Gravitational lensing is a powerful astrophysical and cosmological probe particularly valuable at submillimeter wavelengths for the study of statistical individual properties dusty starforming galaxies. However identification gravitational lenses often time-intensive, involving sifting large volumes imaging or spectroscopic data to find few candidates. We used early from Herschel Astrophysical Terahertz Large Area Survey demonstrate that wide-area surveys can simply easily detect strong...
