data set, the parameters of the approximating power function, calculated
from the remaining 13 points (Figure 8) changed:

from point B (from west to east), with cross-track average of 1 km and
along-track average of 50 m. The decreased SAR intensity in the spill area is due
to the damping of the small-scale roughness of the sea surface. The solid lines
show average radar backscatter of the sea surface west (1) and east (2) of the spill,
and in the spill area (3). The length of line 4 characterizes the width of the spill
A rough estimate of the volume of oil in the present ballast waters (
case
1
) was obtained by assuming that the oil discharge rate between points
A
and
B
was constant. In such a case, the width of the spill at point
B
at 192
min will be the same as near point
A
on the SAR image (Figure 1a). Since
