Fig. 8

Sequence of georectified images, ordered chronologically as (a–d), showing the sea surface signature of naturally-occurring underwater waves interacting with the wharf. Photos taken on 27 September 2023. See Fig. 7 for the original field of view. For scale, the schematic ship depicted in the lower right corner of each panel has the size of the MV Jaeger Arrow, \(171~\textrm{m} \times 25~\textrm{m}\). The red dot identifies the position of the thermistor chain. The direction of the underwater waves, illustrated by arrows, was determined from the sequence of consecutive images. The white axis in panel (b) is labeled in meters. A satellite image of the Grande-Anse terminal, identical to that in Fig 4, is overlaid on top of the georectified images.
