A Snapshot on the Buildup of the Stable Water Isotopic Signal in the Upper Snowpack at EastGRIP on the Greenland Ice Sheet
(Journal of Geophysical Research: Earth Surface, 2023-02-22)The stable water isotopic composition in firn and ice cores provides valuable information on past climatic conditions. Because of uneven accumulation and post‐depositional modifications on local spatial scales up to hundreds ... -
Quantitative critique of leaf‐based paleo‐CO2 proxies: Consequences for their reliability and applicability
(Geological Journal, 2020-03-18)A variety of proxies have been developed to reconstruct paleo‐CO2 from fossil leaves. These proxies rely on some combination of stomatal morphology, leaf δ13C, and leaf gas exchange. A common conceptual framework for ...
