Causal Analysis/Diagnosis Decision Information System (CADDIS) Webinar Archive

Presented December 13, 2017 by EPA scientist Sue Norton, this webinar highlighted EPA's Causal Analysis/Diagnosis Decision Information System (CADDIS), which is an on-line resource that helps scientists find, organize and use information to determine the likely causes of adverse biological effects in aquatic ecosystems. CADDIS offers a wealth of information on common stressors such as physical habitat, nutrients, metals, pH, toxic substances and temperature, as well as suggestions and tools for analyzing data. Recent case studies in Pennsylvania and California were also discussed.
