If Y is a.local Dedekind scheme and X/Y is a projective Cohen-Macaulay variety of relative dimension 1, then R(1)f(*)omega(X/Y)(1): is torsionfree if and only if X/Y is arithmetically Cohen-Macaulay for a suitable embedding in P-k(n). If X is regular then R(1)f(*)omega(X/Y)(1) is torsionfree whenever the multiplicity of the special fibre is not a multiple of the characteristic of the residue class field.
