Biography

Audrey completed her PhD in marine sedimentology at University of Bordeaux in EPOC lab with research on the morphology, architecture and establishment of a deep canyon supplied carbonate environment in northern Bahamas after participating in the CARAMBAR II cruise.

Her work focuses also on the impact of large-scale structures such as canyons on the sediment transfer and sedimentation and on the link of sedimentary features such as knickpoints, contouritic deposits and carbonate mounds with hydrodynamic conditions.

Audrey worked on the BeTar_Drill project researching bedrock suitability mapping to identify and sample rock types outcropping on the Irish continental margin towards the development of a geological map and stratigraphic model for Ireland’s deep-water territories.

She also worked on the TRIDENT project to help define an environmental baseline for Tropic Seamount against which real-time monitoring technologies can be demonstrated through key activities such as:

• Collection and standardisation of existing site characterisation data from the demonstration site.
• Data gap analysis to identify specific essential data needs to establish a baseline for the demonstration site.
• Development of a draft baseline system approach to enable calibration of potential mining and discharge impacts (appropriate, to the deep-sea mining context cognisant of International Seabed Authority recommendations).

She is now working on the Carraigh Bhaite project aiming toward bedrock mapping of the offshore Irish coastal and shelf regions through standard and semi-automated techniques.
