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.

This book introduces children to the Arctic Ocean, looking at both its relatively shallow continental shelf and its underwater mountains. These features are explored using key geography terms. Children are encouraged to use geographical skills to locate information by reading maps and interpreting simple keys. This series complements the Introducing Continents series.

The flux, preservation, and accumulation of organic carbon in marine systems are controlled by various mechanisms including primary p- duction of the surface water, supply of terrigenous organic matter from the surrounding continents, biogeochemical processes in the water column and at the seafloor, and sedimentation rate. For the world's oceans, phytoplankton productivity is by far the largest organic carbon 9 source, estimated to be about 30 to 50 Gt (10 tonnes) per year (Berger et al. 1989; Hedges and Keil 1995). By comparison, rivers contribute -1 about 0. 15 to 0. 23 Gt y of particulate organi.

"The model predicts the ice thickness, and the temperature and salinity of the water in the upper layer for the four regions. Also determined are the water temperature and salinity for the lower layer in the Arctic Ocean box. The convective state of any given region, i.e., whether it is in an active overturning mode or not, is also obtained continuously." --

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.

Oceans account for more than 25% of anthropogenic CO2 removal from the atmosphere. Changes in our global climate have affected the Arctic Ocean in particular, resulting in increasing rates of warming and record-low sea ice extent, which for example, in the summer of 2012, was only half of the average over the previous three decades. It is unclear how these changes in the Arctic Ocean may affect biological productivity, which is one of the main drivers of the oceanic carbon cycle as CO2 is consumed through photosynthesis and released through respiration. In order to investigate how these changes may influence the efficacy of the Arctic Ocean as a carbon sink, we calculated the gross oxygen production (GOP), which is the rate of total photosynthesis, and the net community production (NCP), which is the rate of photosynthesis minus community respiration and thus represents the strength of the carbon sink. The chemical gas tracers, triple oxygen isotopes and O2/Ar ratios, as measured in samples from the surface waters of the Beaufort Gyre region of the Canada Basin, were used to quantify gross oxygen production and net community production, respectively, in late summer and early fall over six years (2011-2016). We examined the effects of location, ice cover, chlorophyll-a, season, and more to better understand the collective impact of these physical conditions on biological productivity rates. Over these six years, mean GOP rates ranged from 9.1 ± 1 mmol O2 m−2 d−1 to 4 ± 4 mmol O2 m−2 d−1 and mean NCP rates ranged from 1.1 ± .2 mmol O2 m−2 d−1 to 2.5 ± .2 mmol O2 m−2 d−1. Analyzing inter-annual variations in these rates can enlighten our understanding of how dramatic changes in the global climate may impact the ability of this region in the Arctic Ocean to remove carbon dioxide from the atmosphere.

This book is dedicated to the study of structure and transport of deep and bottom waters above and through underwater channels of the Atlantic Ocean. The study is based on recent observations, analysis of historical data, and literature reviews. This approach allows us to understand how water transport and water mass prop- ties have changed over the last years and decades. The focus of our study is on the propagation of bottom waters in the Atlantic Ocean based on new field data at key points. At the end of the 1920s, the first integral study of water masses and bottom topography of the Central and South Atlantic was carried out from the German - search vessel Meteor. This German Atlantic Expedition was one of the first cruises equipped with the newly developed echo sounder (fathometer): an obligatory p- requisite for the investigation of bottom morphology in the deep sea on an - erational base. The results of the expedition were published by Wüst, Defant, and colleagues in the multivolume METEOR publication series starting with the cruise report by the ship’s commander (Spiess 1928, 1932). Historically, this series of p- lications, intermittently interrupted by World War II, was the basis for many years of research into the development of modern concepts about Atlantic water masses and their circulation schemes.
