Book Description
The Discovery of the calcareous Ioffe Drift in the SW Atlantic in 2010 opens new perspectives in the contourite theory. Although demonstrating similar behavior relative to bottom water dynamics, rather rare and poorly studied calcareous contourites differ from their terrigenous analogs in origin, grain-size distribution, chemical and mineral composition of sedimentary particles. The detailed multidisciplinary study of the Ioffe Drift produces new knowledge on biogenic contourites deposited in pelagic realm, in conditions of low biological productivity and terrigenous material supply, under the influence of the Antarctic Bottom Water flow from the Vema Channel. The major intervals of prevailing erosion are inferred on the drift from 2.51/2.59 to 1.9 Ma and from 1.6 to 0.81 Ma thus indicating strong paleoceanographic changes most likely associated with the reorganization of deep-sea circulation and increased bottom water production in the Southern Ocean during the Early Pleistocene and, in particular, around the Mid-Pleistocene Transition.

Book Description
A Christianity Today 2015 Book Award Winner Is your organization in danger of Mission Drift? Without careful attention, faith-based organizations drift from their founding mission. It's that simple. It will happen. Slowly, silently, and with little fanfare, organizations routinely drift from their purpose, and many never return to their original intent. Harvard and the YMCA are among those that no longer embrace the Christian principles on which they were founded. But they didn't drift off course overnight. Drift often happens in small and subtle ways. Left unchecked, it eventually becomes significant. Yet Mission Drift is not inevitable. Organizations such as Compassion International and InterVarsity have exhibited intentional, long-term commitment to Christ. Why do so many organizations--including churches--wander from their mission, while others remain Mission True? Can drift be prevented? In Mission Drift, HOPE International executives Peter Greer and Chris Horst tackle these questions. They show how to determine whether your organization is in danger of drift, and they share the results of their research into Mission True and Mission Untrue organizations. Even if your organization is Mission True now, it's wise to look for ways to inoculate yourself against drift. You'll discover what you can do to prevent drift or get back on track and how to protect what matters most. "No organization is exempt from the danger of drifting away from its original mission. In Mission Drift, Peter and Chris provide solid guidance for remaining laser-focused on core values--from the board level to daily organizational culture. This book is a timely message for any organization working hard to remain Mission True." --Wess Stafford, president-emeritus, Compassion International "Peter Greer and Chris Horst have identified one of the deepest challenges any leader faces: how to ensure that an organization stays true to its mission, especially when that mission becomes countercultural." --Andy Crouch, executive editor, Christianity Today "Essential reading for twenty-first-century believers if we are to gain new vision, unity, and strength. Mission Drift is spine straightening, mind clearing, and courage inspiring. This book is true-north wisdom for leaders--and a gift of hope for the world God loves." --Kelly Monroe Kullberg, founder, The Veritas Forum and author, Finding God Beyond Harvard "Many of us in leadership have learned--often painfully--that our mission needs to be built into every aspect of our organization, from leadership to receptionist, from hiring to implementation. We can't afford not to follow the lessons in this valuable book." --Richard Stearns, president, World Vision U.S. and author, The Hole in Our Gospel "Keeping an eternal perspective is essential in our work. Mission Drift gives a clear message inspiring and challenging us to intentionally keep Christ at the center of all efforts." --David Green, founder and CEO, Hobby Lobby Stores, Inc. "Written with clarity, boldness, and urgency, the authors provide insight into and examples of the causes and solutions to drift using the stories of real organizations...A must-read! Recommend this book to every business and church leader."--CBA Retailers+Resources "This book is a must-read for leaders, easy to read, practical, engaging and inspirational. The principals outlined not only apply to major corporations, but also to any organization, church and even to one's own personal life. Mission Drift . . . will be well worth the effort and time, and you will find yourself wanting to begin implementing what you've learned to safeguard your organization from drifting away from its mission."--Foursquare.org

Book Description
The issue of global warming and climate change is of continuous concern. Since the 1970s, it bas been shown that the pack-ice around the Arctic Ocean is thinning, the margin of permafrost is moving north and the vegetation in the high northern parts of the world is changing (the 'greening' of the Arctic). But are these changes the result of human activity or simply regular variations of the Earth's climate system? Over thousands of years, a continuous archive of iceberg and sea ice drift bas formed in the deep-sea sediments, revealing the place of the ice's origin and allowing a reconstruction of the surface currents and the climate of the past. However, the drift of floating ice from one place to another is not just a passive record of past ocean circulation. It actively influences and changes the surface ocean circulation, thus having a profound effect on climate change. Ice Drift, Ocean Circulation and Climate Change is the first book to focus on the interactions between ice, the ocean and the atmosphere and to describe how these three components of the climate system influence each other. It makes clear the positive contribution of paleoclimatology and paleoceanography and should be read by anyone concerned with global warming and climate change.

Book Description
"The book provides an excellent historical summary of the debates over continental drift theory in this century." —Contemporary Sociology "This is a useful discussion of the way that science works. The book will be of value to philosophers of science . . . " —Choice " . . . will find an important place in university and department libraries, and will interest afficionados of the factual and intellectual history of the earth sciences." —Terra Nova " . . . an excellent core analysis . . . " —The Times Higher Education Supplement " . . . an ambitious and important contribution to the new sociology of science." —American Journal of Sociology " . . . Stewart's book is a noble effort, an interesting and readable discussion, and another higher notch on the scoreboard of critical scholarship that deserves wide examination and close attention." —Geophysics This fascinating book describes the rise and fall and rebirth of continental drift theory in this century. It uses the recent revolution in geoscientinsts' beliefs about the earth to examine questions such as, How does scientific knowledge develop and change? The book also explores how well different perspectives help us to understand revolutionary change in science.
