What is HOLOS?

Holos is a multifaceted project, originally conceived and initiated in 2015, which aims to digitize and aggregate many diverse biological and environmental collections into the Berkeley Ecoinformatics Engine (‘Ecoengine’), a web service that can be searched and visualized via graphical tools: Explore, Compare, and other Applications. Primarily Holos focused on liberating ‘dark data’ from the repositories at UC Berkeley in order to achieve a holistic understanding of the complex interactions and feedback among organisms, climate, and their physical and biotic environments across space and time. The data in the Ecoengine is global in scope, and since much of the data is sourced from BNHM museums, reserves and partners, and the data coverage for California is thorough.
