Mapping High‐TDS Groundwater Near Impoundments Using Ground and Waterborne Towed Electromagnetics

Groundwater, EarlyView.
Abstract Long‐term monitoring at landfills and impoundments containing coal combustion products (CCPs) or other industrial wastes is essential for detecting possible leachate releases to groundwater and mapping contamination plumes. This study evaluates a novel, non‐invasive geophysical approach—towed time‐domain electromagnetic (TEM) surveys—for non ...

Consumer Mobility, Offline and Online Regional Trade: Evidence From High‐Frequency Transaction Data

International Economic Review, EarlyView.
ABSTRACT The shift from offline to online purchasing is reshaping trade patterns: a weaker effect of distance has been observed in digital transactions. This study analyzes these dynamics at an unprecedented scale and granularity, using interregional gravity models estimated from billions of geolocated French card transactions.
