Because long linear cakes do not appear in nature, we repeated the experiment in a two-dimensional wave- field, so that nearly circular cakes formed in our tank. We did this experiment in the tank shown in Fig. 14-11. At the side wall of the tank we added a wedge (shown in Fig. 14-16 in plan view) so that the refrac- tion of waves around the wedge generated a two- dimensional wave field. In the experiment, we first grew a layer of grease ice 140 mm thick at an air temperature of â30 C. After the pancakes began to form on the surface, we raised the room temperature to â12 C. The pancakes were m in diameter and 10-20 mm thick. The wave period was seconds so that the wavelength was m. The wave amplitude at the paddle was 35 mm, and the separation between pancakes oscillated between 0 and 20 mm. Once the pancakes were established, we released 500 ml of Prudhoe Bay crude oil beneath the grease ice through a vertically mounted discharge tube. Figs. 14-17 and 14-18 show the development of the surface appearance of the oil over 9,160 seconds or about hours; the elapsed time from the oil dis- charge is marked on each photograph in seconds.
