This book is a comprehensive overview of the ever-captivating field of glaciation from the perspective of glacial landsystems. This approach models the many processes, forms and interactions that can be found in glaciated landscapes throughout the world. Landsystems models allow the glacial geologist and geomorphologist to evaluate these landscapes in relation to the dynamics of glaciation and to climate and geology. Glacial Landsystems brings together the expertise of an international range of specialists to provide an up-to-date summary of landsystems relevant to both modern and ancient glacier systems and also in the reconstruction and interpretation of former glacial environments. The models are applicable at all scales from ice sheets to small valley glaciers. This book is an essential reference for anyone embarking upon research or engineering surveys in glaciated basins and provides a wide-ranging handbook of glacial landsystem types for students of glaciation.

European Glacial Landscapes: The Holocene presents the current state of knowledge on glacial landscapes of Europe and nearby areas over the Holocene to deduce the influence of atmospheric and oceanic currents and the insolation forcing variability and volcanic activity on Holocene paleoclimates, the existence of asynchronies in the timing of occurrence of glacier expansion and shrinkage during the Holocene, time lags between the identification of oceanic and atmospheric changes and those occurring in glacial extension during the Holocene, the role of Holocene glaciers on the climate of Europe, and on sea level variability, and the delimitation of landscapes that need special protection. Students, academics and researchers in Geography, Geology, Environmental Sciences, Physics and Earth Science departments will find this book provides novel findings of all the major European Regions in a single publication, with updated information about Holocene glacial geomorphology and paleo-climatology and clear figures that model the landscapes covered. Provides a synthesis and summary of glacial processes in Europe over the Holocene period Features research from experts in palaeo-climatology, palaeo-oceanography and palaeo-glaciology Includes access to a companion website with an interactive map, photos of glacial features, and geospatial data related to European Glacial Landscapes

3 new biota and extinction of others, and extensive soil erosion reaching almost catastrophic proportions have led to desertification of many upland areas and abandonment by local populations. The role of climatic change as opposed to deforestation and sheep grazing in creating these new environments has proved a further issue of great controversy. While our understanding of historic environmental changes remains inadequate, our knowledge of processes that are modifying the present-day landscape is also sparse and selective. Little is known of active periglacial processes, slope instabilities, and rates of soil erosion by slope wash and aeolian transport. Coastal processes of erosion and beach formation have been studied only locally. Most of our information on recent or active processes comprises records of glacier fluctuations, volcanic eruptions and jOkulhlaup events, but sti11little is known of the mechanisms and processes of landscape change effected by these events. This volume of papers, based on a conference sponsored by the Quaternary Research Association and the Geologists Association and held at the University of Aberdeen in April 1989, addresses many of these crucial uncertainties regarding environmental changes in Iceland from the Lateglacial onwards. The papers make a major contribution to dispelling many earlier uncertainties and clarifying areas of controversy. Many of the papers challenge traditional and poorly supported ideas, replacing them with hypotheses based on new data and new insights derived from the expansion of wider scientific expertise and theory. The volume focuses on three major areas of research in particular.

Provides the first comprehensive review of the current state of the science on tills It is critical that glacial scientists continue to refine their interpretations of ancient archives of subglacial processes, specifically those represented by tills and associated deposits, as they form the most widespread and accessible record of processes at the ice-bed interface. Unfortunately, despite a long history of investigation and a lexicon of process-based nomenclature, glacial sedimentologists have yet to reach a consensus on diagnostic criteria for identifying till genesis in the geological record. What should be called till? Based on the author’s extensive field research, as well as the latest literature on the subject, this book attempts to provide a definitive answer to that question. It critically reviews the global till literature and experimental and laboratory-based assessments of subglacial processes, as well as the theoretical constructs that have emerged from process sedimentology over the past century. Drawing on a wide range of knowledge bases, David Evans develops a more precise, contemporary till nomenclature and new investigatory strategies for understanding a critical aspect of glacial process sedimentology. Provides an in-depth discussion of subglacial sedimentary processes, with an emphasis on the origins of till matrix and terminal grade and the latest observations on till evolution Describes contemporary laboratory and modelling experiments on till evolution and techniques for measuring strain signatures in glacial deposits Develops an updated till nomenclature based on an array of knowledge bases and describes new strategies for field description and analysis of glacial diamictons Written by an internationally recognised expert in the field, this book represents an important step forward in the modern understanding of glacial process sedimentology. As such, Till: A Glacial Process Sedimentology is an indispensable resource for advanced undergraduates and researchers in sedimentology, glacier science and related areas.

Abstract: While iceberg calving makes up a substantial portion of mass loss for marine-terminating glaciers, these dynamics remain poorly represented in predictions of sea-level rise and large-scale climate models, requiring more robust observational datasets. Breiðamerkurjökull glacier functions as a uniquely controlled field setting for obtaining a wide variety of environmental and geodetic measurements in conjunction with monitoring calving flux, making it possible to more carefully constrain the sometimes-contradictory relationships between calving and environmental conditions observed in previous studies. A time-lapse camera and water level logger were placed roughly 1 km from the glacier ice front to monitor ice loss and iceberg-generated tsunamis from April to September 2011. This record was used to estimate the volume of ice lost by calving during this period and obtain calving rates on hourly, daily, and weekly timescales. Weather, tide, and contemporaneous records of the temperature-salinity structure of the lagoon were used to examine relationships between these factors and calving. Calving was shown to be more common during the falling tide in both spring and fall.
