Figure 2 
Time series of annual catch anomalies for 14 species or species groups commonly captured during 
bottom trawl surveys conducted during 1991-2012 in Port Madison, Puget Sound, Washington. Gray 
lines depict instances where the linear or change-point model provided the best fit to the data. 
Graph in the bottom right corner depicts total survey catch (unstandardized). Catch anomalies are 
the yearly averaged differences between each trawl tow and the average catch rate (number of fish) 
for all tows collected at the same depth and time of day. 
Time series of anomalies in sub-mixed-layer tempera- 
ture and surface salinity were generally consistent with 
each other between the 2 monitored sites (Fig. 4). The 
data indicated exceptionally warm years in 1992, 1994, 
1998, 2003, and 2004 and cool years in 1993, 1999-2002, 
and 2008. For each of the 2 sites, temperature time se- 
ries indicated neither a distinct shift near 1997-1999 
nor any other change point or linear trend (Table 3). 
The time series of surface salinity for the West Point 
site was generally more variable than the time series for 
the Jefferson Head site, yet both time series showed the 
same years as exceptionally high or low. At both sites, 
1992, 2001, 2004, and 2008 were high-salinity years and 
1991 and 1997 were low-salinity years. There was no 
indication of a linear trend or change point in the sur- 
face salinity at West Point (Table 3), but the surface sa- 
linity at Jefferson Head showed a positive linear trend 
(change of roughly 0.04 ppt/year).
