Within ASMASYS, a transdisciplinary evaluation framework for marine CDR options will be developed as the base for a uniform evaluation of the different marine CDR options, and as a nucleus for further homogenization with the evaluation of CDR options on land. Strong emphasis will be put on non-natural science aspects, including criteria addressing legal, social, and ethical aspects, as well as political framing and policy-inherent internal mechanisms. Current gaps in the evaluation chain will be analysed. ASMASYS will also address the current hurdles with respect to the permission of demonstration projects involving field studies, which are an indispensable prerequisite for full scale technical application. In particular, sustainability will be a strong component of the assessment framework, using the UN Sustainable Development Goals (SDGs) as criteria. 

The current knowledge on some marine CDR-options not covered by the joint projects of the DAM mission will be compiled, including recent progress and development in other international initiatives. Knowledge of methods addressed within the research mission will be requested from the funded projects of the FM and compiled with regard to the assessment framework. The marine CDR options under consideration in the mission will be assessed in detail using the developed assessment framework. Based on this, an interim synthesis will be provided, and potential new directions for the 2nd funding phase of the Research Mission will be identified. 

During the entire course of ASMASYS, strong interaction and exchange is foreseen with all projects of the mission, currently active international research activities, stakeholders, and the synthesis project of the CDR-funding-line. The transfer component within ASMASYS will assure involvement of specialists and stakeholders during the development of the evaluation framework, and provide tailored dissemination products for the scientific community, decision makers, and the public. Special attention will be paid to ensure that the work results and products of ASMASYS are of relevance for the national climate strategy of Germany.  

IOW coordinates the collaborative project ASMASYS, including organization of the "Think Tank”, promoting the transdisciplinary work within and outside the project, and communication and integration with the entire RM. It develops the natural science criteria for marine CDR options, with particular emphasis on potential risks, co-benefits, and monitoring,  and organizes and leads the work to develop the core assessment framework for marine CDR options. IOW (as a strong co-partner of GEOMAR) is compiling the state of knowledge by the end of the project for both marine CDR options addressed by the RM and those not considered. IOW is leading the preparation of the interim synthesis and recommendations for future research
