GEOMAR is one of 19 Helmholtz Centres in Germany that undertake research in any aspect of science. GEOMAR is one of three marine centres within Helmholtz, mainly working in the open ocean, but in some cases also close to shore. GEOMAR covers many aspects of marine research, ranging from physical oceanography, marine meteorology, geology and geophysics, benthic and pelagic biogeochemistry to biology and microbiology. In addition to its scientific tasks, GEOMAR operates large scale equipment, among them several AUVs, ROVs and smaller systems like mobile multibeam systems, a large number of lander-based and seafloor deployable camera systems and many others. GEOMAR's DeepSea Monitoring group, which has experience in numerous projects in the issue of munitions in the sea, is also involved in the projects CONMAR and ProBaNNt.
