Summary of Field Work: |
The purpose of the cruise in April is to deploy (and test) a surface mooring with a real-time link to a seafloor seismometer. The October cruise is to recover the system. The exact dates are not important, but we are looking for about a 6-month deployment to test the prototype system. The cruise could be staged out of Puerto Rico- this might make the shipping and loading of gear more convenient, but would add about 4 or 5 days to each of the two cruises. We think that the Pelican or similarly sized and equipped vessel (or larger) could handle the work. We did a test deployment of the buoy system near Woods Hole using the Connecticut. |
|
Summary of Facility Requirements: |
We aren't aware of any scheduling issues at this time except for the obvious concern about hurricane season. |
|
Summary of other requirements and comments: |
We will be deploying a surface buoy (about 2.2 m diameter) weighing about 3000 pounds using the ship's crane to put it over the rail. The buoy has a mast about 10 feet high and several solar panels on its deck. The mooring will then be trailed through the A-frame. The anchor will either be free-falled or lowered on the trawl wire. The anchor weighs about 3000 pounds. A capstan will be helpful and air tuggers will also be used to handle gear on deck. The mooring is a combination of E/M cable and specially designed stretch hoses that absorb wave energy to provide a surface mooring that is always in tension. The mooring will be recovered using acoustic releases, leaving the anchor behind. We will need a crane to load the vessel and some time at the dock to wind the mooring on the winch and check out the electrical and telemetry systems. We will be installing a shore station at a local seismic site on shore to receive data from the buoy over a line of sight radio link. |
