9809606 Charles This award supports the establishment of the Diatom Paleolimnology Data Cooperative (DPDC). Diatoms are used widely to infer climate characteristics from lake sediment cores. New methods for inferring past climatic conditions are developing rapidly, and many diatom-based studies are addressing key climate issues. The purpose of the DPDC is to both 1) provide the climate change community with improved and more accessible estimates of past temperature, precipitation, water chemistry, lake level and hydrologic characteristics, and 2) provide diatom paleolimnologists with data that will significantly improve their ability to produce such estimates. In addition to ecological data, the DPDC is designed to contain the climate related inferences from diatom paleolimnology studies of sediment cores. Long- and short-term values of inferred salinity, lake level, and other characteristics are very useful to paleoclimate researchers for understanding past climate systems and for developing and evaluating climate models. All data will be stored in a standard format. It will be freely available to the scientific community. ***

小行星9809606 该奖项支持建立硅藻古湖沼学数据合作社（DPDC）。 硅藻被广泛用于从湖泊沉积物岩心推断气候特征。 推断过去气候条件的新方法正在迅速发展，许多以气候变化为基础的研究正在解决关键的气候问题。 DPDC的目的是：1）为气候变化界提供过去温度，降水，水化学，湖泊水位和水文特征的改进和更容易获得的估计，2）为硅藻古湖泊学家提供数据，这将显着提高他们产生这种估计的能力。 除了生态数据，DPDC的目的是包含气候相关的推断，从硅藻沉积岩芯的古湖沼学研究。 长期和短期的盐度、湖泊水位和其他特征的推断值对于古气候研究人员了解过去的气候系统以及开发和评估气候模型是非常有用的。 所有数据将以标准格式存储。 它将免费提供给科学界。 ***
