Abstract ATM-952664 Prentice, Michael L. University of New Hampshire Title: High-Resolution Coastal Record of Western Equatorial Pacific and Adjacent Highland Climate During the Last Glacial Cycle The goal of this study is to derive a high-resolution coupled record of surface and high-altitude climate change in the western Pacific warm-pool (WPWP) over the last glacial cycle. The record will come from Cenderawasih Bay on the northwest coast of New Guinea. Because of its position, proxy records in Cenderawasih Bay concurrently monitor the temperature and hydrology of the core WPWP as well as changes in temperature and precipitation on the directly adjacent Irian Jaya highland. The program involves a seismic survey and piston cores will be collected. WPWP temperature and precipitation changes will be distinguished using foraminiferal isotope records supplemented by SST estimates derived from transfer-function analysis of planktonic foraminiferal census data. High-altitude paleoclimate changes caused significant fluctuations in the extent of high-altitude glaciation as well as the composition and elevation of vegetation zones. Glacier, vegetation, and climate changes also will be reconstructed. By filling a large spatial and temporal gap in tropical paleoclimate reconstructions, this project will contribute to understanding the role of the global tropical climate system in large-magnitude global changes on sub-millennial timescales.***

摘要ATM-952664普伦蒂斯，迈克尔L。 新罕布什尔州大学题目：西赤道太平洋高分辨率海岸记录 末次冰期循环期间的气候变化 本研究的目的是获得一个高分辨率的耦合记录的地面和高海拔的气候变化在西太平洋暖池（WPWP）在末次冰期旋回。 这一记录将来自新几内亚西北海岸的Cenderawasih湾。 由于其位置，Cenderawasih湾的代理记录同时监测核心WPWP的温度和水文以及直接相邻的伊里安查亚高地的温度和降水变化。 该计划包括地震勘探和活塞芯将收集。 WPWP的温度和降水变化将区分有孔虫同位素记录补充SST估计来自于传递函数分析的浮游有孔虫普查数据。 高海拔古气候变化引起了高海拔冰川作用的范围以及植被带的组成和海拔的显著波动。 冰川、植被和气候变化也将被重建。 通过填补热带古气候重建中的巨大空间和时间空白，该项目将有助于了解全球热带气候系统在亚千年时间尺度上大规模全球变化中的作用。
