TL;DR: In this paper, the authors examined why a conventional, or sea surface temperature, interpretation of the Greenland GRIP excess record seems inconsistent with inferred site and source temperature changes and assessed its geographic significance through a comparison with existing Dye 3 and North GRIP data.
Journal ArticleDOI
Reconstruction of past precipitation δ18O using tree-ring cellulose δ18O and δ13C: A calibration study near Lac d'Annecy, France
Pierre-Alain Danis,Valérie Masson-Delmotte,Michel Stievenard,M. T. Guillemin,Valérie Daux,Ph. Naveau,U. von Grafenstein +6 more
TL;DR: In this article, the stable isotope composition of the latewood cellulose was analyzed in terms of oxygen and carbon isotopic composition for the period 1971-2001 and compared to the nearby monthly meteorological (temperature, relative humidity) and isotopic compositions of precipitation records.
Journal ArticleDOI
Intense storm activity during the Little Ice Age on the French Mediterranean coast.
Laurent Dezileau,Pierre Sabatier,Pierre Sabatier,Philippe Blanchemanche,Baptiste Joly,Didier Swingedouw,Christophe Cassou,Jérôme Castaings,Philippe Martinez,U. von Grafenstein +9 more
TL;DR: In this article, the authors present a record of these extreme climatic events that have occurred in the French Mediterrannean coast over the past 1500 years, based on the analysis of sediment cores from Gulf of Aigues-Mortes lagoons.
Journal ArticleDOI
Extreme sea events during the last millennium in the northeast of Morocco
TL;DR: In this paper, a multi-proxy approach was applied combining sedimentological and geochemical data to identify extreme sea events, and three paleo events were identified; all of them are concentrated over the last 500 years, and the most recent event corresponds to the 1889 storm.
Journal ArticleDOI
Sensitivity of deep lake temperature to past and future climatic changes: A modeling study for Lac d'Annecy, France, and Ammersee, Germany
TL;DR: In this paper, a one-dimensional eddy diffusion thermal lake model including a lake ice model and refined it by including a seasonal light extinction model was tested for two different sites, Lac d'Annecy and Ammersee.
