Download or read book Late Pleistocene Evolution of Glacial Lake Purcell written by Jared Lee Peters and published by . This book was released on 2012 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Quaternary history of the Channeled Scabland (CS) and its primary floodwater sources during marine isotope stage (MIS) 2 are well documented and understood. However, putative floodwaters from glacial lakes in British Columbia are poorly understood; these lakes may have supplied floodwaters to the CS in late MIS 2 during northward retreat of the Cordilleran Ice Sheet. This study combines geomorphology, sedimentology, stratigraphy, aerial photograph interpretation, ground penetrating radar, and geographic information science to reconstruct the paleogeography and evolution of glacial Lake Purcell in the Purcell Trench. Glacial Lake Purcell was a proglacial, ice-contact lake that was ~90 km long, up to 12 km wide, and ~360 m deep against its dam (Purcell Lobe). It contained >70 km3 of water just prior to drainage. It likely drained catastrophically (~47 km3 of water) down the Kootenay River valley into the Columbia River, though geomorphic evidence is equivocal.
Download or read book Paleolimnological Assessment of Environmental Changes Occurring on Pim Island Nunavut High Arctic Canada written by Alexandra ROuillard and published by . This book was released on 2010 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the documented sensitivity of polar environments, long-term monitoring data are especially sparse in these regions. Diatom-based paleolimnology has contributed significantly to understanding the response of Arctic lakes to climate change, but most studies have been conducted in regions with relatively high lakewater buffering capacity. As such, Pim Island (Nunavut, Canada) is a region of limnological interest because, due to the local geology, its surface waters are of relatively lower pH and previous research suggests that such softwater lakes may be especially responsive to climate fluctuations and therefore provide the best paleoclimate records. This thesis has two separate but related chapters, as well as an exploratory study included in appendix. First, a novel approach using visible-near-infrared spectroscopy (VNIRS) was used to infer lakewater dissolved organic carbon (DOC), from a 160-lake calibration set from the Canadian Arctic. Historically sound and similar trends were reconstructed when compared against a Canadian diatom-based DOC and Swedish VNIRS-based total organic carbon (TOC) model on Arctic Holocene sediment records. Second, a diatom and spectroscopically-based multi-proxy approach was utilized on Holocene sedimentary records from two lakes on Pim Island to assess long-term environmental change from this region. Benthic and epiphytic diatom taxa dominated the pre-19th century assemblages, although marked shifts in dominant species were recorded during the mid-Holocene. The mid-Holocene diatom assemblages underwent an abrupt ecological shift from alkaliphilous Fragilaria sensu lato to slightly acidophilous Achnanthes and Navicula. The post-19th century was characterized by an increase in the planktonic species (Cyclotella radiosa), indicating marked lakeice reductions. Third, the limnological properties and modern diatom assemblages of ponds and lakes surveyed from 1979 to 2009 on Pim Island were examined as part of an exploratory study. The ponds and lakes displayed typical characteristics observed in high Arctic lacustrine environments (i.e. oligotrophic, very dilute) but with overall relatively low alkalinity. Poorly-buffered sites had diatom assemblages that were distinct from well-buffered lakes elsewhere in the High Arctic. Our findings contribute to an improved understanding of the interactions between local environments and limnological changes, and also provide insight on the biological responses of lakes to Holocene environmental change and allow us to compare responses to those in more alkaline sites.

Download or read book Environmental Chemistry and Toxicology of Mercury written by Guangliang Liu and published by John Wiley & Sons. This book was released on 2011-11-07 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the fundamentals, recent developments, and future research needs for critical mercury transformation and transport processes, as well as the experimental methods that have been employed in recent studies. The coverage discusses the environmental behavior and toxicological effects of mercury on organisms, including humans, and provides case studies at the end of each chapter. Bringing together information normally spread across several books, this text is unique in covering the entire mercury cycle and providing a baseline for what is known and what uncertainties remain in respect to mercury cycling.

Book excerpt: Now in its second edition, Pollution of Lakes and Rivers provides essential insights into present-day water quality problems from an international perspective.

It is likely to prove useful as an introduction to the general area, a reference source and for teaching purposes." (The Holocene, November 2008) "If you thought that paleolimnology was just mud, pollen, and diatoms then you will likely be both struck by the complexity of this field of research and grateful that John Smol, FRSC, has described it so clearly and broadly. Simply put, the second edition is an excellent book." ( Journal of Phycology, 2008) “This is a useful text. It provides a good level of detail so that the beginner in this area can appreciate what palaeolimnology can (and cannot) achieve. It goes beyond the simple introduction to provide a detailed understanding of how techniques can be applied ... This is a different take on the usual pollution text and would be of great use to those wishing to understand more from sedimentary records.” Taken from the British Ecological Society’s Teaching Ecology website "John Smol has extensive experience in this field of paleoenvironmental research which he combines well with his excellent written communication skills to produce a text that is easy to read but also thought provoking." (Quaternary Science Reviews, 2009) “The breadth of coverage in this text is impressive.” (Lake and Reservoir Management, 2009) “If I could speak with fluidity and clarity in my lectures as consistently as John Smol writes my students would be very grateful.” (Journal of Paleolimnology, 2009)
