  • What’s new in exploration


    Nina M. Rach

    Earth history is recorded at many scales. Trees accumulate decades, centuries, even millennia of layered rings reflecting climate variations of time past. Sediments are laid down over eras and epochs, sometimes carried to the deepest parts of the ocean and immediately buried. Paleontologists have organized plant and animal fossils to date many formations. Macrostratigraphy is an emerging technique used by geologists to tie together data from disparate regions. It’s in the limelight now, with a recent letter published in Nature, and an upcoming paper in the GSA Bulletin. Both use data synthesized within the Macrostrat project at the University of Wisconsin-Madison.
