Abstract. The well established correlation that shows radio sources exhibiting ultra-steep spectrum are normally at higher redshift. This correlation ensured exploitation of the potential high redshift candidates from the last three decades. In order to continue the search for high redshift radio galaxies, we have extracted the ultra-steep spectrum samples from 150 MHz radio observations of the well-studied DEEP2 deep fields at higher frequencies centered on 1652+3455, 2330+0000 and 0230+000, which were carried out using the Giant Metrewave Radio Telescope (GMRT). We present here one of the observed deep-fields centered on 2330+0000 whose deep 150 MHz GMRT image has an rms noise of ∼0.9 mJy/beam. The source catalog of this deep field contain around 389 sources within 20% peak primary beam response. After careful estimation of spectral indices by cross-correlating each source in our catalog to the already available radio catalogs from NVSS and FIRST surveys at 1400 MHz, we found about 140 steep spectrum radio sources with spectra steeper than 1. We will further study these steep spectrum sources through SDSS and DEEP2 optical catalogs to search potential high redshift candidates.
