Pinnipeds<br />
Figure 17. Cetacean Behaviors by Construction Type<br />
During both SSV and V procedures, pinnipeds most often were “looking.” During SSV<br />
procedures, pinnipeds were most often “looking” (n=6; 4.6%) and “milling” (n=4; 3.2%)<br />
(Table 22, Figure 18). During V, pinnipeds were most often “swimming” (n=24; 19.1%),<br />
“looking” (n=23; 18.3%), and “diving” (n=19; 15.1%). All behaviors were seen with greater<br />
frequency during V than SSV, including more “looking,” “diving,” “swimming,” and “traveling”<br />
(Table 22, Figure 18).<br />
