A family of Calabi-Yau threefolds without maximal unipotent monodromy

J.C. Rohde constructed several abstract families of Calabi-Yau threefolds without maximal unipotent monodromy. In this talk I want to describe the objects necessary to construct such a family with one dimensional base explicitly. Furthermore I explain that the variation of Hodge structures of the Calabi-Yau family is determined by the variation of Hodge structures of a family of curves and how to compute the monodromy representation and the period map in an explicit form.
