First global topographic map of Mercury released

Mercury’s surface is arid, gray and scarred by craters over much of its landscape. Given its close proximity to the sun, a manned trip to Mercury is out of the question — but now you can explore Mercury’s pockmarked surface in its entirety with the first global topographic map of the planet.

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.

Comment: What's a map worth? The big cost and bigger benefit of three-dimensional elevation data

The 3-D Elevation Program is a collaborative effort to share the costs of collecting three-dimensional elevation data over the entire U.S. over an eight-year period. The end goal is a fully three-dimensional elevation map of the entire U.S. and its territories.

A new gravity map of Earth

Gravity differs from place to place around Earth because of the uneven distribution of mass across and within the planet. Scientists can study the variation in gravitational pull by measuring the gravity field at different places on the surface of the planet. In a new study published in Scientific Reports, gravity field data collected over the entire planet between 2009 and 2013 by the European Space Agency’s Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) satellite has been mapped, revealing many of Earth’s internal features, such as magmatic plumes welling up toward the surface.

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.

Comment: Assessing the threat from massive rock slope failures in the Norwegian fjordlands

Records dating back to the Vikings describe large rock avalanches into Norwegian fjords that set off lethal displacement waves. Today, increased development and tourism are exacerbating the risk.

First all-digital geologic map of Alaska released

When it comes to natural beauty, Alaska’s rugged, massive landscape is an embarrassment of riches, with towering mountains and lush forests, countless islands and a seemingly endless coastline. Below the surface, it features a wealth of interesting geology and abundant resources. Now, policymakers, land managers, scientists and the public can all explore Alaska a little more deeply with the recent release of the first-ever fully digital geologic map of the entire state.

Down to Earth With: Tectonicist Eldridge Moores

When Eldridge Moores was 10 years old, his family lived in Crown King, Ariz., a tiny, remote mining settlement high in the rugged Yavapai Mountains northwest of Phoenix. Money was tight and his family rarely traveled, so Moores vividly remembers a holiday road trip to visit his father’s relatives near San Francisco. The Bay Area left a deep impression on Moores, and, at the end of the journey, upon reaching the first of four switchbacks on the narrow dirt track that led up to Crown King, Moores vehemently pronounced that he would do everything he could to get out of there.

Golden Gate ghost ships rediscovered

Just beyond San Francisco’s Golden Gate Bridge is a shipwreck graveyard where as many as 300 vessels lie in silty underwater repose. A team of NOAA researchers conducting a two-year study to identify and map the long-forgotten ships in the Gulf of the Farallones National Marine Sanctuary and the adjacent Golden Gate National Recreation Area has announced the discovery of three wrecks: the 1863 wreck of the clipper ship Noonday, the 1910 shipwreck SS Selja and an unidentified early steam tugboat wreck tagged the “mystery wreck” — all now obscured by mud and silt on the ocean floor.
