Submarine landslides and seabed stability

Challenge ID

C-CORE_OFF2.2

Title

Submarine landslides and seabed stability

Challenge originator:

 

General Description

 

What data/products do you use?

Sidescan, multibeam sonar bathymetry maps, sub-surface data if available

When do you use this kind of dataset?

During seismic surveys to determine susceptibility of substrate to seismic activities and gain information on substrate stability

 

During exploration and development to help determine of anchor placement or location of production platform

What are your actual limitations and do you have a work around? 

This data is currently not available unless the area has seen recent multibeam mapping.

 

Current data acquisition is vessel based and thus expensive and time consuming

Needs and expectations on EO data

Not sure, EO capabilities can address this as it requires penetration to ocean floor

 

Unclear - require sub-sediment penetration into ocean floor
