Snow-Capped Baekdu Mountain, China and North Korea

China and Korea – May 23rd, 2013

Baekdu Mountain, also known in China as Changbai Mountain and Baitou Mountain, is an active volcanic mountain on the border between North Korea and China. It is visible here by way of its snow-capped peak, near the image center.

At 2,744 m (9,003 ft), it is the highest mountain of the Changbai mountain range to the north and Baekdudaegan mountain range to the south. It is also the highest mountain in the Korean Peninsula and in northeastern China. A large crater lake, called Heaven Lake, is in the caldera atop the mountain.

Airborne dust can be seen along the northern and southern rims of the Taklamakan Desert (above). Across the Himalayas to the southwest, haze, possibly a combination of dust and smoke, can be seen as well as over northern Pakistan and India (lower left quadrant).

Vastness of Tibetan Plateau; Cities of Northern India

India – May 19th, 2013

The populated cities of northern India (below) stand in contrast to the seemingly vacant terrain of the Tibetan Plateau (above), a vast, elevated plateau covering most of the Tibet Autonomous Region and Qinghai Province in western China, as well as part of Ladakh in Jammu and Kashmir.

It stretches approximately 1,000 kilometres (620 mi) north to south and 2,500 kilometres (1,600 mi) east to west. With an average elevation exceeding 4,500 metres (14,800 ft), the Tibetan Plateau is sometimes called “the Roof of the World” and is the world’s highest and largest plateau, with an area of 2,500,000 square kilometres (970,000 sq mi).

The Tibetan Plateau contains the world’s third-largest store of ice. Experts have warned that the recent fast pace of melting and warmer temperatures will be good for agriculture and tourism in the short term; but issued a strong warning for the future: temperatures are rising four times faster than elsewhere in China, and the Tibetan glaciers are retreating at a higher speed than in any other part of the world. First, this will cause lakes to expand and bring floods and mudflows. In the long run, the glaciers are vital lifelines for Asian rivers, including the Indus and the Ganges. Once they vanish, water supplies in those regions will be in peril.

Smoke from Wildfires in China and Russia

China – May 6th, 2013

A hazy veil hangs over the land around the Bohai Sea, in northeastern China and Korea. The haze may be caused by hundreds of wildfires burning to the north, in both China and Russia. In the full image, the exact locations of these fires are designated by red markers, and smoke plumes can be seen as well.

Changes in the Coastline of the Bohai Gulf, China – April 29th, 2013

China – April 29th, 2013

The evolution of a coastline reflects the influence of geology, rivers, climate, tides and sea level changes. Bohai Gulf, visible here with a strong presence of sediments, is the core region of the China Bohai Bay economic circle, so the research of coastline changes and the driving forces is of great importance for socio-economic sustainable development and regional environmental protection.

By analyzing spatial and temporal coastline changes and the driving forces behind them, scientists have shown a dramatic increase in the proportion of artificial coastlines over the past thirty years, as well as increases in coastline length.

As a result of coastline changes, land area increased by 760 square kilometers during 1979-1989, 424 square kilometers during 1989-2000 and 608 square kilometers during 2000-2010. Due to coastal erosion, however, there were 66.2, 77.5 and 28.3 square kilometers of land lost during the years of 1979-1989, 1989-2000 and 2000-2010 respectively.

Scientists have also observed that the driving forces for coastline changes have significant temporal heterogeneity: in the period of 1980 to 1990, the main driving force for coastline change was estuary sedimentation, especially in the Yellow River estuary, while the main driving force was tidal flat reclamation for aquaculture during 1990 to 2000, and the driving force for coastline change in the last decades has been the interaction of aquaculture and port construction (click here for more information).
