Figure 23. Permuted data matrix of hierarchical cluster analyses of fish weighted densities

by modified primary substrates (matrix, both columns and rows, simultaneously) with juvenile

Sebastes removed. Distinct clusters in dendrograms are represented by different colored branches.

Figure 26a. Differential GPS positions indicating presence of the fishes, Sebastes melanops, Sebastes

mystinus, Sebastes pinniger, and Hexagrammos decagrammus at PGER. Positions are superimposed on

ROV dive transects along with bathymetry over the analog sidescan sonar image.

Figure 26b. Differential GPS positions indicating presence of the fishes in Figure 26a on ROV dive transects

in the northern portion of PGER. Inside bars represent modified primary substrate types as determined from

ROV videotape. Outside bars represent relief categories.

in the southern portion of PGER. Inside bars represent modified primary substrate types as determined from

ROV videotape. Outside bars represent relief categories.
