Red sea drillings
Recent drilling in the Red Sea has shown that much of the basin is underlain by evaporites of a similar age to that of evaporites found in the Mediterranean Sea. These evaporites and their structural positions indicate that other brine areas are present - and, indeed, several others have been discovered.

The sea sled - A device for measuring bottom profiles in the surf zone
The Sea Sled is a simple, easily constructed device for obtaining relatively accurate and quick bottom profiles in the surf zone. The onshore — offshore motion associated with the passage of waves propels the sled on both its seaward traverse and the shoreward return. The device has been successfully used along the California coast.
