The Beijing Anomaly is an observed seismic feature in the Earth's mantle at a depth of around 700–1400 km below Northeastern China where a high degree of seismic attenuation was discovered to exist. According to its discoverers, Jesse Lawrence (from Scripps Institute of Oceanography) and Michael Wysession (from Washington University), the Beijing Anomaly is evidence for large amounts of water contained within the mantle.
