The PEARS (Probing Evolution And Reionization Spectroscopically) project provides an enormous dataset of low-resolution spectra from thousands of galaxies in the GOODS North and South fields. Here we present results of a search for emission line galaxies in PEARS using a unique 2D detection method that utilizes the observation that many emission lines originate from clumpy knots within galaxies (Meurer 2005). This 2D line-finding method proves to be useful in detecting emission lines from compact knots within galaxies that might not otherwise be detected using more traditional 1D line-finding techniques. Preliminary results in the Hubble Ultra Deep Field indicate that 5% of galaxies--79 in total--to 27 mag display prominant emission lines. 14% of these 79 galaxies display a merging/interacting morphology. Completion of the remaining ACS fields will result in a catalog of 600-900 emission line sources. From these line emitters we can derive the luminosity function of [OII] and [OIII] lines at z= 0.5-1.
