Current practices in building and reporting age-depth models
Terri Lacourse,Konrad Gajewski +1 more
TL;DR: In this article, the authors present a case study of building age-depth models for a lake sediment core that has both 14C ages and an independent varve chronology, and show that choosing the best model is not a simple task, and that model accuracy is ultimately controlled by differences between 14c ages and true age that likely occur in many late Quaternary records.
The climate of North America during the past 2,000 years reconstructed from pollen data
TL;DR: In this article, the temperature of the warmest month was reconstructed for the past 2000 years using 748 pollen sites from the North American Pollen Database using the Modern Analog Technique.

The long-term impacts of climate and fire on catchment processes and aquatic ecosystem response in Tasmania, Australia
Kristen K. Beck,Kristen K. Beck,Michael-Shawn Fletcher,Patricia Gadd,Henk Heijnis,Krystyna M. Saunders,Atun Zawadzki +6 more
TL;DR: A 9200 year Holocene record of sedimentary Carbon/Nitrogen, x-ray fluorescence, charcoal, pollen, and diatoms preserved within a freshwater lake in Tasmania was used to understand the influences of climate variability and fire on aquatic ecosystem response.
Journal ArticleDOI
Flood variability in the common era: a synthesis of sedimentary records from Europe and North America
TL;DR: In this paper, the authors show that heavy precipitation events increased over the last century in response to higher atmospheric temperature and associated increases in water vapor content, but little evidence shows that increased he...

Journal ArticleDOI
Varves in lake sediments – a review
TL;DR: In this article, a multidisciplinary approach is proposed to establish a varve chronology, which can be applied to precisely date events like volcanic ash layers, earthquakes or human impact, as well as short and long-term climate (temperature, precipitation, wind, hydroclimatic conditions or flooding) and environmental changes (eutrophication, pollution).
Journal ArticleDOI
Chemical and biological trends during lake evolution in recently deglaciated terrain.
TL;DR: The results demonstrate a tight hydrologic coupling between terrestrial and aquatic environments during the colonization of newly deglaciated landscapes, and provide a conceptual basis for mechanisms of primary succession in boreal lake ecosystems.
Journal ArticleDOI
Lake diatom responses to warming: reviewing the evidence
TL;DR: This article examined the role that climate-mediated alterations in inter-related lake processes have played on diatom community composition, dynamics and size structure, with particular attention to the recent success of planktonic diatom species relative to heavier tychoplanktonic and small benthic diatoms.

A severe centennial-scale drought in midcontinental North America 4200 years ago and apparent global linkages
Robert K. Booth,Stephen T. Jackson,Steven L. Forman,John E. Kutzbach,E. A. Bettis,Joseph Kreigs,David K. Wright +6 more
TL;DR: In this paper, the authors present evidence from a variety of physical and biological proxies for a severe drought that affected the mid-continent of North America between 4.1 and 4.3 ka.

Fisheries productivity in the northeastern Pacific Ocean over the past 2,200 years
TL;DR: Reconstruction of ∼2,200-year records of sockeye salmon abundance from sediment cores obtained from salmon nursery lakes on Kodiak island, Alaska demonstrates the strong role of climatic forcing in regulating northeastern Pacific fish stocks.
