Melting in a Spin

The world’s largest iceberg A23a is spinning in a Taylor column off the Antarctic coast. This poster looks at a miniature version of the problem with a fluorescein-dyed ice slab slowly melting in water. On the left, the model iceberg is melting without rotating. The melt water stays close to the base until it forms a narrow, sinking plume. In the center, the ice rotates, which moves the detachment point outward. The wider plume is turbulent compared to the narrow, non-rotating one. At higher rotation speeds (right), the plume is even wider and more turbulent, causing the fastest melting rate.
