Purpose | |
Abstract | The expedition MSM46 was planned to increase the understanding of both coastal ecosystem functioning and the external forcing, that lead to long term changes within these systems. The multibeam systems performed as expected so that the Corossol-Impact-Crater, the Lake Melville and Saglek Fjord could be mapped. The sea except for a short stormy period on transit was calm. |
