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.

Geoscience on Film: The view from outside Kathmandu

Doug Prose and Diane LaMacchia have produced documentaries showcasing Earth and the geosciences since 1992. At work on a project delving into the complex interplay of tectonics, natural hazards and humanity in the Himalayan region, LaMacchia and Prose traveled to Nepal and Bhutan in June to investigate recovery and resilience in the aftermath of the 2015 Gorkha earthquake. Prose wrote about their recent experiences while there, and filed the following series of posts upon returning home.

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.

Model targets better understanding of recurring Indian-Pacific storm systems

Scientists have known for decades that the Madden-Julian Oscillation (MJO) — a massive gathering of thunderstorms that forms intermittently over the Indian and western Pacific oceans — impacts regional and global weather. Predicting the impacts, however, has been more difficult because relatively little is known about the phenomenon, at least compared to El Niño and some other weather patterns. But in a new study, scientists have devised a mathematical model that clarifies how the MJO develops and progresses, which may pave the way for more accurate predictions of its effects.

Travels in Geology: Peninsular Greece: A gorgeous state of collapse

Peninsular Greece offers stunning scenery and extraordinary sights, including the temple at ancient Delphi, where geology helped produce the oracles' "visions"; Meteora's famed monastaries, perched atop pillars of conglomerate; and the precipitous heights of Mount Olympus.

Mineral Resource of the Month: Iron and Steel Slag

Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes. Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten crude iron or steel; the slag is then removed from the liquid metal.

Geologic Column: Thanksgiving's unsung hero

Thanksgiving as we know it in America today has only been celebrated since President Lincoln declared it a national holiday in 1863, thanks to the entreaties of Sarah Josepha Hale, an influential writer and editor.
