Long Term Ecological Change In The Northern Gulf Of Alaska

This comprehensive text is a major synthesis on ecological change in the Gulf of Alaska. It encompasses the structural and annual changes, forces of change, long-ecological changes in the atmosphere and ocean, plankton, fish, birds and mammals, and the effects of the 1989 Exxon Valdez Oil Spill. With 5 major sections, Long-term Ecological Change in the Northern Gulf of Alaska first describes the physical features, the atmosphere and physical oceanography, the annual production cycle, the forage base for higher animals and trophic transfer, and the adaptations for survival in this changing environment for 9 portal species. Then, the major forces of change are introduced: climate, geophysics, fisheries and harvesting, species interactions, disease and contaminants. Next, the long-term records of change in physical factors and biological populations are presented, as well as the potential reasons for the biological changes. Following is the history of the Exxon Valdez oil spill and its long-term effects. And, finally, the emergent properties of the ecosystem are discussed and an attempt is made to weigh the importance of the major forcing factors in terms of their temporal and spatial scales of influence. * Examines important data on long-term change in the ecosystem and the forcing factors that are responsible for it * Provides an account of the 1989 Exxon Valdez oil spill with emphasis on the long-term effects * Describes the effects of climate change, geophysical change, species interactions, harvesting, disease, the 1989 oil spill, and marine contaminants on key populations of marine organisms

This report provides guidance to the Gulf Ecosystem Monitoring (GEM) program to help ensure that it is based on a a science plan that is robust, far-reaching, and scientifically sound. The report commends the Trustee Council for its foresight in setting aside funds to create a trust fund to provide long-term research support; it notes that the GEM program offers an unparalleled opportunity to increase understanding of how large marine ecosystems function and change over time. The report outlines elements of a sound long-term science plan, including conceptual foundation, scope and geographic focus, organizational structure, community involvement, data and information management, and synthesis, modeling, and evaluation.

The latest volume in the LTER series, this book presents the results and finding of the Long-Term Ecological Research site in the Alaskan Arctic, discussing Arctic ecology from a variety of perspectives and disciplines.

The North is changing at an unprecedented rate as industrial development and the climate crisis disrupt not only the environment but also long-standing relationships to the land and traditional means of livelihood. Memory and Landscape: Indigenous Responses to a Changing North explores the ways in which Indigenous peoples in the Arctic have adapted to challenging circumstances, including past cultural and environmental changes. In this beautifully illustrated volume, contributors document how Indigenous communities in Alaska, northern Canada, Greenland, and Siberia are seeking ways to maintain and strengthen their cultural identity while also embracing forces of disruption. Indigenous and non-Indigenous contributors bring together oral history and scholarly research from disciplines such as linguistics, archaeology, and ethnohistory. With an emphasis on Indigenous place names, this volume illuminates how the land—and the memories that are inextricably tied to it—continue to define Indigenous identity. The perspectives presented here also serve to underscore the value of Indigenous knowledge and its essential place in future studies of the Arctic.

Covering 71 percent of the planet, these saline bodies of water provided the unique conditions necessary for the building blocks of life to form billions of years ago. This book explains how our oceans continue to support and influence life in important ways: by providing the largest global source of protein in the form of fish populations, by creating and influencing weather systems, and by absorbing waste streams such as airborne carbon. It is shown how oceans have an almost magnetic draw—almost half of the world’s population lives within a few hours of an ocean. Although oceans are vast in size, exceeding 328 million cubic miles (1.37 billion cubic kilometers), they have been influenced by and have influenced humans in numerous ways. The book includes three detailed case studies. The first focuses on the most remote locations along the Mid-Atlantic Ridge, where new ocean floor is being formed twenty-thousand feet underwater. The second considers the Maldives, a string of islands in the Indian Ocean, where increasing sea levels may force residents to abandon some communities by 2020. The third describes the North Sea at the edge of the Arctic Ocean, where fishing stocks have been dangerously depleted as a result of multiple nations’ unrelenting removal of the smallest and largest species.

Over the past 4 billion years, microorganisms have contributed to shaping the earth and making it more habitable for higher forms of life. They are remarkable in their metabolic diversity and their ability to harvest energy from oxidation and reduction reactions. Research on these microbiological processes has led to the newly evolving fields of geomicrobiology and biogeochemistry, linking the geosphere and the biosphere. This volume of the Soil Biology series provides an overview of the biogeochemical processes and the microorganisms involved, with an emphasis on the industrial applications. Topics treated include aspects such as bioremediation of contaminated environments, biomining, biotechnological applications of extremophiles, subsurface petroleum microbiology, enhanced oil recovery using microbes and their products, metal extraction from soil, soil elemental cycling and plant nutrition.

Chronicling her quest for wildness and home in Alaska, naturalist Marilyn Sigman writes lyrically about the history of natural abundance and human notions of wealth—from seals to shellfish to sea otters to herring, halibut, and salmon—in Alaska’s iconic Kachemak Bay. Kachemak Bay is a place where people and the living resources they depend on have ebbed and flowed for thousands of years. The forces of the earth are dynamic here: they can change in an instant, shaking the ground beneath your feet or overturning kayaks in a rushing wave. Glaciers have advanced and receded over centuries. The climate, like the ocean, has shifted from warmer to colder and back again in a matter of decades. The ocean food web has been shuffled from bottom to top again and again. In Entangled, Sigman contemplates the patterns of people staying and leaving, of settlement and displacement, nesting her own journey to Kachemak Bay within diasporas of her Jewish ancestors and of ancient peoples from Asia to the southern coast of Alaska. Along the way she weaves in scientific facts about the region as well as the stories told by Alaska’s indigenous peoples. It is a rhapsodic introduction to this stunning region and a siren call to protect the land’s natural resources in the face of a warming, changing world.
