Two views of rippled dunes from Sandy Tongue dive site


Two views of the rippled dunes at the Sandy Tongue dive site. These sands are a hundred percent biogenic, comprised of shells and tests of small organisms, such as foraminifera, mollusks, and echinoderm spines. Dunes at this location measured 3 to 4.5 m high. Dunes at the Coral Mounds dive site were as high as 15 m.
