Webb[1] Lake sediments are “hot spots” of methane production in the landscape. However, regional and global lake methane emissions, contributing to the greenhouse effect, are poorly known. We developed predictions of methane emissions from easily measured lake characteristics based on measurements for 11 North American and 13 Swedish lakes, …
WebbLakes are most often classified based on their productivity, i.e., the amount of algae and aquatic plants that the lake can support. They also may be classified based on size or hydrology (drainage), plant or animal communities, or the way humans use them (water supply, recreation, amount of development, and navigation). lab aids energy activity 2Webb7 aug. 2024 · The process of a lake becoming more productive is called eutrophication.
