Seawater intrusion was observed in China’s coastal aquifers as early as 1960s. At present, it covers an area of more than 2,000 km2 in China. In 2002, the seawater intrusion area was increased to 1773.6 km2 in Shandong Province, China, and it is continuing to extend in the coastal area of...
- TIDAL FLATS. Semeniuk, V. // Encyclopedia of Coastal Science;2005, p965
The article provides information on tidal flats. Tidal flats are described as low-gradient tidally inundated coastal surfaces. They are defined as extensive, nearly horizontal, marshy or barren tracts of land alternately covered and uncovered by the tide. They are made up of unconsolidated...

Anoxic Halic Bay sediments have been extremely polluted with petroleum hydrocarbons, and N and P are limited in the sediment porewaters for biological activity. These raised the question that hydrocarbon degradation activity of Halic Bay sediments can be increased by N-P amendment under...

The article reports on the discovery of Oceanic Anoxic Event 2 (OAE2) in Romania. The isotopic and paleobiological studies in the region point out to the presence of OAE2. A positive excursion of the d13C was recorded in the sediments encompassing the Cenomanian/Turonian boundary. This interval...
