AB  - Geophysical multi-source electromagnetic modelling is usually performed solving a linear system of equations for each right-hand side. This approach can be prohibitively expensive when the system of equations has a large number of degrees of fredom and sources. We present an alternative method for multi-source forward modelling of marine CSEM data. For the discretization of the electric field equation we use edge finite elements which naturally satisfy the material interface conditions for the electric field and avoid the presence of spurious modes in the solution. For solving the system of equations we use the software package MUMPS to factorize the system of equations. A solution for each right-hand side is then obtained using the same factorization.
