I'll start off describing the Herschel ATLAS survey including source
detection and identification with optical galaxies.

Then I'll discuss results from three science areas:
 * fitting model SEDs to multi-wavelength data
 * source counts
 * clustering of sources

The conclusions are that H-ATLAS galaxies are a bimodal population: at
low redshift they are fairly normal low-mass galaxies, but at high
redshift they are more massive star-forming galaxies.
