Summary of Field Work: |
We plan to test an ocean acoustics system that consists of a seafloor receiver called DOGS (manufactured by DBV Technology) that needs to be dropped and recovered to the ocean floor, and whose location is being surveyed by a sound source integrated with a GPS system mounted on a Datamaran (manufactured by Autonomous Marine Systems) of the Mark-8 type. We lower the DOGS to the seafloor, deploy the Mark-8 and conduct two orthogonal 6-hour transects with it. Subsequently we recover the units. We estimate the whole operation could take place in about 20 hours. |
|
Summary of Facility Requirements: |
The R/V Atlantic Explorer, as we recall from having used her before, will have all the necessary equipment. |
|
Summary of other requirements and comments: |
We will work with the Captain and the BATS PI to set up a feasible experiment. But the idea is that it can be a small add-on to an existing BATS cruise. We are trying taking advantage of deep water doing something that we have already done once, in shallow water (Boston Harbor)... |

Dates to Avoid: |
We can be flexible but the April 20th BATS cruise appears ideal. |

Other Ship(s): |
We will work with the Captain and the BATS PI to set up a feasible experiment from the Atlantic Explorer. In prior discussions we settled on the need to request one additional science day. My calculation below is a guesstimate for the total including the regular BATS cruise. |

Explanation of Science Party Requirements and Technician Requirements |
Bud Vincent from DBV Technologies/URI will be the operational lead. In our prior fieldwork to date, including on the Atlantic Explorer, we have had the assistance of some 2 on-board technicians, and we expect to be able to rely on them this time as well. Again, we will be glad to discuss the detailed operational plan, which is straightforward, offline. |
