Massardi et al. introduce the Serendipitous H-ATLAS-fields Observations of Radio Extragalactic Sources (SHORES) survey. SHORES is a multiple pencil beam survey of 29 fields within the Herschel-ATLAS Southern Galactic Field at 2.1 GHz with the ATCA. The paper presents the observations, calibration and analysis of the 27 shallow fields that cover an overall area of ∼26 square degrees with sensitivity at the phase centers of around 33 µJy. Two additional (deep) fields have been observed to even higher sensitivity. The SHORES shallow-field sample contains 2294 sources and is 95% reliable above 497.5 µJy. By exploiting the ATCA E-W 6 km configuration, resolutions of 3.2 × 7.2 arcsec were reached, to which level 81% of our sources are unresolved. The figure above shows the H-ATLAS map of the Soutern Galactic Pole region, superimposed with the footprints of the SHORES shallow fields. The center of each field coincides with a candidate lensed galaxy.
