Limnologists study physical, chemical and biological aspects of internal water systems.
Scientists who study internal waters--such as freshwater lakes, rivers, ponds, streams and wetlands and saltwater systems like the Great Salt Lake in Utah---are generally classified as limnologists.
Purpose
A limnologist's work provides an understanding of ecological water systems and protects them from negative environmental changes to maintain safety for recreational use, fishing, and plants and animals that inhabit the area. Much of their work is supported by grants.
Duties
Work includes testing waters for chemicals; determining the cause of fish deaths or unsafe conditions; studying animals, plants or microscopic plankton that live within the ecosystem; or evaluating the movement and properties of the water. Fisheries biologists, environmental scientists, chemists, hydrologists and ecologists are types of limnologists.
Work Environment
Employers include the government, universities and private businesses---such as environmental consulting firms. Field work involves collecting samples by boat or wading in the waters, although much time is also spent in laboratories conducting experiments and tests.
Requirements
Computers are used to record scientific data and to construct models. Good communication and writing skills are needed for lectures and informative research papers. Candidates should obtain at least a bachelor's degree in biology, ecology, chemistry or related field, cites the U.S. Bureau of Labor Statistics. A master's or Ph.D. is needed for college educators and to obtain higher-paid positions.
Job Outlook and Pay
Prepare for stiff competition due to limited funding and job popularity, reports the BLS. Although salaries vary due to specialization, education and experience, the University of Connecticut reports an annual salary range of $21,000 to $80,000.
