Editing Mortality Count (Organisms) (section)

== Monitoring and Measurement ==
Monitoring organism mortality involves a combination of field surveys, remote sensing, and laboratory analyses. Scientific institutions employ standardized protocols to count dead organisms or estimate mortality rates within defined populations or areas. Methods include direct counts, carcass surveys, and population censuses conducted periodically to capture temporal trends. Chemical analyses may accompany mortality assessments to identify toxic stressors. Data collection is often coordinated by environmental agencies and research organizations to ensure consistency and reliability.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.
