Available in PDF, EPUB and Kindle. Book excerpt: On January 8 and 9, 2009, the Ocean Studies Board of the National Research Council, in response to a request from the Office of Naval Research, hosted the "Oceanography in 2025" workshop. The goal of the workshop was to bring together scientists, engineers, and technologists to explore future directions in oceanography, with an emphasis on physical processes. The focus centered on research and technology needs, trends, and barriers that may impact the field of oceanography over the next 16 years, and highlighted specific areas of interest: submesoscale processes, air-sea interactions, basic and applied research, instrumentation and vehicles, ocean infrastructure, and education. To guide the white papers and drive discussions, four questions were posed to participants: What research questions could be answered? What will remain unanswered? What new technologies could be developed? How will research be conducted?

Available in PDF, EPUB and Kindle. Book excerpt: " ... as soon as one has traversed the greater part of the wild sea, one comes upon such a huge quantity of ice that nowhere in the whole world has the like been known." "This ice is of a wonderful nature. It lies at times quite still, as one would expect, with openings or large fjords in it; but sometimes its movement is so strong and rapid as to equal that of a ship running before the wind, and it drifts against the wind as often as with it."

Download or read book Whither the Arctic Ocean written by Guillermo Auad and published by Fundacion BBVA. This book was released on 2021-05-01 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change in the Arctic Ocean has stirred a remarkable surge of interest and concern. Study after study has revealed the astonishing speed of physical, chemical, ecological, and economic change throughout the expanse of the Arctic. What is more, the consequences of the changing Arctic are not restricted to the Arctic itself, but affect everyone in the Northern Hemisphere, ranging as they do from extreme weather to resource availability and food security, with implications for politics, economics, and sociology. The challenge is to comprehend the full extent and variety of these consequences, and meeting this challenge will demand a multi- and transdisciplinary understanding. Only by this means can we hope to map out a knowledge-based ecosystem and move toward knowledge-based resource management—the essential precondition for any sustainable future. In this book, leading international experts, from many felds of science and across the entire pan-Arctic region, give their specifc takes on where the Arctic Ocean is heading. All have taken care in their writing not to exclude non-experts, in the conviction that multi- and transdisciplinarity can only be achieved when communication and outreach are not tribal in nature. The recurrent guiding theme throughout these pages is “Whith -er the Arctic Ocean?” Taken in concert, the essays synthesize the current state of scientifc knowledge to project how climate change may impact on the Arctic Ocean and the continents around it. How can and how should we prepare for the imminent future that is already lapping at the threshold of the commons? What readers will hopefully take from this multi- and transdisciplinary endeavor is not the individual perspective of each contribution, but the picture that emerges across the entire suite of essays. As we move into a near future that will encompass both the probable and surprises, this book attempts to conjure the multi-dimensional space in which a sustainable future must be brought into being.

Download or read book Sea Ice written by David N. Thomas and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sea ice, which covers up to 7% of the planet’s surface, is a major component of the world’s oceans, partly driving ocean circulation and global climate patterns. It provides a habitat for a rich diversity of marine organisms, and is an extremely valuable source of information in studies of global climate change and the evolution of present day life forms. Increasingly sea ice is being used as a proxy for extraterrestrial ice covered systems. Sea Ice provides a comprehensive review of our current available knowledge of polar pack ice, the study of which is severely constrained by the logistic difficulties of working in such harsh and remote regions of the earth. The book’s editors, Drs Thomas and Dieckmann have drawn together an impressive group of international contributing authors, providing a well-edited and integrated volume, which will stand for many years as the standard work on the subject. Contents of the book include details of the growth, microstructure and properties of sea ice, large-scale variations in thickness and characteristics, its primary production, micro-and macrobiology, sea ice as a habitat for birds and mammals, sea ice biogeochemistry, particulate flux, and the distribution and significance of palaeo sea ice. Sea Ice is an essential purchase for oceanographers and marine scientists, environmental scientists, biologists, geochemists and geologists. All those involved in the study of global climate change will find this book to contain a wealth of important information. All libraries in universities and research establishments where these subjects are studied and taught will need multiple copies on their shelves. David Thomas is at the School of Ocean Sciences, University of Wales, Bangor, UK. Gerhard Dieckmann is at the Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany
Download or read book Ocean Circulation and Climate written by Cecilie Mauritzen and published by Elsevier Inc. Chapters. This book was released on 2013-10-22 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations made during the 1990s and 2000s indicate that the Arctic physical environment and associated ecosystem are undergoing remarkable changes. The observed reduction in Arctic sea ice extent is arguably the strongest, most powerful visual symbol of climate change. The Arctic Ocean is changing as well. Here we discuss, from an observational point of view, the present understanding of the circulation, water masses, and stratification of the Arctic Ocean, highlighting the changes that have taken place during the past few decades. Many of these ocean signals evolve rapidly, making it essential that the state of the Arctic/Subarctic is observed continually, using all the recent advances that have been made in high-latitude monitoring and in Earth System understanding. Taking recent investigations of the Arctic atmosphere and sea ice as guides, we deem it likely that signatures of anthropogenic climate change in the Arctic/Subarctic Seas will begin to emerge above the high level of natural variability within the next decade.
Download or read book The Northern North Atlantic written by Priska Schäfer and published by Springer Science & Business Media. This book was released on 2001-04-02 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: The northern North Atlantic is one of the regions most sensitive to past and present global changes. This book integrates the results of an interdisciplinary project studying the properties of the Greenland-Iceland-Norwegian Seas and the processes of pelagic and benthic particle formation, particle transport, and deposition in the deep-sea sediments. Ice-related and biogeochemical processes have been investigated to decipher the spatial and temporal variability of the production and fate of organic carbon in this region. Isotopic stratigraphy, microfossil assemblages and paleotemperatures are combined to reconstruct paleoceanographic conditions and to model past climatic changes in the Late Quaternary. The Greenland-Iceland-Norwegian Seas can now be considered one of the best studied subbasins of the world`s oceans.

Download or read book Decadal Freshening and Warming of the Western Arctic Upper Ocean written by Russell G. Ingersoll and published by . This book was released on 2010 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Upper-ocean freshness and heat content are important components of the coupled Arctic system, especially within the context on ongoing Arctic change. High resolution hydrographic profile data collected from Arctic research expeditions and autonomous systems are analyzed to generate a 30+ year record of upper-ocean fresh water content and heat content evolution. Vertical integrals of Heat Content (HC) and Fresh Water Content (FWC) are calculated in three layers: Surface(Sfc)-150m, Sfc-Mixed Layer Depth (MLD), and MLD-150m. Vertical averages of Departure From Freezing Point (DFFP), Salinity(z), and Temperature(z) are also calculated for all three layers. Spatial and temporal constraints allow for seasonal and regional signals to be separated from decadal trend signals. Sub-regions (Beaufort Shelf, Beaufort Gyre, and Trans-polar Drift) are chosen with respect to hydrographically uniform characteristics. In the Beaufort Gyre, Sfc-150m vertically averaged salinity decreases by -0.04 psu/yr while FWC increases by +0.15 m/yr, and HC rises by +3.8 MJ/m2/yr. Mixed layer vs. Halocline trend separation (Sfc-MLD vs. MLD-150m) shows accumulation of FWC in both layers definitively, while the halocline hosts almost all of the accumulation of HC. The trends in FWC are consistent with the observed decline in Arctic sea ice cover.

Download or read book The Arctic Seas written by Yvonne Herman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 887 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arctic region has long held a fascination for explorers and scientists of many countries. Despite the numerous voyages of exploration, the na ture of the central Arctic was unknown only 90 years ago; it was believed to be a shallow sea dotted with islands. During Nansen's historic voyage on the polarship Fram, which commenced in 1893, the great depth of the central basin was discovered. In the Soviet Union, investigation of the Arctic Ocean became national policy after 1917. Today research at several scientific institutions there is devoted primarily to the study of the North Polar Ocean and seas. The systematic exploration of the Arctic by the United States com menced in 1951. Research has been conducted year-round from drifting ice islands, which are tabular fragments of glacier ice that break away from ice shelves. Most frequently, ice islands originate off the northern coast of Ellesmere Island. These research platforms are occupied as weather sta tions, as well as for oceanographic and geophysical studies. Several inter national projects, conducted by Canadian, European, and U. S. groups, have been underway during the last three decades. Although much new data have accumulated since the publication of the Marine Geology and Oceanography of the Arctic Seas volume in 1974 (Yvonne Herman, ed. ), in various fields of polar research-including present-day ice cover, hydrogra phy, fauna, flora, and geology-many questions remain to be answered.
