| Abstract: | Area spectroscopy has significant advantages over both traditional imaging and long-slit spectroscopy: it is more efficient
in observing time, and yields substantially more information. Through Integral Field Units, area spectroscopy is becoming
an essential part of new facility instruments on the latest large telescopes. We have been undertaking a programme on the
Gemini 8-m telescopes to demonstrate the power of integral field spectroscopy, using the optical GMOS spectrograph, and the
new CIRPASS instrument in the near-infrared. Here we present some preliminary results from 3D spectroscopy of z ∼ 1 objects, mapping the emission lines in a 3CR radio galaxy and in a gravitationally lensed arc.
