"Kharkovchanka" - The Colossal Soviet Antarctic Cruisers
> “The Kharkovchanka” - Russia’s Colossal Antarctic Cruisers which have been continuously operating in some of the most extreme environments on Earth for over 50 years. Produced in Kharkiv, Ukrainian Soviet Socialistic Republic and originally operated by USSR, the ’Харьковчанка’ (literally ‘Kharkiv Women’), these amazing Snow Cruisers were built in the late 1950s and featured everything a polar explorer could need in the field. In their half-century mission, they have crossed thousands of miles on Antarctic Ice, visited the South Pole, the pole of inaccessibility as well the dozens of outposts and research stations on the continent.

The U.S. Is Getting Shorter, as Mapmakers Race to Keep Up
> Scientists are hard at work recalibrating where and how the nation physically sits on the planet. It’s not shrinkage — it’s “height modernization.”
> The grand recalibration, called “height modernization,” is part of a broader effort within the National Oceanic and Atmospheric Administration, or NOAA, to establish more accurately where and how the United States physically sits on the planet. This new National Spatial Reference System, encompassing height, latitude, longitude and time, is expected to be rolled out in late 2022 or 2023, Ms. Blackwell said. It will replace reference systems from the 1980s that are slightly askew, having been derived from calculations that were done before the advent of supercomputers or global navigation satellite systems such as GPS.
Arch Rivals Quarrel Over Quirky Geological Formations

Walker Lane Redux
> To make a story short, a handful of geologists have speculated, at least since the late 1980s, that the San Andreas Fault could actually be dying out over time—that the San Andreas is jammed up in a place called the “Big Bend,” near the town of Frazier Park, and that it is thus losing its capacity for large earthquakes.
> As a result, all of that unreleased seismic strain has to go somewhere, and there is growing evidence—paleoseismic data, LiDAR surveys, GPS geodesy—that the pent-up strain has been migrating deep inland, looking for a new place to break.
> That new route—bypassing the San Andreas Fault altogether—is the Walker Lane (and its southern continuation into the Mojave Desert, known as the Eastern California Shear Zone).
> I was thus instantly fascinated several years ago when I read about something called the Walker Lane, a huge region of land stretching roughly the entire length of the Eastern Sierra, out near the California/Nevada border, which some geologists now believe is the actual future edge of the North American continent—not the San Andreas. It is an “incipient” continental margin, in the language of structural geology.
Drift of the North Pole forces early magnetic map update
> As the magnetic field’s quirks are dynamic, the model has to be updated, which is done on a five-year schedule. The rate of the North Pole’s motion, however, has been fast enough that the agencies who produce the model aren’t comfortable with waiting for the current model expiration at the end of 2019.
The Anthropocene Project
> The Anthropocene Project is a multidisciplinary body of work from world-renowned collaborators Nicholas de Pencier, Edward Burtynsky and Jennifer Baichwal. Combining art, film, virtual reality, augmented reality, and scientific research, the project investigates human influence on the state, dynamic and future of the Earth.
