GEOMAR is structured into four research divisions:

Ocean circulation and climate dynamics: This division, led by Katja Matthes and
Mojib Latif
Mojib Latif (born 29 September 1954) is a German meteorologist and oceanographer of Pakistani descent. Latif graduated with a Diplom in meteorology in 1983. He took a position as scientist at the Max Planck Institute for Meteorology in 1985. ...

of marine bio-resources." It is important to understand how much stress a given ecosystem can absorb before structural shifts occur. When a shift does occur, it is necessary to understand how this will impact the ecosystem populations and the degree to which the shift can be reversed. Structural shifts can result in invasions by harmful organisms, species collapse and a radical reconfiguring of the
biogeochemical cycles. Traditional approaches group species broadly into size classes and
