火山口湖位于俄勒冈州火山口湖国家公园的马扎马火山口。该湖的表面积约为53平方公里，海拔1882米，最大深度为594米。1896年至1981年期间对这个超贫营养湖泊进行了有限的研究，导致了为期10年的湖沼学研究，以评估任何潜在的水质退化。没有观察到可归因于人类活动的水质长期变化。在这项研究成功的基础上，建立了一个永久的湖沼学计划，并制定了一个长期的监测计划，以确保为未来提供可靠的数据库。同样重要的是，该计划作为一个研究平台，开发和沟通，以公众更好地了解耦合的生物，物理和地球化学过程中的湖泊及其周围环境。这个特殊的卷代表了我们目前的知识状态，这个原始生态系统的状态，包括其特殊的光学特性，藻类营养限制，浮游细菌，以及热特性，营养物，浮游植物，深水混合和水预算的相互关系的模型。
Crater Lake is located in the caldera of Mount Mazama in Crater Lake National Park, Oregon. The lake has a surface area of about 53 km(2) at an elevation of 1882 m and a maximum depth of 594 m. Limited studies of this ultraoligotrophic lake conducted between 1896 and 1981, lead to a 10-year limnological study to evaluate any potential degradation of water quality. No long-term variations in water quality were observed that could be attributed to anthropogenic activity. Building on the success of this study, a permanent limnological program has been established with a long-term monitoring program to insure a reliable data base for use in the future. Of equal importance, this program serves as a research platform to develop and communicate to the public a better understanding of the coupled biological, physical, and geochemical processes in the lake and its surrounding environment. This special volume represents our current state of knowledge of the status of this pristine ecosystem including its special optical properties, algal nutrient limitations, pelagic bacteria, and models of the inter-relationships of thermal properties, nutrients, phytoplankton, deep-water mixing, and water budgets.
