Paleolimnology of selected lakes in the Southwest Alaska Network: understanding past trends of salmon abundance and lake productivity
Finney BP. 2005. Paleolimnology of selected lakes in the Southwest Alaska Network: understanding past trends of salmon abundance and lake productivity. National Park Service. Fairbanks, AK
Paleolimnological techniques on selected lakes in the Southwest Alaska Network of the National Park Service are utilized in this project to better understand processes and long-term trends in their biota and environments, with a focus on sockeye salmon lakes. Past changes in sockeye salmon abundance will be determined using stable nitrogen isotope analysis of sockeye nursery lake sediment cores. Data will be developed to reconstruct lake productivity abd sockeye salmon abundance over the past 500 to 10,000 years. This data will help define the natural variability of sockeye salmon in these systems, and its relationship to past changes in climate, landscape processes, ocean condition and commercial fishing. In this second annual report of the three-year project, field and laboratory results from the second year (2004) are highlighted.
