozen icebreaker – Part 8

Crack by our tower widened today, but things are still stable. It’s up to 1m in places. The rest of the area went through a major shift. Satellite maps show a large region of shear and that shear basically ripped our flow in half just outside the outer wall of the Fortress.

Scientific endeavors have revealed some eerie places and a symphony of scary sounds from all over the planet — everything from bellowing sand dunes and whistling lightning, to groaning ice shelves of Antarctica. We got them here in our 2019 Halloween playlist.

Postcards from a frozen icebreaker – Part 6: cargo & polar bears

…Then this evening the mom and cub showed up again. Meandering across the ice and right through Met City where we had been about 20 minutes prior. They walked the power line and messed with an ice sensor.

Google Earth and a simple model explain a weird pattern seen in LiDAR hillshade

Is this a bizarre and gigantic fossil discovery? An unsolved mystery akin to the face on Mars? Unfortunately, this is just another set of compressional folds within the Appalachian Valley and Ridge, but they do stand out in the hillshade due to their interesting topographic pattern.
