Distribution of submarine dunes over the French continental shelf - pack

The product "Distribution of the submarine dunes of the French continental shelf" contains digital vector data provided as 2D linear objects representing the crest of submarine dunes digitized from bathymetric surveys conducted by the Shom.

When several surveys have been carried out on the same area or dune, the product contains the information from all the surveys. However, the data displayed on data.shom.fr is limited to the information from the most recent survey.

Statement

This product was developed by the Shom sedimentology department during the Dunes I project (2006-2010). Its development was taken up in the Dunes II project (2013-2017), and then in the ANR project (10-IEED-0006-33) DUNES (2019-2022).

The information used for the development of this product comes from the processing of side-scan sonar data and multibeam echosounder (MBS) data surveyed, digitized manually and integrated into the product from 2006 to 2022.
