Summary of Field Work: |
This project will consist of two cruises to EPR 9N to study the transition in microbial community and mineralogy of hydrothermal vents during the first year post-venting. We will sample multiple active hydrothermal vents, splitting samples into three sections. One will be recovered on the same dive for analysis, and two will be left on a platform (we plan on using an elevator) to incubate for a few weeks (t1, collected during same cruise) and a year (t2, collected during second cruise). For the first cruise, we are requesting 12 dive days, and 6 for the second. The proposed field sites are Bio9/P vent area and Biovent area. |
|
Summary of Facility Requirements: |
we will need NDSF resources for this project. for two cruises, either HOV Alvin or ROV Jason II is requested, either one will be sufficient for the work proposed. we will also likely need two elevators to be left on the seafloor between the two cruises. funds ($8000, determined by discussion with Dan Fornari) were requested for this extended use of the elevators in the NSF budget and do not need to be considered here. it is likely that we will use one or two additional elevators for normal shuttling of samples/supplies to and from the seafloor during these cruises. we will also need the Titanium Major samples. |

Explanation of Science Party Requirements and Technician Requirements |
From Sylvan group, Sylvan (PI) will be going, with two grad students. From Brandy Toner's lab, Toner (PI) will go and will bring one grad student. From Meg Tivey's group, Tiver (PI) will go. One additional student (as volunteer) is likely from one of the three groups, but not yet specified. |

Alvin would be equally acceptable for the work, but Atlantis will be in refit during requested cruise dates, so ROV Jason is necessary for the proposed work - rock samples and experiments will be collected from the seafloor and from hydrothermal vents with precision, therefore an HOV or ROV is necessary. we will also map off-axis sites to look for extinct vent fields that have moved off axis or currently active off-axis sites. at least one such site was sampled in 2019 and will be revisited. |
