Summary of Field Work: |
Deployment of instrument packages on the sea floor with instrumentation autonomous or cabled to ship for real-time data collection of current velocity profiles, seafloor roughness, and wave statistics; diver-collected data including cores and in situ seafloor erosion measurements; remotely deployed sediment profile imaging camera. |
|
Summary of Facility Requirements: |
Vessel to deploy large instrument package (NRL quadpod) and anchor boat with cable distance to package; monitor for 7-8 days, while conducting diver operations to collected data around instrument package. Vessel to deploy SPI (Sediment Profile Imager) camera while underway or drifting; divers to collect cores around experimental site. Vessel to collect Acoustic Sediment Classification System data with ship's depth sounder by traversing experimental site. |
|
Summary of other requirements and comments: |
CTD operation with Niskin bottles for collection of bottom water; scuba air compressor. Small boat for use as diver chase/diver recover vessel. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Prefer calmer winds of June-July-August for deploying instrument package and conducting diving operations. Prefer not to schedule during height of hurricane season (late August-September). Prefer not to schedule for Oct/Nov 2013 because instrumentation and funding will not be ready; prefer not to schedule for Oct/Nov 2014 because funding for field work is dedicated to period of Oct 2013-Sep 2014. |
