Oceanography Figure A. 7 Contrast-stretched sequence of MSS-6 data off Miami Beach,Florida (ERTS ID 1026-15230), observed on 18 August 1972. Sequence shows the effect of varying the DN range and n in the contrast equation, a) Upper left: Raw data, positive print, b) Upper middle: ;DN<15; n=l. c) Upper right: 7^DN<15; n=3. d) Lower left: 7<DN<11; n=l. e) Lower middle: 9<DN<13; n=l. f) Lower right: MSS-6 minus MSS-7, then 5*DN£l3; n=3.

Note that using powers of n brings out water details (cf. b & d). Water details in e are less distinct than in b which uses the statistically determined limits. Sea state only is observable in MSS-7, so ,MSS-6-MSS-7 should minimize the surface contribution as is shown in f. Horizontal distance across each image is 45 km. 438.
