<p>The Yellow Sea is the name given to the northern part of the East China Sea, which is a marginal sea of the Pacific Ocean. It is located between mainland China and the Korean Peninsula. Its name comes from the sand particles from Gobi Desert sand storms that turn the surface of the water golden yellow.
The innermost bay of the Yellow Sea is called the Bohai Sea (previously Pechihli Bay or Chihli Bay). Into it flow both the Yellow River (through Shandong province and its capital Jinan) and Hai He (through Beijing and Tianjin). Deposits of sand and silt from those rivers contribute to the sea color.
The Yellow Sea is one of four seas named in English after common color terms — the others being the Black Sea, the Red Sea and the White Sea.
The International Hydrographic Organization defines the limits of the Yellow Sea (which it also names as "Hwang Hai") as follows:
On the South. The parallel of 33°17' North from Saisyu To (Quelpart) [now known as Jeju-do] to the mainland [of China].
On the Southeast. From the Western extreme of Quelpart to Ka Nyo or West Pinnacle Island (34°13'N) in the Mengoru Group, thence to the North point of Oku To (34°22'N), to the West point of Small South</p>
