Summary of Field Work: |
We propose to participate in the second phase of the Naval Research Laboratory’s Mixing over Rough Topography (MORT) measurements over East Flower Garden Bank on the Texas continental shelf, to be scheduled early during FY 2012, between December 2011 and January 2012. NRL requested that we bring SWIMS3, our depth-cycling towed body, to complement their observations by 1) assessing hydraulic control along lines crossing the bank in different directions, 2) estimating turbulent dissipation rates to make maps of dissipation and diapycnal diffusivity over the bank, and 3) estimating form drag produced by the rough bathymetry of the bank. By approaching within a few meters of surface and bottom, SWIMS3 offers the only way of getting the full-depth density and velocity profiles needed to make three-dimensional maps of the fields described above. Two weeks of work are proposed to coincide with NRL’s measurements comparing winter conditions with those during June. Moorings placed by NRL during June will be removed at the end of the measurements. In addition to SWIMS3, we will also operate a DX BioSonics digital acoustic backscatter system with 100 and 200 kHz transducers. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
MORT will begin in January 2011 when NRL sets moorings to last six months. When they reset the moorings the following June, NRL will also take intensive shipboard measurements. These will be followed by less intensive shipboard measurements when the moorings are recovered between December 2011 and January 2012.
We propose to participate in the second set of shipboard measurements, November 2011. |
