Ocean iron fertilization is currently discussed as a potential measure to mitigate climate change by enhancing oceanic CO2 uptake. Its mitigation potential is not yet well explored, and carbon offsets generated through iron fertilization activities could currently not be traded on regulated...

Diminishing emission budgets and increasing risks of catastrophic damages from climate change require analyses of rapid response options including geoengineering options such as ocean iron fertilization (OIF). To decide whether or not OIF might be such an option an assessment of its potential as...

Despite large uncertainties in the fertilization efficiency, natural iron fertilization studies and some of the purposeful iron enrichment studies have demonstrated that Southern Ocean iron fertilization can lead to a significant export of carbon from the sea surface to the ocean interior. From...

To stay within the 2êC temperature increase target for climate change calls for ambitious emission reduction targets already for the 2012-2020 compliance period. Cost-efficiency is a crucial criterion for the enforcement of such ambitious targets, requiring analyses of all possible abatement...

We investigate the socially optimal anthropogenic intervention into the global carbon cycle. The limiting factor for this intervention is the accumulation of carbon in the atmosphere, which causes global warming. We apply a simplified two-box model to incorporate aspects of the global carbon...

In the presence of rising carbon concentrations more attention should be given to the role of the oceans as a sink for atmospheric carbon. We do so by setting up a simple dynamic global carbon cycle model with two reservoirs containing atmosphere and two ocean layers. The net flux between these...

Angesichts stark wachsender Nachfrage nach Rohstoffen, insbesondere vonseiten der aufstrebenden Schwellenländer und entsprechend steigender Rohstoffpreise, richtet sich der Blick zunehmend auf die Tiefsee als enorme noch weitgehend unerschlossene Quelle reichhaltiger Rohstoffvorkommen. Der...
