Limnology
Definition
The scientific study of the biology, chemistry, and physics of inland waters (lakes, rivers, ponds, wetlands). Its reference databases of species assemblages and water-chemistry profiles underpin forensic aquatic evidence interpretation.
- Subject
- Inland waters: lakes, rivers, ponds, wetlands
- Scope
- Biology, chemistry and physics of these systems
- Forensic role
- Reference databases for species and chemistry comparison
Common questions
How does limnology differ from hydrology in a forensic context?+
Hydrology focuses on water movement and flow. Limnology focuses on the biological and chemical character of a specific water body, which is what makes it comparable and source distinctive for casework.
Why do reference databases matter for limnology-based evidence?+
Without documented baseline data for a given lake or river, an examiner has nothing to compare recovered diatoms or water chemistry against, so the comparison collapses to guesswork.
