_D_e_s_c_r_i_p_t_i_o_n:

     The 'tuna' data frame has 64 rows and 1 columns.  

     The data come from an aerial line transect survey of Southern
     Bluefin Tuna in the Great Australian Bight. An aircraft with two
     spotters on board flies randomly allocated line transects. Each
     school of tuna sighted is counted and its perpendicular distance
     from the transect measured.  The survey was conducted in summer
     when tuna tend to stay on the surface.
