Notes. For the Earth, M, R, g, Porb and Mpert are given by NASA fact sheets. The oceanic parameters H, ρs, cs and N come from Gerkema & Zimmerman (2008). For TRAPPIST-1 f, we use the values given by Wang et al. (2017) for M, R, Mpert and Porb. The surface gravity g is estimated using the definition and we use the oceanic parameters of the Earth. The ocean depth is arbitrarily set to H = 1000 km.
