Sabine Christiansen coordinates the R&D project “Ecological Safeguards for Deep Seabed Mining”, 2015-2017, which is financed by the Umweltbundesamt, UBA. The project is part of the suite of “Ocean Governance” projects, led by Sebastian Unger. Sabine studied biology and has a doctoral degree in biological oceanography and polar ecology. In 2015 she was a fellow at IASS with a project investigating the potential sustainability of deep seabed mining. Until 2015, Sabine worked as a consultant at the science-policy interface in the field of marine conservation in Germany, Europe (EU), in the OSPAR Maritime Area, within and beyond national jurisdiction, a.o. towards the designation and appropriate management of networks of marine protected areas, in particular in deep water, conservation measures for deepwater habitats such as hydrothermal vents and seamounts - both habitats now threatened by deep seabed mining. Since 2009, deep seabed mining has come into the focus of her activities as a potentially threatening activity, in particular with respect to the development of the international framework conditions for minimising environmental harm.
