Abstract

We present gas-phase metallicity measurements for 583 emission line galaxies at 0.31. These results all suggest that there is little evolution in star-forming interstellar medium conditions from z∼1 to z=0, confirmed with a more complete sample of low-mass galaxies than has previously been available in this redshift range.
