Description This data comes primarily from the Columbia River DART database managed by the University of Washington (http://www.cbr.washington.edu/dart/dart.html). Column headings: Y=Year of adult migration; D=median migrate date of adult sockeye salmon (DART); S1997=selection differential calculated in R based on the selection function fit to 1997 mark-recapture data; F=mean June flow in cms at Bonneville Dam (DART); FP=day of maximum flow in Julian days, calculated from daily flow data from DART; T=mean June temperature at Bonneville Dam(DART); Umar, Uap,Umay=Upwelling index for March, April, and May at 45N from Pacific Fisheries Environmental Laboratory. 2008. Upwelling Index. Environmental Research Division, NOAA-Fisheries, SWFSC http://www.pfeg.noaa.gov/javamenu.html, accessed June 2008. WRI=total sockeye count at Wells Dam divided by the total count at Rock Island Dam (DART); PDO=Index of the Pacific Decadal Oscillation averaged from Dec-Jun from Mantua, N. 2005. PDO Index, http://jisao.washington.edu/pdo/PDO.latest; NPGO=Di Lorenzo, E., N. Schneider, K. M. Cobb, K. Chhak, P. J. S. Franks, A. J. Miller, J. C. McWilliams et al. 2008. North Pacific Gyre Oscillation NPGO Index available at http://eros.eas.gatech.edu/npgo/; NPI= North Pacific Index, from Trenberth, K., and J. Hurrell. 2009. Boulder, USA, Climate Analysis Section, NCAR. The next set of columns are the difference in the index from year t-4 to year t, except for S4, which is simply shifted by 4 years. CumS4 reflects the cumulative selection at 4-generation intervals up to that year. D.sd is the standard deviation of the migration period, and betaS is the selection differential standardized by the standard deviation of the trait (i.e., D.sd)
