Dataset for 'Meteorological Conditions Influence the Migration of a Marine Dune Field in the Southern North Sea'

This dataset complements the paper 'Meteorological Conditions Influence the Migration of a Marine Dune Field in the Southern North Sea' accepted for publication in Journal of Geophysical Research - Earth Surface.

This dataset contains Digital Terrain Maps (DTMs) of specific areas offshore from Dunkirk, on the northern coast of France, opening to the Southern Bight of the North Sea. These areas host marine dunes (sand waves) that have been numerically investigated in this research to identify the parameters influencing their migration. The openTELEMAC system (version v8p4) can be downloaded from https://opentelemac.org/. The model development, calibration and validation is described in Durand (2024).

The site-specific data collected by France Energies Marines (2021) are currently proprietary. To protect these data, DTMs of bathymetric changes are provided, calculated as the difference in metres between the final and initial seabed levels. Negative values indicate lowering of the seabed (erosion) and positive values indicate rising (accretion).

The initial and final periods are:

S1: 17-Nov-2019

S2: 17-Mar-2020

S5: 5-Dec-2020

The DTMs are provided for two areas (refer to paper for locations):

Tile #1

Tile #3

Included in the dataset are observations, Case I model output (without wind and atmospheric pressure), and Case II model output (with wind and atmospheric pressure).
