Figure 2- — Bottom bounce data and temperature profiles for the December la-el. May (f-j). and September (k-ol surveys. The 

 distribution of schools mean depth (a, f. k), the cumulative distribution of mean school depths (b, g, 1), and the thermal profile (c, h, m) 

 are given versus depth with the scale on the left. The distribution of school thickness id, i. nt and the cumulative distribution function 

 for thickness (e, j, o) are associated with the scale on the right.
