Quaternary History of Vegetation and Climate of Hawaii

夏威夷群岛的古生态研究将提供新的信息，说明在最后一次冰川高峰期之前、期间和之后热带太平洋海洋系统的变化，或许有助于更好地了解大陆和海洋温度记录之间的差异。过去植被的变化将通过泥炭沼泽和埋藏在熔岩流下的土壤中的花粉、木材和木炭化石来确定。将开发统计解释方法，将现代花粉组合和植物分布与群岛现代气候的广泛数据库联系起来。已经发现了四个泥炭沼泽，海拔从500米到1400米不等，记录的时间从现在追溯到最后一次冰川高峰期，其中两个泥炭沼泽的底部日期分别为36,000年和41,000年。已经可以从100多个埋藏的木炭矿床中获得样本。化石遗址沿海拔样带和受信风控制的降雨梯度的位置意味着它们可以提供有关过去错失率、信风强度和信风逆温高度的信息。

Paleoecological research in the Hawaiian Islands will provide new information about whether systems of the tropical Pacific Ocean before, during and since the last glacial maximum, perhaps leading to a better understanding of the discrepancy between continental and marine temperature records. Changes in past vegetation will be determined from fossil pollen, wood and charcoal in peat bogs and in soils buried beneath lava flows. Statistical methods of interpretation will be developed, relating modern pollen assemblages and plant distributions to the extensive data base on modern climates on the Islands. Four peat bogs have been located, at elevations varying from 500 m to 1400 m above sea level, with records extending from the present back to the last glacial maximum, and two of the bogs have bottom dates 36,000 and 41,000 years. Samples are already available from over 100 buried charcoal deposits. The locations of fossil sites along an elevational transect and rainfall gradient controlled by the trade winds means they can provide information about past lapse rates, the strength of the trade winds and the elevation of the trade wind inversion.
