Summary of Field Work: |
We plan to investigate the seafloor bathymetry, acoustic imagery (reflectivity) and shallow sub-bottom geometry of the upper part of the slope of the Little Bahamas Bank, North of Gran Bahama Island, at a bathymetry extending between 30 and 400 m water depth.
The objective is to identify sedimentary and erosion structures potentially allowing to transfer sediment from the carbonate bank to the upper carbonate slope.
We also collect a few (< 10) short kullenberg sediment cores (grab if diagenesis is too important) to get the sedimentological groundtruth. |
|
Summary of Facility Requirements: |
Very High resolution Seismic (Chirp subbottom profiler)
Kullenberg coring facilities (or sediment grab) |
|
Summary of other requirements and comments: |
Multibeam echosounder system hired at Seafloor System Company including material to calibrate the sound velocity |

Short Description of Op Area
for use in schedules: |
LBB, Bahamas |
| Description of Op Area: |
We are going to survey a rectangle box with simultaneously multibeam and chirp data acquisition (7 days). Once this is done, we will define between 5 to 10 coring locations (1.5 day for coring) using the newly collected bathymetry and HR seismic data.
Bathymetry will be always between 30 and 400 m. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Multibeam will be hired to "acoustic system" company. It will be set up on a perch fixed in the moon pool of the boat
Seismic is the classical high-resolution seismic (3.5 kHz) gear which is on the Walton Smith boat
