Mysterious singing sands d iscovered along China’s Hainan coast

CHINESE scientists have discovered an area of “singing sands” on the tropical island province of Hainan, the first time the strange auditory phenomenon has been identified on the country'’s coastline.

Singing sands – also known as rattling sands, whistling sands or musical sands – consist of sandy areas of desert or coastline that naturally produce sounds in the wind due to a combination of physical characteristics, including the size and composition of the grains.

According to the Northwest Institute of Eco-Environment and Resources (NIEER) under the Chinese Academy of Sciences, the discovery marks the first time that an area of Chinese coastline has displayed the phenomenon, and enhances the province’s tourism potential.

“The discovery of the magical natural phenomenon fills the gap of coastal singing sands in China. It will provide technical support to the development and protection of tourism resources in Hainan,” said Qu Jianjun, an NIEER researcher and leader of the team that made the discovery.

Singing sands can be found at multiple inland sites within China, including the renowned Singing-sand Mountain, located near the Mogao Grottoes in the oasis city of Dunhuang, in north-west China’s Gansu

province. Such sites provide a draw to visitors, keen to experience the strange phenomenon.

“The distribution of coastal singing sands is regarded as a reflection of quality beaches. It has long been assumed that there are no coastal singing sands in China, and our latest study provides a new answer,” said Qu.

The NIEER team discovered multiple singing-sand sites along the coasts of Clearwater Bay, Shenzhou Peninsula and other areas in Hainan.

The study shows that the unique geomorphology and wave-breaking dynamics of these bays have shaped the well-sorted coastal sands in terms of grain size.

The scientists investigated the characteristics of the coastal singing sands, such as the mineral composition, particle size, surface structure and acoustic characteristics, and compared them with those of singing sands in a desert region.

Their study shows that the surface of the coastal sands has typical V-shaped craters formed by underwater mechanical etching, and deep dissolution craters formed by chemical etching. |
