Available in PDF, EPUB and Kindle. Book excerpt: To assess recovery of pink salmon (Oncorhynchus gorbuscha) spawning habitat in Prince William Sound after the Exxon Valdez oil spill, we analyzed sediment samples from William Sound after the Exxon Valdez oil spill, we analyzed sediment samples from stream deltas from 1989-1991 and 1995. In 1989, petroleum hydrocarbon concentration at 172 stream deltas (1-8 samples each) was bimodally distributed: 85 deltas had no detectable petroleum hydrocarbons (detection limit 2 pg/g); 87 deltas had 2-45,OOO pg/g. In 1995, petroleum hydrocarbons were still detected at eight of nine oiled streams we resampled, with mean concentration up to 242 pg/g. The polynuclear aromatic hydrocarbon (PAH) fraction was also analyzed to determine origin and toxic potential. The PAH in 1995 consisted mostly of the more toxic compounds with high molecular weight. Composition was consistent with weathered Exxon Valdez oil, and total PAH concentration ranged up to 1,300 ng/g. Interpolation between 1989 and 1995 indicated that PAH concentration exceeded 3,800 ng/g (minimum sediment concentration that reduces salmon embryo survival in the laboratory) at some stream deltas through 1993, but all streams were below this level by 1994. We conclude that tidal leaching of residual PAH into incubation substrate could explain persistent impaired embryo survival in pink salmon through 1993, and that spawning habitat had recovered by 1994.

This book was released on 2003 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Results show that drainage of groundwater from beaches into surface and subsurface stream water provides a mechanism for contaminant exchange providing evidence that pink salmon (Oncorhynchus gorbuscha) spawning habitat in Prince William Sound was contaminated by Exxon Valdez oil. Low levels of polynuclear aromatic hydrocarbon (PAH) from the Exxon Valdez remain in two of six previously heavily oiled streams examined leading to the opinion that most spawning habitat has recovered or is recovering. Exposure of pink salmon embryos from five brood years to similar levels of hydrocarbons showed a variety of lethal and sublethal responses.

Available in PDF, EPUB and Kindle. Book excerpt: 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

Available in PDF, EPUB and Kindle. Book excerpt: Coastal ecosystems are centres of high biological productivity, but their conservation is often threatened by numerous and complex environmental factors. Citing examples from the major littoral habitats worldwide, such as sandy beaches, salt marshes and mangrove swamps, this text characterises the biodiversity of coastline environments and highlights important aspects of their maintenance and preservation, aided by the analysis of key representative species. Leaders in the field provide reviews of the foremost threats to coastal networks, including the effects of climate change, invasive species and major pollution incidents such as oil spills. Further discussion underscores the intricacies of measuring and managing coastline species in the field, taking into account the difficulties in quantifying biodiversity loss due to indirect cascading effects and trophic skew. Synthesising the current state of species richness with present and projected environmental pressures, the book ultimately establishes a research agenda for implementing and improving conservation practices moving forward.

This book was released on 1995 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper presents results of a field program designed to monitor the status of wildstock pink salmon populations in Prince William Sound following the Exxon Valdez oil spill. Field counts of spawning salmon were conducted each year from 1989 through 1992 to test for spill effects on the distribution and abundance of pink salmon adults spawning in selected streams in the southwestern portion of Prince William Sound, including streams from the most heavily oiled areas. Counts of whole-stream and intertidal escapement density were statistically compared for 40 study streams in 1989 and for a subset of those streams in successive years. Measurements of residual hydrocarbons were made from stream-bed sediments to test for correlations with spawning behavior.
