ages. More detailed experiment descriptions and analyses concerning the
ERS-1 data acquired during the experiment can be found in Bern et al.
(1992b).
Figure 1 shows how the spills (areas of reduced backscatter on SAR im-
age) drifted during the observation period according to the SAR images.
As inferred from the figure the drift of the spills was complicated and was
affected by wind, waves and currents (for details see Bern et al. 1992b).
Table 1 summarises the survey parameters, wind/wave conditions, age of
oil spills and measured damping ratios.

The evolution of two oil spills deployed during the DOSE'91 Experiment.
The numbers denote the spill contours delineated from the SAR images:
1 - ERS-1, 22.08, first spill, spill age 16 hrs
2 - Almaz-1, 22.08, first spill, spill age 22 hrs
3 - Almaz-1, 23.08, first spill, spill age 40 hrs
4 - ERS-1, Almaz-1, 25.08, first spill, spill age 88 hrs
5 - ERS-1, Almaz-1, 25.08, second spill, spill age 18 hrs
6 - Almaz-1, 27.08, second spill, spill age 72 hrs
