High altitude lakes: limnology and paleolimnology

The most remote regions of globe represent some of the least disturbed ecosystems, yet they are threatened by air pollution and by climatic change. The Himalaya is one of the most isolated regions in the world and least explored wildernesses outside the Polar Regions; and it is for this reason that the Tibetan Plateau is often referred to as the ‘Third Pole’. Limnological survey (including chemistry, biology and sediment core studies) of lakes located between ca. 4500 and 5500 m a.s.l. has been performed from 1992 in the Kumbhu Valley, Nepal. Lake water chemical surveys reveal a constant increase of the ionic content of the lake water probably related to glacier retreat. Modern phytoplankton data compared with previous data point to an increasing trend in lake productivity. Zooplankton, benthos and thechamoebians provide useful biogeographical information. Paleolimnological reconstructions show the potential use of these sites in providing proxy data of past climatic changes in high altitude regions. Data collected of persistent organic pollutants show that the studied sites receive input related to long-range transport pollution. The aims and rationale for the future development of the Ev-K2-CNR Limnological Information System is discussed.
