阿迪朗达克湖调查公司 (ALSC) 是纽约州环境保护部和帝国州电力研究公司合作成立的，旨在更好地描述阿迪朗达克湖的化学和生物状况。 1984 年至 1987 年间，ALSC 调查了阿迪朗达克生态区内的 1469 个湖泊。作为调查的后续行动，ALSC 赞助了对 ALSC 数据库的一系列解释性分析。这些分析的主要目的如下： 评估无机酸（来自酸性沉积）和非无机酸（天然有机酸）对湖泊 pH 水平的影响；根据预期影响阿迪朗达克湖泊对酸性沉降变化的响应的湖泊和流域特征对阿迪朗达克湖泊进行分类；评估阿迪朗达克湖对环境条件变化的敏感性，例如无机酸或溶解有机碳浓度的变化；确定对于解释目前观察到的阿迪朗达克湖泊鱼类群落状况很重要的湖泊特征，特别是湖泊酸度的相对重要性；通过使用阿迪朗达克鱼类群落的可用历史数据和 ALSC 数据库，评估阿迪朗达克鱼类群落随时间发生的变化以及这些趋势的可能原因；更多» 并确定现有鱼类资源可能面临持续酸性沉积风险的程度，或者如果酸度水平降低可能会恢复的程度。基本方法检查了 ALSC 数据库中观察到的流域特征、湖泊化学和鱼类状况之间的关系。单独的报告针对数据库进行单独处理。« less
The Adirondack Lakes Survey Corporation (ALSC) was formed as a cooperative effort of the New York State Department of Environmental Conservation and the Empire State Electric Energy Research Corporation to better characterize the chemical and biological status of Adirondack lakes. Between 1984 and 1987, the ALSC surveyed 1469 lakes within the Adirondack ecological zone. As a follow-up to the survey, the ALSC sponsored a series of interpretive analyses of the ALSC data base. The primary objectives of these analyses were as follows: Evaluate the influence of mineral acids (from acidic deposition) and nonmineral acids (natural organic acids) on lake pH levels; classify Adirondack lakes according to lake and watershed features expected to influence their responsiveness to changes in acidic deposition; evaluate the sensitivity of Adirondack lakes to changes in environmental conditions, such as changes in mineral acids or dissolved organic carbon concentrations; identify lake characteristics important in explaining the observed present-day status of fish communities in Adirondack lakes, in particular the relative importance of lake acidity; evaluate changes that have occurred over time in Adirondack fish communities and probable causes for these trends by using the available historical data on fish communities in the Adirondacks and the ALSC data base;more » and determine the degree to which the existing fish resource might be at risk from continued acidic deposition, or might recover if acidity levels were reduced. The basic approach examined relationships observed in the ALSC data base among watershed characteristics, lake chemistry, and fish status. Individual reports are processed separately for the data bases.« less
