Boreas, EarlyView.This study investigates the ecology of the extinct European Hippopotamus from the late Early–Middle Pleistocene (c. 900–400 ka) sequence of the Megalopolis Basin, a glacial microrefugium for temperate taxa in southern Greece. Using stable carbon (δ13C) and oxygen (δ18O) isotope analyses and microwear analyses of Hippopotamus dental elements, we ...

Appraisal of Six Natural Mica Reference Materials for In Situ Rb‐Sr Geochronology
Geostandards and Geoanalytical Research, EarlyView.Key Points Evaluated six natural mica reference materials for in situ LA‐ICP‐MS/MS Rb‐Sr geochronology using geochemical, microstructural and isotopic characterisation. Identified robust primary reference materials: Mount Dromedary biotite (99.37 Ma) and Mica‐Fe biotite (307.75 Ma). La Posta biotite and Högsbo muscovite are suitable secondary reference

Radiometric Source Traceability for the Ground Calibration of OLI 2 [PDF]
, 2019 The Operational Land Imager 2 (OLI-2) has undergone absolute spectral radiance calibration at Ball Aerospace. A 40” integrating sphere source (DSS) is used as the NIST-traceable artifact in the OLI-2 ground calibration.

Russia's Wartime Economy: Measuring Regional Inequalities From Outer Space
Journal of Regional Science, EarlyView.ABSTRACT We study Russia's February 2022 full‐scale invasion of Ukraine as a natural experiment to determine how sudden disruptions to international market access reshape sub‐national economic inequalities. Using remotely‐sensed nighttime lights as a proxy for economic activity, we estimate the economic effects of the war at the national and regional ...

Europe, We Have a Problem! Local Economic Winners and Losers of Border Closures
Journal of Regional Science, EarlyView.ABSTRACT In response to COVID‐19, Schengen countries temporarily reintroduced internal border controls, disrupting cross‐border integration. Using this policy change as a natural experiment and monthly nighttime lights data, we estimate the short‐run effects on European municipalities.
