can be seen from Table C-2 and Figure C-4 the concentrations of Cd, Cu, Hg, 

 In, and Fe lie conspicuously outside the upper 95% conficence limit of the 

 baseline data. Only the concentration of Cd remains within the 95% confidence 

 limits. The location of this reference site may be subject to change unless 

 a viable explanation for the significant changes in metal concentration can 

 be explained . 



Benthic Macrofauna 



Table C-3 presents the numeric density data for* the major species obtained 



at the Isles of Shoals disposal area during December, 1977. A fairly diverse 



population with 14 major species comprising 77% of the total number of indi- 

 viduals was found in this area. 



Fisheries 



There are a number of regulations which effect the pattern of fisheries 

 in this area. The marine boundries of Maine and New Hampshire have not been 

 established beyond the Isles of Shoals. Two possible borders are shown on 

 Fig. C-5: a median line between Cedar Island Ledge and Anderson Ledge, and a 

 line due east of the ledges. The study site is 1% and 1 miles from these lines 

 and in Maine water. The definition of these borders is important because Maine 

 and New Hampshire waters can be used for lobstering only by residents of each 

 state. Dragging can be done in non-home states with a licence, but dragging 

 can not be done within 2 miles of New Hampshire. In addition to these regula- 

 tions, there is a tradition of only Isles of Shoals - connected fishermen 

 lobstering with 2 miles of the Maine islands.
