Seasonal variability in Northern Hemisphere atmospheric circulation during the Medieval Climate Anomaly and the Little Ice Age
Autor: Hans Linderson, Christophe Sturm, Brandi W. Newton, Dan Hammarlund, Natalie A. St. Amour, Jesper Sjolte, Joscelyn N.-L. Bailey, Thomas W. D. Edwards, Anders Nilsson
Publikováno v: Quaternary Science Reviews. 165:102-110
Here we report new reconstructions of winter temperature and summer moisture during the past millennium in southeastern Sweden, based on stable-isotope data from a composite tree-ring sequence, that further enhances our knowledge and understanding of

Late Holocene expansion of Siberian dwarf pine (Pinus pumila) in Kamchatka in response to increased snow cover as inferred from lacustrine oxygen-isotope records
Autor: Andrei Andreev, Natalie A. St. Amour, Thomas W. D. Edwards, Andrea Klimaschewski, Dan Hammarlund, Lena Barnekow, Nadia Solovieva, Elinor Andrén, Angela Self
Publikováno v: Global and Planetary Change. 134:91-100
Holocene records of cellulose-inferred lake-water delta O-8 were produced from two lake-sediment sequences obtained in central and northern Kamchatka, Russian Far East. The sediment records share similar fluctuations in delta O-8 during the interval

New insights into Holocene atmospheric circulation dynamics in central Scandinavia inferred from oxygen-isotope records of lake-sediment cellulose
Autor: Natalie A. St. Amour, Dan Hammarlund, Brent B. Wolfe, Thomas W. D. Edwards
Publikováno v: Boreas. 39:770-782
Cellulose-inferred lakewater oxygen-isotope records have been obtained from two hydrologically open basins (Lake Spaime and Lake Svartkalstjarn), located on a west east transect across central Sweden, to investigate changes in atmospheric circulation

Boreal forest dynamics in north-eastern Sweden during the last 10,000 years based on pollen analysis
Autor: Natalie A. St. Amour, Petra Bragée, Lena Barnekow, Dan Hammarlund
Publikováno v: Vegetation History and Archaeobotany. 17:687-700
A pollen record obtained from a 2.2-m sediment succession deposited in a small lake in the province of Vasterbotten, north-eastern Sweden, reveals the presence of continuous forest cover since 8,500 calendar years before present (cal B.P.). Forest wi

Progress in isotope paleohydrology using lake sediment cellulose
Autor: Yi Yi, Natalie A. St. Amour, Matthew D. Falcone, Bronwyn E. Brock, Thomas W. D. Edwards, Ken P. Clogg-Wright, Cherie L. Mongeon, Brent B. Wolfe, William A Mark
Publikováno v: Journal of Paleolimnology. 37:221-231
Recent advances in sample preparation techniques and mass spectrometry have fostered more routine oxygen isotope analysis of aquatic cellulose in lake sediment cores, a proxy for lake water oxygen isotope history. These methodological developments ha

Isotopic time-series partitioning of streamflow components in wetland-dominated catchments, lower Liard River basin, Northwest Territories, Canada
Autor: Terry D. Prowse, Natalie A. St. Amour, John J. Gibson, Alain Pietroniro, Thomas W. D. Edwards
Publikováno v: Hydrological Processes. 19:3357-3381
The distribution of stable water isotopes provides valuable insight into runoff generation processes in subarctic wetland regions of the Mackenzie River basin, a major freshwater contributor to the Arctic Ocean and the focus of intensive hydrological
