The actual 2006–15 and projected 2014–15 abundance for <i>M</i>. <i>franciscanus</i> in 5 basins of the Salish Sea and the Outer Coast.

<p>Grey line marks the epidemic onset. Note: Abundance = Density Score x SF, where Density Score = [(nSx1)+(nFx2)+(nMx3)+(nAx4)] / (nS + nF + nM + nA). Here nS, nF, nM, and nA represent the number of times each abundance category was assigned for a given species.</p
