Scene notes:

…some fair-weather clouds in the mid-day blue sky. The shadows of sand dunes slowly creep longer on the sand. The ocean stretches away into the distance to the right. European beach-grass was introduced in the early 20th century- but its spread poses changes to the dune’s existence themselves. Its ability to live in sand is a double-edged sword for the local ecology. A largely cloudy Cirrus sky in the top third of the frame moves inland towards the right of the frame, but it has not yet fully shaded the foreground and beach beyond until late in the clip.
