(a) Northeast Pacific along 152° W (i) Arrhenius activation energy plot and (ii) Eyring–Gibbs free energy of activation equation plot. Data are from table 2 in Sonnerup et al. [22]. (b) Northeast Pacific 20° N, 152° W (i) Arrhenius activation energy plot and (ii) Eyring–Gibbs free energy of activation equation plot. Data are from fig. 9 (gradient calculation) in Sonnerup et al. [22]. (c) Northeast Pacific 20° N, 152° W (i) Arrhenius activation energy plot and (ii) Eyring–Gibbs free energy of activation equation plot. Data are from fig. 9 (path calculation) in Sonnerup et al. [22]. (Online version in colour.)
