## Scoping Study Discussion

### Functional Requirements

Revisitation shows that much is covered here, but Dave updated some for us:

* Duration: 24 hours cycle (i.e. 16 operating, 8 turnaround)
* Survey Area
  * Current surveys are 0.2 m/s for 8 hours to cover a 100m x 100m box
* 6KM depth rating
* Primary Products:
  * Multibeam soundings & water column data
  * Lidar (360 slightly obstructed)
  * Images
