Sand ripples displacement map in the East/West direction (Eastward positive)
Sand ripples displacement map in the North/South direction (Northward positive)
All dunes in the area 2 footprint are subject to ripples migration. The direction of the ripple migration is mostly North/South, although strong uncorrected satellite jitter in the East/west direction prevent from measuring the eastward component of the ripples migration. On average ripples migration of 1.5-2 meters in the 3 years, 1 month time frame is observed.

-2.7 m 0.5-2.5 m 1.0
Sand ripples displacement map in the East/West direction (Eastward positive)
Sand ripples displacement map in the North/South direction (Northward positive)
All dunes are subject to ripples migration; migration amplitude of more than 2 meters in the 3 years, 3 months time frame is observed on several dunes.

Orientation of the ripples migration over the 3 years, 3 months period
Orientation is in accordance with dune shape and evolves from a South direction to a South-East direction the further we go south on the dune field
