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

When the Exxon Valdez oil tanker ran aground on Bligh Reef in Alaska in 1989 and spilled 11 million gallons of oil, it changed Prince William Sound forever. The catastrophe disrupted the region’s biological system, killing countless animals and poisoning habitats that to this day no longer support some of the local species. The effects have also profoundly altered the way people use this region. Nearly three decades later, changes in recreation use run counter to what was initially expected. Instead of avoiding Prince William Sound, tourists and visitors flock there. Economic revitalization efforts have resulted in increased wilderness access as new commercial enterprises offer nature tourism in remote bays and fjords. This increased visitation has caused concerns that the wilderness may again be threatened—not by oil but rather by the very humans seeking those wilderness experiences. In Sustaining Wildlands, scientists and managers, along with local community residents, address what has come to be a central paradox in public lands management: the need to accommodate increasing human use while reducing the environmental impact of those activities. This volume draws on diverse efforts and perspectives to dissect this paradox, offering an alternative approach where human use is central to sustaining wildlands and recovering a damaged ecosystem like Prince William Sound.

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.

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.

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.
