introduction lake terraces are geomorphological evidence of climate change during quaternary. location of these terraces location in different elevation shows paleo water lake level fluctuations. investigation about urmia lake terraces was conducted by bobek (1973).he found those terraces in 45-55 meter above urmia water level on that time. according to bobek, development of lake area in paleo ...

We read with interest the article titled ‘Obesity is a risk factor for acute mountain sickness: a prospective study in Tibet railway construction workers on Tibetan plateau’1. Role of obesity, as acknowledged by the authors, has been debatable in acute mountain sickness (AMS). Authors of this study have reported increasing Lake Louise (LL) score both at 12h and 24h of exposure to high altitude ...

Economic mineral deposits found in oceanic terranes include: mesothermal gold-quartz veins, Cyprus-type massive sulphide, podiform chromite. platinum or cobalt associated with nickel sulphides, as well as asbestos and jade deposits. These are rither hosted by, or otherwise closely associated with oceanic crustal or mantle lithologies. Mesothermal gold-quartz veins and related placers are histor...

Remote sensing in areas with extreme altitude differences is particularly challenging. In high mountain areas specifically, steep slopes result in reduced ground pixel resolution and degraded quality in the DEM. Exceptionally high brightness differences can in part no longer be imaged by the sensors. Nevertheless, detailed information about mountainous regions is highly relevant: time and again...

It is located 650m above sea level along the boundary between the North Caribbean and Pacific slopes, near the Southern end of the volcanic Guanacaste mountain range. In the early 1980s the lake's main outlet was dammed and the outflow was diverted into Arenal Reservoir. Lake Cote was first studied in 1990-1991, and later in 2001, before it was again modified by raising its dam by one meter to ...

The Tibetan plateau and surrounding mountain ranges contain the largest amount of ice outside the polar region. The Tibetan plateau also contains more than one thousand lakes and is the origin of a large part of the water resources of South and East Asia, the most densely populated regions on earth. Recent studies concluded that the glacial area on the Tibetan plateau and surroundings has decre...

Water level fluctuations of inland lakes are related to regional-scale climate changes, and reflect variations in evaporation, precipitation and glacier meltwater flowing into the lake area in its catchment. In this paper, Ice, Cloud and land Elevation Satellite (ICESat) altimeter data and Landsat imagery (2002–09) are used to estimate Nam Co lake (Nyainqentanglha range, Tibetan Plateau) water ...
