The Role of Biogenic Factors in Precipitation of Calcium Carbonate in Freshwater

在杜桑·斯多克、萨格勒布的鲁杰·博斯科维奇研究所和波士顿大学的斯特杰普科·戈卢比奇之间为期两年的美国-南斯拉夫生态合作研究项目中，研究人员将对一个典型的淡水系统进行完整的案例研究。这项研究将侧重于南斯拉夫喀斯特地区的普利特维斯湖和瀑布。目的是确定影响这些瀑布和钙华沉积物中碳酸钙形成的主要生物活动。将使用多学科分配方法。南斯拉夫的研究小组在水化学和一般化学方面拥有专门知识。生物学研究将由美国调查员进行。这位美国科学家将确定生物的物种组成和在形成瀑布中的生态作用，并确定生物矿物形成。该项目得到了美国-南斯拉夫科学技术合作联合委员会的批准，并由一个由美国和南斯拉夫两国政府提供同等捐款的联合基金提供支助。美国的捐款每年由国务院提供。没有NSF基金参与其中。赠款是给南斯拉夫的主要科学机构，但包括美国科学家前往南斯拉夫旅行的美元资金和南斯拉夫科学家在美国的生活费。

In this two-year U.S.-Yugoslav cooperative research project in ecology between Dusan Srdoc, Rudjer Boskovic Institute in Zagreb and Stejepko Golubic at Boston University, the investigators will carry out a complete case study of a typical freshwater system. The study will focus on the Plitvice Lakes and waterfalls in the karstic region of Yugoslavia. The goal is to identify the principal biological activities that influence calcium carbonate formation of these waterfalls and travertine deposits. A multidisciplinary apporach will be used. The Yugoslav research team has expertise in aquatic chemistry and chemistry in general. The biological research will be carried out by the U.S. investigator. The U.S. scientist will determine the species composition and ecological role of organisms in forming cascades, and identify biological mineral formations. This project was approved by the U.S.-Yugoslav Joint Board on Cooperation in Science and Technology and is supported through a joint fund consisting of matching contributions from the governments of the United States and Yugoslavia. The U.S. contribution is provided annually by the Department of State. No NSF funds are involved. Grants are made to the principal scientific institution in Yugoslavia, but include dollar funds for U.S. scientist travel to Yugoslavia and for Yugoslav scientists' living expenses in the U.S.
