Satellite-based study of water quality of Chilko lake (British Columbia, Canada): Impact on Sockeye salmon

Chilko Lake sockeye constitute one of the largest salmon stocks in the Pacific Northwest, for which Fisheries and Oceans Canada has maintained a 55-year record, including partitioned freshwater and marine survival. The lake was also the site of fertilization experiments in the 1970s-1990s. This paper examined the use of spaceborne data from MERIS and LANDSAT collected over the Chilko Lake watershed for the purpose of generating long time series of lake chlorophyll and water temperature, testing and validating standard chlorophyll algorithms against in situ measurements, comparing Sockeye survival with lake variables, and assessing the state of glaciers in the watershed.
