Abstract
The CHAOS survey has measured high-quality optical spectra in 100s of Hii regions across 11 nearby spiral galaxies. This dataset represents the most accurate and precise study of direct CEL abundances across a broad range of physical conditions in extragalactic Hii regions to date, and so provides a rich database from which an absolute nebular abundance scale can be calibrated.
