Abstract:
 Chiral edge states in the quantum Hall effect are protected by a chiral anomaly, which physically is spectral flow through a filled Dirac sea. I will investigate whether chiral planetary edge states, namely the Kelvin wave, possess a similar level of protection to quantum Hall edge states. An important conclusion will be that, unlike the quantum Hall case, the ocean does not have a sea. My findings may – but probably do not – have relevance to understanding the El Niño-Southern Oscillation.
