Data-driven discovery reveals Earth's missing minerals

New discoveries in mineralogy, one of the oldest human endeavors, are arising from a new sort of mining—data mining. Mineralogists are applying statistical models and data science techniques to reveal previously unseen patterns and clues hidden in mineralogical databases, and to find undiscovered minerals.

Recovery of 1960s sea-ice satellite images wins dark data contest

Scientists from the National Snow and Ice Data Center (NSIDC) and NASA who resurrected 50-year-old satellite images of Arctic and Antarctic sea ice from dusty 35-millimeter film reels took home first prize in an international geoscience data rescue contest sponsored by publisher Elsevier and the Integrated Earth Data Applications project at Columbia University’s Lamont-Doherty Earth Observatory.

Geologic Column: Data security: freezers, floppies and flash drives

In the olden days, many of us protected our field notes, lab records and draft manuscripts by making multiple photocopies, storing them in different places, and perhaps keeping one in the freezer in case of fire. Today, much of our data is collected and stored electronically. What strategies do we use now to protect against catastropic loss?

Digitizing Earth: Developing a cyberinfrastructure for the geosciences

That geoscientists are notorious hoarders should come as no surprise. After all, geoscientists collect and study nothing less than Earth itself. Over the last four decades, massive amounts of digital data have begun streaming in from a growing number of satellites and sensors unceasingly monitoring the earth, atmosphere and oceans. Geoscientists are awash in data and, at the same time, have access to ever-increasing computing power. Together, these advances have precipitated fundamental changes in the way earth science is done, leading to the proliferation of computer-based data visualization and modeling — especially 3-D and 4-D modeling.

Rescuing data from the dark

Along with the proliferation of techniques and technologies to deal with Big Data — the large volumes of data coming in from global sensors and satellites that can require supercomputers to crunch — geoscientists are also addressing the collection and integration of what could be termed small (or mainstream) data.
