/ Abstract
The ISM metallicity and the stellar mass are examined in a sample of 66 galaxies at 0.4 < z < 1, selected from the Gemini Deep Deep Survey (GDDS) and the Canada‐France Redshift Survey (CFRS). We observe a mass‐metallicity relation similar to that seen in z ∼ 0.1 SDSS galaxies, but displaced towards higher masses and/or lower metallicities. Using this sample, and a small sample of z ∼ 2.3 LBGs, a redshift dependent mass‐metallicity relation is proposed which describes the observed results.
