Lead and Antimony in Basal Ice From Col du Dome (French Alps) Dated With Radiocarbon: A Record of Pollution During Antiquity
Susanne Preunkert,Joseph R. McConnell,Helene Hoffmann,Helene Hoffmann,Michel Legrand,Andrew Wilson,Sabine Eckhardt,Andreas Stohl,Nathan Chellman,Monica M. Arienzo,Ronny Friedrich +10 more
TL;DR: Lead and antimony measurements in basal ice from the Col du Dome glacier document heavy metal pollution in western Europe associated with emissions from mining and smelting operations during European antiquity.
Temperature and mineral dust variability recorded in two low-accumulation Alpine ice cores over the last millennium
Pascal Bohleber,Pascal Bohleber,Pascal Bohleber,Tobias Erhardt,Tobias Erhardt,Nicole E. Spaulding,Helene Hoffmann,Hubertus Fischer,Hubertus Fischer,Paul Andrew Mayewski +9 more
TL;DR: In this paper, the authors explore the time series of stable water isotopes and the mineral dust proxies Ca 2+ and insoluble particles at the Colle Gnifetti glacier in the European Alps.
Alpine ice-core evidence for the transformation of the European monetary system, AD 640–670

TL;DR: In this article, the authors integrated ice-core data from the Colle Gnifetti drill site in the Swiss Alps, geoarchaeological records and numismatic and historical data to demonstrate that significant new silver mining facilitated the change from gold to silver coinage, and dates the introduction of such coinage to c. AD 660.

A New Sample Preparation System for Micro-14C Dating of Glacier Ice with a First Application to a High Alpine Ice Core from Colle Gnifetti (Switzerland)
Helene Hoffmann,Susanne Preunkert,Michel Legrand,David Leinfelder,Pascal Bohleber,Ronny Friedrich,Dietmar Wagenbach +6 more
TL;DR: The authorsILOX The authors is a sample preparation system for dating of glacier ice samples via radiocarbon (14C) dating of the microscopic particulate organic carbon (POC) fraction incorporated in the ice matrix.
