The Land Beneath the Ice
"As soon as humans spied and later set foot on the remote Antarctic continent in the early nineteenth century, they became aware of its ice cover, and desired to learn about its extent, shape, thickness, and behavior. In this book, David Drewry-glaciologist and former Director of the Scott Polar Research Institute-recounts the science and history of a ground-breaking time in recent Antarctic geophysical exploration, in which scientists were finally able to "see" through the Antarctic ice sheet and take its measure. From the mid-1960s to the mid-1980s, scientists' ability to peer beneath the Antarctic ice sheet and map its thickness was revolutionized by the technology, techniques, and explor...
The Land Beneath the Ice
A wondrous story of scientific endeavor—probing the great ice sheets of Antarctica From the moment explorers set foot on the ice of Antarctica in the early nineteenth century, they desired to learn what lay beneath. David J. Drewry provides an insider’s account of the ambitious and often hazardous radar mapping expeditions that he and fellow glaciologists undertook during the height of the Cold War, when concerns about global climate change were first emerging and scientists were finally able to peer into the Antarctic ice and take its measure. In this panoramic book, Drewry charts the history and breakthrough science of radio-echo sounding, a revolutionary technique that has enabled res...

Glacial Sedimentary Processes and Products
Associating ice masses with the transport and deposition ofsediments has long formed a central theme in glaciology and glacialgeomorphology. The reason for this focus is clear, in that icemasses are responsible for much of the physical landscape whichcharacterizes the Earth's glaciated regions. This association alsoholds at a variety of scales, for example, from the grain-sizecharacteristics of small-scale moraines to the structuralarchitecture of large-scale, glacigenic sedimentary sequences inboth surface and subaqueous environments. This volume brings numerous state-of-the-art research contributionstogether, each relating to a different physical setting, spatialscale, process or investigative technique. The result is a diverseand interesting collection of papers by glaciologists, numericalmodellers and glacial geologists, which are all linked by the themeof investigating the relationships between the behaviour of icemasses and their resulting sedimentary sequences.
The Making of International Environmental Treaties
Gerry Nagtzaam contends that in recent decades neoliberal institutionalist scholarship on global environmental regimes has burgeoned, as has constructivist scholarship on the key role played by norms in international politics. In this innovative volume, the author sets these interest- and norm-based approaches against each other in order to test their ability to illustrate why and how different environmental norms take hold in some regimes and not others. The book explores why some global environmental treaties seek to preserve and protect some parts of nature from human utilization, some seek to conserve certain parts of nature for human development, whilst others allow the reckless exploit...
