Given an elliptic fibration f: X→ S over the spectrum of a complete discrete valuation ring with algebraically closed residue field, we use a Hochschild–Serre spectral sequence to express the torsion in R 1 f⁎ O X as the first group cohomology H 1 (G, H 0 (S′, O S′)). Here, G is the Galois group of the maximal extension K′/K such that the normalization of X× S S′ induces an étale covering of X, where S′ is the normalization of S in K′. The case where S is a Dedekind scheme is easily reduced to the local case. Moreover, we generalize to higher-dimensional fibrations.
