1) APEX will conduct several extragalactic surveys including molecular gas surveys of galaxy clusters and centers using CO lines, a Sunyaev-Zel'dovich cluster survey, and a submillimeter deep field survey of nearby galaxies. 2) The APEX SZ Camera will map large areas of the sky to detect galaxy clusters via the Sunyaev-Zel'dovich effect using 320 pixels at 150 GHz. 3) Early results from the LABOCA camera include a deep 850um survey of the Chandra Deep Field South detecting submillimeter galaxies out to redshift 3.
