A 1500-year record of tropical precipitation in ice cores from the quelccaya ice cap, peru.
Two ice cores, covering 1500 years of climatic information, from the summit (5670 meters) of the tropical Quelccaya ice cap, in the Andes of southern Peru, provide information on general environmental conditions including droughts, volcanic activity, moisture sources, temperature, and glacier net balance. The net balance record reconstructed from these cores reflects major precipitation trends ...
متن کاملGLACIOLOGICAL INVESTIGATIONS OF THE TROPICAL QUELCCAYA ICE CAP, PERU* By LONNIE
Glaciological results of the continuing investigations of the Quelccaya ice cap located at lat. 13 ° 56' S., long. 70° 50 ' W., in the Cordillera Oriental of southern Peru are presented. lee cores to a depth of 15 m have been retrieved from the summit dome (5 650 m), middle dome (5543 m), and south dome (5 480 m) and sampled in detail for microparticle, oxygen-isotope, and total-,8-activity mea...
متن کاملEl nino-southern oscillation events recorded in the stratigraphy of the tropical quelccaya ice cap, peru.
Snow accumulation measured during 1982-1983 on the Quelccaya ice cap, Peru, was 70 percent of the average from 1975 through 1983. Inspection of 19 years (1964 through 1983) of accumulation measured near the summit of Quelccaya reveals a substantial decrease ( approximately 30 percent) in association with the last five El Niño-Southern Oscillation (ENSO) occurrences in the equatorial Pacific. Th...
متن کاملGlacial Records of Global Climate: A 1500-Year Tropical Ice Core Record of Climate
A general discussion is given of climate variability over the last 1500 years as interpreted from two ice cores from the Quelccaya ice cap, Peru. The possible role of climatic variability in prehistory over this period is discussed with emphases on (1) relationships between climate and the rise and decline of coastal and highland cultures; (2) the possible causes of two major dust events record...
متن کاملMeasurement of the Retreat of Qori Kalis Glacier in the Tropical Andes of Peru
The extent and volume of the largest outlet glacier from the Quelccaya Ice Cap (14°S, 71°W, 5200 m a.s.l.) has been measured four times between 1963 and 1991, once by aerial and three times by terrestrial photogrammetry. Drastic and accelerating retreat of the terminus and decrease of ice volume have been documented. The rate of retreat was nearly three times as fast between 1983 and 1991 as be...
