Tracking Environmental Change Using Lake Sediments
TLDR
This book brings together a wide array of numerical and statistical techniques currently available for use in palaeolimnology and other branches of palaeoecology.Abstract:
Numerical and statistical methods have rapidly become part of a palaeolimnologist’s tool-kit. They are used to explore and summarise complex data, reconstruct past environmental variables from fossil assemblages, and test competing hypotheses about the causes of observed changes in lake biota through history. This book brings together a wide array of numerical and statistical techniques currently available for use in palaeolimnology and other branches of palaeoecology.read more

TL;DR: Fifty-five paleolimnological records from lakes in the circumpolar Arctic reveal widespread species changes and ecological reorganizations in algae and invertebrate communities since approximately anno Domini 1850, indicating that the opportunity to study arctic ecosystems unaffected by human influences may have disappeared.

Pollution of Lakes and Rivers: A Paleoenvironmental Perspective
TL;DR: The second edition of the Rosetta Stone has been published by as discussed by the authors, which is used to calibrate indicators to environmental variables using surface-sediment training sets, such as ozone depletion, acid rain, and climatic warming.

TL;DR: This gradual rather than abrupt termination of the African Humid Period in the eastern Sahara suggests a relatively weak biogeophysical feedback on climate.

The Avaatech XRF Core Scanner: technical description and applications to NE Atlantic sediments
T. O. Richter,Sjerry van der Gaast,Bob Koster,Aad Vaars,Rineke Gieles,Henko de Stigter,Henk de Haas,Tjeerd C.E. van Weering +7 more
TL;DR: The Avaatech XRF Core Scanner as discussed by the authors provides high-resolution X-ray fluorescence (XRF) records of chemical composition on split sediment cores, which can be used for preliminary stratigraphic interpretations (glacial-interglacial cycles), provenance studies of the terrigenous sediment fraction, lithological characterization, early diagenetic processes and distinction between carbonate phases.

A review of molecular organic proxies for examining modern and ancient lacustrine environments
TL;DR: In this article, the use of a number of commonly utilized organic geochemical and isotopic proxies and their potential for environmental reconstruction in Quaternary lacustrine deposits is discussed.
