中文摘要
9218951莱文特奖支持一项关于纬度样带表层沉积物(现有样本)中的硅藻组合与该样带当前海洋和环境条件之间关系的研究。这项工作将确定使用硅藻组合作为自上一次冰盛期以来气候的替代记录的可行性。这项工作将使用定量方法来描述硅藻组合,并将包括对通过研究两个沉积物岩芯中的硅藻而开发的模型进行测试,其中一个来自布兰斯菲尔德海峡(开阔水域),另一个来自Gerlache海峡的一个峡湾,其中已经有一些古气候和古环境指标可用作基线。这项研究对于开发将生物活动记录,特别是硅藻产生的藻类与气候和环境条件联系起来的可行模型至关重要。***
英文摘要
9218951 Leventer This award supports a study of the relationship between diatom assemblages in surface sediments (from existing samples) along a latitudinal transect and current oceanographic and environmental conditions along the transect. This work will determine the viability of using diatom assemblages as proxy records of climate since the last glacial maximum. The work will use quantitative methods to describe diatom assemblages and will include a test of the model developed by studying diatoms in two sediment cores, one from Bransfield Strait (open water) and the other from a fjord in Gerlache Strait, in which there are already some paleoclimatic and paleoenvironmental indicators to use as a baseline. This study is essential to the development of viable models relating records of biological activity, and in particular diatom producing algae, to climatic and environmental conditions. ***
