The sandy beach fauna of Egypt - ScienceDirect

1989-9-1  Intertidal sand beaches along the Mediterranean and Gulf of Suez Egyptian coast were examined in 1985. Mediterranean beaches were characterized by few species, low density, and no Lessepsian migrants. A total of 78 species were collected from sandy beaches in the Gulf of Suez with species richness increasing with decreasing exposure to wave action.

It depends on if 1-2% accuracy is sufficient. 1-2% is 10-20kg/m3 for water. Vibrating fork will give you 1kg/m3 and vibrating tube will get you 0.1-0.2kg/m3.

2008-5-27  Changes to sand compactness caused by vehicles were influenced by sand moisture. Vehicles generally lowered compactness when driven in dry sand, which had a water content of less than 18%. Conversely, vehicles driven in the lower intertidal zone over more saturated sands (>18% moisture) generally hardened the sediment matrix.
