Abstracts:  Katleen Robert (NOC) - Mapping of Complex Structures:  Novel imaging of deep-sea vertical habitats

Vertical and overhanging walls in complex deep-sea environments can harbour high biodiversity and host vulnerable marine ecosystems, to which they provide natural protection from certain human activities (e.g. trawling) as a result of their geometry.  As such, it is important to understand their ecology, but traditional ship-board multibeam echosounders cannot adequately replicate the complete 3D structure of vertical habitats, and towed video systems are challenging to operate in these rugged environments.  This presentation will look at novel photogrammetry techniques (structure from motion, SfM) which allow the creation of 3D representations of video transects acquired with remotely operated vehicles.  With these reconstructions, it becomes possible to interact in 3D with extensive sections of video footage which cannot otherwise be visualized in their entire context.

The Innovation Centre can be reached via the workshops/stores corridor on the ground floor, and a sign to the Hub is about 100 m down that corridor on the right. Go up the stairs and through the door and turn right. Note that the access door to the Innovation Centre Hub is security-locked, but we will ensure it is monitored so attendees can be let in promptly. 

We only have seating capacity of about 30 in the Innovation Centre Hub, so be aware that if we exceed this it will be standing room only. There will be opportunities for informal discussions over doughnuts in the Innovation Centre Hub before and after the talks.
