This is the first dedicated assessment of the wide range of proposed marine geoengineering approaches. It catalogues 27 approaches (including variations of approaches) and details 8 illustrative examples from the categories spanning Carbon Dioxide Removal (CDR), Albedo Modification (AM), and hybrid (i.e., for purposes extending beyond CDR or AM) technologies. • The information available on proposed marine geoengineering techniques varies widely, ranging from the promotion of initial concepts on web sites to theoretical examinations of potential efficacy and risks in the peer-reviewed literature, supported by some basic descriptions of matching technology. Techniques have been proposed by scientists and by the private sector. • Descriptions are provided for >20 techniques and are structured to include: approach/rationale; underlying principle(s); extent of knowledge; evidence of concept; proposed deployment zone(s); potential scale of use; duration of deployment; .....
