Summary of Field Work: |
We propose to visit the vents located on the EPR at 9°N during two separate cruises. Additionally, PI Mullineaux has NSF-OCE funding that includes two cruises to EPR at 9°N, one in December 2019 and another requested for early 2021. We will leverage Mullineaux’s 2019 to deploy the Established biofilm experiment only; because this is a cruise of opportunity, we will only have time to deploy settlement plates without recovery during the same cruise and to run some pilot shipboard settlement experiments. We request two subsequent longer cruises: one in March 2021 followed by another 2-8 months later (requested in November 2021 to allow time for initial statistical modeling in between cruises). Our requested two cruises will each be 30 days in length to accommodate the aging experiment and the shipboard experiments and transit to the site (4 days each way), and to include 2 weather days. During each cruise, we will use DSV Alvin (or ROV Jason) for deployment and recovery of experimental colonization sandwiches and for co-located biofilm, in situ geochemistry, larval flux, and site characterization. The dive series will be complemented with planktonic larval collections and shipboard larval settlement experiments. This will allow us to test hypotheses generated by the previous shipboard experiments and via the initial statistical modeling during the second cruise. Part of the dive time on the first cruise will be devoted to capture footage to produce a science-in-action documentary film with the involvement of undergraduate students as part of Rutgers University filmmaking program (section 6.1). Finally, should our current proposal be funded, we will request to pair our cruise 1 with Mullineaux’s next funded cruise requested in early 2021, which will maximize efficient use of ship time and funding. |

Summary of Facility Requirements: |
R/V Atlantis; DSV Alvin (ROV Jason can be substituted if necessary due to scheduling) |
|
Summary of other requirements and comments: |
PI Mullineaux has recently been recommended for NSF-OCE funding that includes two cruises to EPR at 9°N, during December 2019 and requested for early 2021. Should our current proposal be funded, we request to pair our cruises 1 with Mullineaux’s, which
will maximize efficient use of ship time and reduce the travel and personnel
costs. |
