Ice (Re)Cap: August 2016

From Antarctica to the Arctic; from polar caps, permafrost and glaciers to ocean-rafted sea ice; and from burly bears to cold-loving microbes, fascinating science is found in every nook and crevasse of Earth’s cryosphere, and new findings are announced often. Here are a few of the latest updates.

Illustrating Geology: Great images that transformed the field

“The Map” is perhaps the single-most recognized depiction within geology, but it is just one of many historically transformative images in a field that relies heavily on illustration and visualization to help convey information and shape our understanding of the natural world.

Seeing the seafloor in high definition: Modern mapping offers increasing clarity on Earth's vast underwater landscape

Advancements in seafloor mapping technology have allowed us to see through the water with increasing coverage and resolution. But only a tiny fraction of the seafloor has ben mapped in high resolution, leaving vast expanses of the deep ocean virtually uncharted.

Radar reveals unmarked graves

The occasional excursion to Death Valley or mineralogical study of bloodstone notwithstanding, geoscientists don’t often delve into the macabre in the course of their work. But when the administrators of two cemeteries in western New York came calling in 2014, researchers from Buffalo State College ended up using their geophysical field skills to hunt for centuries-old graves.

'Hot Jupiter' atmospheres come into focus

Imagine the planetary lovechild of Jupiter and Mercury — but even larger than the former (usually) and much closer to the sun than the latter — and a picture will emerge of so-called “hot Jupiters,” a class of huge, sizzling exoplanets that typically take just a few Earth days to orbit their parent stars. Not much is known about these mysterious worlds, only recognized since the mid-1990s, but new research is helping improve our understanding.

Turtle finds lower Altiplano elevation estimate

Rare turtle fossils uncovered in Bolivia suggest that, about 13 million years ago, the southern portion of South America’s Altiplano — the arid, high-elevation plateau immediately west of the Andes — was far lower than previously thought.
