S. ; Bushouse, H. ; Hunter, D. A. Abstract Observations of 0 II λ 3727 and Hβ emission-line strengths are presented from large-aperture spectro-photometric observations of nearby (z < 0. 1) optically blue galaxies covering a wide range in surface brightness and luminosity. The 0 II emission-line equivalent widths in these galaxies primarily lie between 30 and 100 A. Emission-line strengths in nearby blue galaxies thus resemble those found in faint galaxies at moderate-to-high redshifts (z < 0. 9). The most actively star-forming nearby galaxies are characterized by surface brightness in the 0 II line of ~10^-15^-10^-14^ ergs s^-1^ cm^-2^ arcsec^-2^ over spatial distances of more than 1 kpc. The fluxes of the O II and Hβ emission lines are well correlated, and thus O II luminosities can be used to derive approximate star-formation rates in blue galaxies.
