Vegetation Index Near Irrawaddy Delta, Myanmar

16.5N 97.0E

February 19th, 2012 Category: Vegetation Index

Myanmar - December 30th, 2011

This FAPAR image shows the vegetation index of southern Malaysia. The country has 1,930 kilometres (1,200 mi) of contiguous coastline along the Bay of Bengal and Andaman Sea to the southwest and the south, which forms one quarter of its total perimeter.

Myanmar has mountain chains that divide its three river systems, and fertile plains exist in the valleys between the mountain chains. Here, the Irrawaddy River, the country’s longest river, nearly 2,170 kilometres (1,348 mi) long, can be seen flowing into the Gulf of Martaban. In this image, the vegetation index is highest (rusty red) near the coast to the northwest of the Irrawaddy Delta. It is generally good (green) to the east of the delta. By the delta itself, and north of the Gulf of Martaban, the index is mixed, including some areas of low (yellow) photosynthetic activity.

Sediments in Gulf of Martaban and by Irrawaddy Delta, Myanmar

16.5N 97.0E

February 7th, 2012 Category: Rivers, Sediments

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.

Sediments in Irrawaddy River Delta and Gulf of Martaban, Myanmar

November 16th, 2011 Category: Rivers, Sediments

Myanmar - November 8th, 2011

In southern Myanmar, sediments pour forth from the delta of the Irrawaddy River (left) and from the Gulf of Martaban (right), into the Andaman Sea. The delta begins about 93 kilometres (58 mi) above Hinthada (Henzada) and about 290 kilometres (180 mi) from its curved base, which faces the Andaman Sea.

The westernmost distributary of the delta is the Pathein (Bassein) River, while the easternmost stream is the Yangon River, on the left bank of which stands Myanmar’s capital city, Yangon (Rangoon).  The relief of the delta’s landscape is low but not flat.[20] The soils consist of fine silt, which is replenished continuously by fertile alluvium carried downstream by the river.

Sediments in Gulf of Martaban and Channels of Irrawaddy River, Myanmar

20.7N 72.0E

February 26th, 2011 Category: Rivers, Sediments

Myanmar - February 11th, 2011

Tan sediments color the waters of the Gulf of Martaban, in southern Myanmar. These sediments spill forth mainly from the Salween Sittaung and Yangon Rivers.

Although the gulf often appears completely opaque tan, in this image the sediment load is lighter. The lower part of the gulf thus appears greenish in color, while the upper part shows tan streaks from the movement of the silt (best observed in full image).

Sediments can also be observed at the delta of the Irrawaddy River (or Ayeyarwady River), west of the gulf. Click here for a detailed look at the channels of the Irrawaddy.

Sediments in Irrawaddy Delta and Haze from Fires in China Over Myanmar

Myanmar - November 5th, 2010

The Irrawaddy (Ayeyarwady) River flows southwards across Myanmar before empyting indo the Andaman Sea. The bay into which it flows is tan from the heavy load of sediments carried by the river.

Multiple ridges of mountains can be seen in the right half of the thumbnail, and in the full image the Himalayas can be seen, capped with snow, at the top. Also visible along the right side of the image (best observed in the full version) is a light veil of smoke carried westward from fires that were burning in Eastern China.
