Universities on Fire
Scientists agree that we are on the precipice of a global climate crisis. How will it transform colleges and universities? In 2019, intense fires in the San Francisco Bay Area closed universities and drove afflicted people to shelter at other campuses. At the same time, extraordinary fires ravaged eastern Australia. Several universities responded by promising material and research support to damaged businesses while also hosting refugees and emergency response teams in student residence halls. This was an echo of the devastation wreaked by Hurricane Katrina on Tulane University in 2005. In Universities on Fire, futurist Bryan Alexander explores higher education during an age of unfolding cli...
Arctic Ocean Sediments: Processes, Proxies, and Paleoenvironment
Although it is generally accepted that the Arctic Ocean is a very sensitive and important region for changes in the global climate, this region is the last major physiographic province of the earth whose short-and long-term geological history is much less known in comparison to other ocean regions. This lack of knowledge is mainly caused by the major technological/logistic problems in reaching this harsh, ice-covered region with normal research vessels and in retrieving long and undisturbed sediment cores. During the the last about 20 years, however, several international and multidisciplinary ship expeditions, including the first scientific drilling on Lomonosov Ridge in 2004, a break-throu...

On the Determination of Sediment Accumulation Rates
Sediment accumulation rates are an essential tool for the understanding of processes related to the deposition of organic and inorganic materials in marine and lacustrine environments. Sediment accumulation rates are not only a measure of the speed of deposition, but also represent a very useful tool for further paleoenvironmental reconstructions of climate history or biotic evolution as seen in the fossil record. The present volume provides an invaluable introduction to available strategies for the determination of the speed of sedimentation. It discusses the various methods and related problems, proposes new concepts and introduces selected applications in the form of case studies. Present...
