Myanmar - December 17th, 2011

Tides in the Gulf of Martaban range between 4-7m, and are highest to the west, by Elephant Point. During spring tide, when the tidal range is around 6.6 m, the turbid zone covers an area of more than 45,000 sq km making it one of the largest perennially turbid zones of the world’s oceans. During neap tide, with tidal range of 2.98 m, the highly turbid zone coverage drops to 15,000 sq km.  Here, sediments from the Salween Sittaung and Yangon Rivers.

Visible by the western edge of the gulf is the Irrawaddy Delta (or Ayeyarwady Delta), which lies in the Ayeyarwady Region, the lowest expanse of land in Myanmar. It fans out from the limit of tidal influence at Myan Aung to the Bay of Bengal and Andaman Sea, 290 km to the south at the mouth of the Ayeyarwady River.
