Nudibranch Survey Results

We surveyed nudibranchs on two dives, targeting different depths on the two dives.  The first survey was conducted by paralleling the 60' survey line, slightly deeper than the line.  The result was a survey averaging 70'.  During our 40 minute survey, we covered the entire area that the survey line covered, starting at the end of the line on the southwest side, and completing the horseshoe at the southeast side. 

The second survey was conducted along the bottom of the pinnacle, including some of the rubble areas at the base of the pinnacle, averaging a depth of 95'.  This survey was conducted entirely on the east side of the pinnacle, and included portions of the pinnacle extending south of the end of the survey line.  On both dives, we swam along the survey area, counting any species of slug that we passed.  In addition to the species noted during the survey, two Doto amyra were spotted on the survey areas (one on a setup dive, and one by the photography team).  So we know that this species was present on the pinnacle as well.
