Since its foundation, the research center MARUM – Center for Marine Environmental Sciences (hereafter referred to as MARUM) has developed into an internationally recognized center for marine research anchored at the University of Bremen. MARUM’s position within the University of Bremen was considerably strengthened in 2012 when MARUM became the first and only Research Faculty of the University of Bremen. Through MARUM, the University of Bremen closely collaborates with the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research in Bremerhaven (AWI), the Max Planck Institute for Marine Microbiology in Bremen (MPI), the Senckenberg Institute by the Sea in Wilhelmshaven (SGN), the Leibniz Centre for Tropical Marine Research in Bremen (ZMT), the University of Oldenburg, and the private Jacobs University in Bremen.
