SBR-9511627 Martin I. Hoffert, Principal Investigator (PI) Andrei Lapenis, Co-PI New York University Understanding Atmosphere-Soil Interactions - A Pilot Study of Historic Russian Soils Archived samples of soils located at the Russian Academy of Forestry in St. Petersburg are well documented and in exceptionally good condition after a century of storage. US and Russian investigators will identify samples from the collection and corresponding sites for future studies on soil dynamics in relation to post-industrial atmosphere-soil interactions. Atmosphere-soil interactions targeted for study include carbon cycling, acid rain deposition and effects on buffering capacities of soils, and atmospheric contaminants of the post-industrial era. The approach is to establish a suite of samples and corresponding collection sites along a climate/soil gradient that can be revisited in 1996/1997. Selecting samples along a gradient enhances understanding of processes that control atmosphere-soil interactions such as how rates of carbon turnover vary along a precipitation gradient. This pilot project will ascertain the condition of selected samples, availability of documentation on corresponding sites from which the samples are believed to have been taken, and the condition of the corresponding sites.

SBR-9511627马丁岛Hoffert，主要研究者（PI）Andrei Lapenis，联合PI纽约大学 了解大气-土壤相互作用-俄罗斯历史土壤的初步研究 位于彼得堡的俄罗斯林业科学院保存的土壤样本记录良好，经过世纪的储存，保存状况非常好。 美国和俄罗斯的研究人员将从收集的样品和相应的地点确定未来的土壤动态研究与工业化后的大气-土壤相互作用。 大气-土壤相互作用的研究目标包括碳循环、酸雨沉积和对土壤缓冲能力的影响，以及后工业时代的大气污染物。 方法是建立一套样品和相应的收集地点，沿着气候/土壤梯度，可在1996/1997年重新访问。 沿着梯度选择样本可以增强对控制大气-土壤相互作用的过程的理解，例如碳周转率如何沿着降水梯度变化。 这一试点项目将确定选定样本的状况、据信样本取自的相应地点的文件是否齐备以及相应地点的状况。
