... By taking advantage of atomic hydrogen (HI) observations obtained as part of the GALEX Arecibo SDSS and ALFALFA surveys, I will demonstrate that the combination of deep, targeted observations and spectral stacking of blind, large-area shallow surveys is critical in order to characterize how the gas content of galaxies depends on their structure, star formation activity and environment. ...

0.1-0.3 M sun yr-1, and calibrations of SFRs based on L(70) and L(160) are proposed. Below those two luminosity limits, the relation between SFR and 70 ЮМm (160 ЮМm) luminosity is nonlinear and SFR calibrations become problematic. ... We interpret this increasing dispersion as an effect of the increasing contribution to the infrared emission of dust heated by stellar populations not associated with the current star formation. ...
