Reading Landscape: Mid-Century Modernism And The Landscape Idea, Jeffrey David Blankenship
Open Access Dissertations
This dissertation traces the recovery of the landscape idea during the middle decades of the 20th century by a group of public intellectuals, scholars and designers responding to the everyday realities of the modern American built environment. That recovery served as a corrective to modernism's construction of landscape as either abstract utopian space or retrogressive historical tableau. The primary catalyst for this renewed interest in landscape as a representation of human cultures and their complex relationship with the natural world was the essayist and critic John Brinckerhoff Jackson (1909-1996) and his magazine Landscape. During the years of Jackson's editorship (1951-1968), …
Lacustrine Records Of Holocene Climate And Environmental Change From The Lofoten Islands, Norway, Nicholas L. Balascio
Lacustrine Records Of Holocene Climate And Environmental Change From The Lofoten Islands, Norway, Nicholas L. Balascio
Open Access Dissertations
Lakes sediments from the Lofoten Islands, Norway, can be used to generate well resolved records of past climate and environmental change. This dissertation presents three lacustrine paleoenvironmental reconstructions that show evidence for Holocene climate changes associated with North Atlantic climate dynamics and relative sea-level variations driven by glacio-isostatic adjustment. This study also uses distal tephra deposits (cryptotephra) from Icelandic volcanic eruptions to improve the chronologies of these reconstructions and explores new approaches to crypto-tephrochronology. Past and present conditions at Vikjordvatnet, Fiskebølvatnet, and Heimerdalsvatnet were studied during four field seasons conducted from 2007-2010. Initially, each lake was characterized by measuring water …
