Hydrophone placed about 6 inches below the sand at the shore line. The rustling is the sand moving across the microphone and you can also hear the rumble of the wind above ground.

Holme Dunes – July 2017
I buried a hydrophone about 6 inches into a sand dune below some of the grass. The result, on a very windy day in North Norfolk, was this amazing sound. It sounds more like bamboo rattling together with the occasional whoosh of wind as it raced across the sand above.
