Stratigraphy, chronology, and paleoclimatology of Hawaiian Eolian Sediments

夏威夷的古气候记录包含了冰盖冰川反复出现的证据，这与过去20万年的海洋氧同位素记录有关。与这些冰川沉积相关的是沉积沉积，表明过去的风的强度和方向。这项建议要求支持一个实地项目，研究这些风沙沉积物、互层古土壤和冰盖，以重建该地区的风向和强度的冰川-间冰期历史。结果将被用来检验GCM对最后一次冰川最大值的风场模拟的有效性。该项目将首次对太平洋盆地亚热带地区过去的风力强度和风向进行限制。

The paleoclimatic record on Hawaii contains evidence of recurring ice-cap glaciation that has been correlated with the last 200,000 years of the marine oxygen isotope record. Associated with these glacial deposits are sedimentary deposits indicative of past wind intensity and direction. This proposal requests support for a field program to study these eolian sediments, interbedded paleosols, and tephras in order to reconstruct the glacial-interglacial history of wind direction and intensity for this region. The results will be used to test the validity of GCM wind simulations for the last glacial maximum. This project will provide the first constraints on past wind intensity and direction in the subtropical region of the Pacific basin.
