Title: Overlay composite image

Description: Composite of figures 2a and 2c to 2e. The time span between the white (figure 2a) and yellow (figure 2c) position of the iceberg was 48 hours, however, and only 15 hours between yellow and red (figure 2d). So, the berg gained considerable velocity (from about 0.07 kts to 0.4 kts).

The latter value could also be calculated for the next 24 hours, when the iceberg drifted from the red to the blue position (figure 2e). The anticlockwise rotation of the iceberg from the yellow towards the blue position is very clear.
