Funding is provided to recover and analyze ice cores from glaciers in the tropical Pacific to examine tropical climate variability especially El Nino-Southern Oscillation (ENSO) linked climate phenomena such as the Austral-Asian monsoon system, the abrupt 4,000 year drought, and the modulation of Atlantic and Pacific tropical storm intensities. Specifically, the researchers will recover four cores to bedrock from the two of the three remaining ice fields on Puncak Jaya (PJ) in Irian Jaya, Indonesia on the Island of New Guinea and two cores from Nevado Hualcán in the Cordillera Blanca, Peru. Climatologically, tropical ice masses are particularly sensitive to small changes in ambient temperatures since they exist very close to the melting point of water. Scientific evidence exists for recent and strong warming in the tropics that is signaled by the disappearance and rapid retreat of ice caps and glaciers at high elevations. General circulation models of possible future climate change indicate that warming will increase most rapidly at higher altitudes and especially in the tropical latitudes where these glaciers are located. Scientific interest in the study of the Puncak Jaya and Hualcán ice fields, both in the analysis of the cores and in the measurements of area and volume changes of the glaciers themselves, arises in part from the need to place the recent and accelerating ice retreat into a longer temporal perspective.Furthermore, the analyses of the Hualcán ice cores and accompanying mass balance studies will help provide critical information about water resources in Peru. Runoff from glaciers feed Peru's streams and rivers and is essential for irrigation, hydroelectric production (80% of Peru?s electricity), and municipal water supplies. The planned project supports students in an effort to expand our fundamental knowledge of climate across time and space. The research also provides for true intellectual and financial collaborations between academia, non-governmental organizations, and governments in several nations.

提供资金，以恢复和分析热带太平洋冰川的冰芯，以研究热带气候变化，特别是厄尔尼诺-南方涛动（ENSO）相关的气候现象，如澳大利亚-亚洲季风系统，突然的4,000年干旱，以及大西洋和太平洋热带风暴强度的调制。具体来说，研究人员将从新几内亚岛印度尼西亚伊里安查亚的Puncak Jaya（PJ）剩余的三个冰原中的两个中恢复四个核心到基岩，并从秘鲁科迪勒拉布兰卡的Nevado Hualcán恢复两个核心。 从气候学上讲，热带冰块对环境温度的微小变化特别敏感，因为它们非常接近水的熔点。有科学证据表明，热带地区最近出现了强烈的变暖，这是由高海拔地区冰盖和冰川的消失和迅速退缩所标志的。未来可能气候变化的大气环流模型表明，变暖将在高海拔地区加速得最快，尤其是在这些冰川所在的热带纬度地区。对Puncak Jaya和Hualcán冰原研究的科学兴趣，包括对冰芯的分析和对冰川本身面积和体积变化的测量，部分原因是需要从更长的时间角度看待最近和加速的冰川退缩。对瓦尔坎冰芯的分析和伴随的质量平衡研究将有助于提供有关秘鲁水资源的重要信息。冰川径流滋养着秘鲁的溪流和河流，是灌溉、水力发电（占秘鲁？电力和市政供水。计划中的项目支持学生努力扩展我们对跨时间和空间气候的基础知识。该研究还为学术界、非政府组织和几个国家的政府之间提供了真正的知识和财政合作。
