Limnology is the study of waters that are not part of the oceans or seas. These are rivers, lakes, swamps, water under the ground, and even bodies of water made by people. Scientists who do this are called limnologists. Their work includes biology, chemistry, geology, and hydrology. Limnology is the scientific study of the life and phenomena of inland water, including lakes, rivers, streams and wetlands. The Center for Limnology at CIRES exists to promote research and teaching related to inland aquatic ecosystems, including lakes, streams, and wetlands.
