Oceanography Figure Contrast-stretched (4<DN<11: n=l) negative MSS-5 image of Onslow Bay, North Carolina (ERTS ID 1205-15153), observed on 13 February 1973. Complex patterns of turbidity do not appear to be well correlated with the bottom topography. The white pixels near the coast are an artifact of the contrast stretch routine, wherein the NOAA computer assigns a negative zero to the upper cutoff value (DN=11 in this case).

Oceanography Figure Contrast-stretched (4<DN<11: n=l) negative MSS-5 image of Onslow Bay, North Carolina (ERTS ID 1205-15153), observed on 13 February 1973. Complex patterns of turbidity do not appear to be well correlated with the bottom topography. The white pixels near the coast are an artifact of the contrast stretch routine, wherein the NOAA computer assigns a negative zero to the upper cutoff value (DN=11 in this case). When the negative zero is reformed onto the digital to analog tape, it inadvertently becomes a maximum value which appears on the image as a white pixel. The scene appears gray because black (DN-11) and white (DN=11) values are intermixed. This does not appear in images with n^2 and has been corrected for. Horizontal scale distance across the image is 135 km. 442.
