Study of the 3D Euler equations using Clebsch potentials: dual mechanisms for geometric depletion (vol 31, pg R25, 2018)

After the publication of [1], it has come to the author’s attention that a class of Clebsch potentials for the Kida-Pelz flow, similar to what was derived in Appendix B of [1], has been studied in detail in [2]. We also note that there are typos in the formulas for one such example in [3], and these are corrected in [1].
