Deadline: 21. August 2020 "We are looking for motivated individuals from diverse backgrounds to contribute to multi-stakeholder virtual working groups in Fall 2020. These working groups will be oriented around key ocean-based CDR pathways, as well as cross-cutting issues that affect all ocean-based CDR pathways. If you are interested in participating in one or more working groups, please sign up with the survey below by August 21." LINK

"Yet, their technical design characteristics, financial cost of deployment, and emissions have yet to be studied in detail. Therefore, these topics are examined in this two- part study. This first part outlines a set of injection scenarios and proposes a detailed, feasible aircraft design. Part 2 considers the resulting financial cost and equivalent CO2 emissions spanned by the scenarios and aircraft. " LINK
