Appendix B: Detailed Model Results for the Eastern Tropical Pacific Table B-1. Summary of model validation statistics for final offshore spotted dolphin density models in the ETP built on 1998-2003 SWFSC survey data and tested on 2006 SWFSC survey data. Obs/Pred = ratio of stratified line-transect to model predicted density estimates. Obs = observed number of groups multiplied by the observed average group size. Pred = predicted number of groups multiplied by the predicted group size. Statistics are provided for each year separately and for all years pooled, and for each stratum separately and the study area as a whole. 1998 1999 2000 Stratum Obs/Pred Obs Pred Obs/Pred Obs Pred Obs/Pred Obs Pred Costa Rica Dome 0.576 1891.892 3282.351 0.773 1040.846 1346.893 0.349 676.043 1934.994 West Baja Peninsula 2.060 141.170 68.527 0.000 0.000 48.169 0.000 0.000 118.951 Equatorial Cold Tongue 0.979 1653.173 1688.505 1.007 694.095 689.443 0.758 658.106 868.238 Eastern Pacific Warm Pool 0.835 7764.942 9295.248 0.964 5388.636 5591.076 1.391 8615.090 6191.724 Oligotrophic Offshore 1.061 3144.419 2963.754 1.260 2704.267 2145.824 1.196 2749.437 2299.805 North Equatorial Countercurrent 0.939 2571.694 2737.405 1.377 2419.456 1756.725 1.147 2180.940 1901.450 North Equatorial Current 0.787 2611.924 3320.076 0.647 1512.637 2336.121 1.013 2588.480 2556.186 Study Area 0.823 14761.266 17935.898 1.003 10200.934 10170.228 1.087 12923.546 11884.147 2003 2006 All Years Stratum Obs/Pred Obs Pred Obs/Pred Obs Pred Obs/Pred Obs Pred Costa Rica Dome 1.359 1292.793 951.523 0.408 732.203 1793.012 0.605 5633.777 9308.772 West Baja Peninsula 0.000 0.000 107.592 0.000 0.000 59.872 0.350 141.170 403.110 Equatorial Cold Tongue 1.868 1064.092 569.547 0.690 721.515 1045.159 0.986 4790.981 4860.891 Eastern Pacific Warm Pool 1.218 6303.567 5174.624 1.676 7219.894 4306.944 1.155 35292.129 30559.616 Oligotrophic Offshore 0.268 225.750 843.174 0.934 1718.610 1841.029 1.044 10542.483 10093.586 North Equatorial Countercurrent 0.796 641.340 805.342 1.261 1965.699 1559.164 1.116 9779.129 8760.085 North Equatorial Current 0.471 830.093 1761.382 1.022 2034.319 1990.549 0.801 9577.454 11964.315 Study Area 1.138 8886.202 7811.586 1.102 10650.626 9669.171 0.999 57422.573 57471.029 133
