New Guinea Glacier Fluctuations Between 20 and 10 Ka

标题：20 - 10Ka之间的新几内亚冰川波动该SGER奖支持对20 - 10Ka末次冰期-间冰期过渡期间新几内亚西部（Irian Jaya）热带冰川波动的调查研究。这项研究将强调放射性碳年代学。该项目有四个目标：(1)地形测绘；(2)冰川重建；(3)年代学；(4)与冰模型和植被研究的联系。主要的油田区域将是新几内亚最高的山峰Jaya山（海拔4884米）以北的Kemabu高原。这是一个探索性的建议，在偏远的伊里安查亚高原的后勤运作相当困难，获得放射性碳定年的合适材料的潜力是未知的。伊里安查亚毗邻热带西太平洋的“暖池”，这是地球上最温暖的地区。伊里安查亚冰川记录应能较好地反映暖池区平均温度的变化。由于暖池地区的温度对热带水蒸气“喷泉”有主要影响，伊里安查亚冰川记录也监测全球大气的水蒸气含量。

Abstract ATM-9408711 Prentice, Michael L. University of Maine Title: New Guinea Glacier Fluctuations Between 20 and 10Ka This SGER Award supports a reconnaissance study of tropical glacier fluctuations in western New Guinea (Irian Jaya) during the last glacial-interglacial transition from 20 to 10Ka. The study will emphasize radiocarbon chronology. The project has four objectives: (1) topographic mapping, (2) glacier reconstruction, (3) chronology, and (4) linkage to ice-modeling and vegetation studies. The principal field area will be the Kemabu plateau a tableland north of the highest mountain on New Guinea, Mt. Jaya (4884 m). This is an exploratory proposal, logistical operations in the remote Irian Jaya highlands are quite difficult and the potential of obtaining suitable material for radiocarbon dating is unknown. Irian Jaya is adjacent to the tropical western Pacific "warm pool," the warmest region on the planet. The Irian Jaya glacial record should closely reflect the average temperature variability of the warm-pool region. Because the temperature of the warm-pool region exerts a dominant influence on the tropical water-vapor "fountain," the Irian Jaya glacial record also monitors the water-vapor content of the global atmosphere.
