Whither the Arctic Ocean?


Book Description

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.




The Nordic Seas


Book Description

" ... 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." Kongespeilet - 1250 A.D. ("The Mirror of Kings") Modern societies require increasing amounts influence on the water mass and on the resulting of scientific information about the environment total environment of the region; therefore, cer tain of its characteristics will necessarily be in whieh they live and work. For the seas this information must describe the air above the sea, included.




Arctic Sea Ice Ecology


Book Description

The book on sea ice ecology is the ecology of sea ice algae and other microorganism as bacteria, meiofauna, and viruses residing inside or at the bottom of the sea ice, called the sympagic biota. Organisms as seals, fish, birds, and Polar bears relies on sea ice but are not part of this biota. A distinct feature of this ecosystem, is the disappearance (melt) every summer and re-establishing in autumn and winter. The book is organized seasonally describing the physical, optical, biological, and geochemical conditions typical of the seasons: autumn, winter, and spring. These are exemplified with case studies based on author’s fieldwork in Greenland, the Arctic Ocean, and Antarctica but focused on Arctic conditions. The sea ice ecosystem is described in the context of climate change, interests, and effects of a decreasing summer ice extent in the Arctic Ocean. The book contains an up to date description of most relevant methods and techniques applied in sea ice ecology research. This book will appeal to university students at Masters or PhD levels reading biology, geosciences, and chemistry.




Changing Arctic Ocean


Book Description

The Arctic is the most northern part of our Earth. It is a huge area that spans over several countries including; Canada, Denmark (Greenland), Finland, Iceland, Norway, Sweden, Russia, and the USA. However, the largest part of the Arctic is not on land but is covered by water – the Arctic Ocean. For hundreds of thousands of years, large parts of the Arctic Ocean were covered by ice all year around. Many animals, such as polar bears, Arctic foxes, seals, fish and birds, and even some people have made this icy place their home. They have learned to live with the ice, and some animals even need it to live. But recently, things in the Arctic have been changing. You have probably already heard a lot about Climate Change. Climate Change impacts the long-term weather (climate) everywhere on our planet. Many areas get warmer, some get colder, and everywhere we see more extreme or unusual weather, such as storms, floods or droughts. But nowhere is Climate Change happening as fast as in the Arctic. You might have also heard about the “2°C goal”. This is a goal that many governments around the world have agreed to. The plan is essentially to make sure the average global warming of our atmosphere stays at less than 2°C compared to what people like to call “pre-industrial time” (the year 1948 is used as a reference). Right now, most of the world is at around 0.8°C warming. In the Arctic, we are already at 2.3°C warming – that is 0.3°C above what should be the absolute maximum according to the “2°C goal”. Now you probably ask why it is so bad that the Arctic is getting a bit warmer. That should make it a nicer place to live, right? Unfortunately, the warm temperature means that the ice that has covered the Arctic Ocean for all this time is melting. It looks like that will change the Arctic Ocean forever and with it the animals and people that call the Arctic their home. In this collection, we want to tell you what we, as scientists, know about the changes in the Arctic; how we investigate these changes and what we have learned from our travels to the Arctic and the analyses we do in our research institutes. We will tell you about how the higher temperatures in the Arctic change the ice. How very tiny animals can have a huge impact. We want to introduce you to life in the ice, under the ice, and at the seafloor. We will talk about processes that make the Arctic Ocean so special and chemicals that can travel from our homes and cities all the way to the Arctic.




Arctic Environment Variability in the Context of Global Change


Book Description

The main focus of this book is the study of environmental dynamics in the Arctic, coupled with ecosystem dynamics. Particular emphasis has been placed on problems of the composition of the Arctic atmosphere, as well as changes in the composition due to human impacts. The book also analyzes observational data and numerical modeling results that characterize the Arctic basin pollution dynamics and its impact on ecosystems. Other topics covered include problems of general circulation in the atmosphere and oceans, beginning with the 1930s when the Arctic was regarded as the kitchen of global weather and climate.




Polar Oceans Governance in an Era of Environmental Change


Book Description

Arctic Climate Change


Book Description

The Arctic is now experiencing some of the most rapid and severe climate change on earth. Over the next 100 years, climate change is expected to accelerate, contributing to major physical, ecological, social, and economic changes, many of which have already begun. Changes in arctic climate will also affect the rest of the world through increased global warming and rising sea levels. The volume addresses the following major topics: - Research results in observing aspects of the Arctic climate system and its processes across a range of time and space scales - Representation of cryospheric, atmospheric, and oceanic processes in models, including simulation of their interaction with coupled models - Our understanding of the role of the Arctic in the global climate system, its response to large-scale climate variations, and the processes involved.




The Pacific Arctic Region


Book Description

The Pacific Arctic region is experiencing rapid sea ice retreat, seawater warming, ocean acidification and biological response. Physical and biogeochemical modeling indicates the potential for step-function changes to the overall marine ecosystem. This synthesis book was coordinated within the Pacific Arctic Group, a network of international partners working in the Pacific Arctic. Chapter topics range from atmospheric and physical sciences to chemical processing and biological response to changing environmental conditions. Physical and biogeochemical modeling results highlight the need for data collection and interdisciplinary modeling activities to track and forecast the changing ecosystem of the Pacific Arctic with climate change.




Arctic Studies


Book Description

The Arctic region is the keystone to understanding the present status ofcurrently ongoing Earth systems and to predicting future imagesof our planet as viewed from northern high latitudes. The Arctic region,composed of ice-covered Arctic ocean in its center and surroundingfragmentation of the major continents, has been investigatedduring the last half century through all kinds of scientific studies:bioscience, physical sciences, geoscience, oceanography, and environmental studies, together with the technological domain. This book covers topics on the recent developments of all kinds of scientific research in and around the Arctic region, with a view to monitoring the current variations in the extreme environment, affected by remarkable changes in temperature and sea-ice extent, mass loss of ice-sheet and glaciers, and variations in marine and terrestrial ecosystems, including human activities.
