The W43 region is one of the most massive star forming regions in our Galaxy. It is subject to a large IRAM 30m project that observes high spectral resolution maps of the complete complex in the 13CO (2–1) and C18O (2–1) lines. We find a variety of different sources of which we calculate excitation temperature, H2 column density and mass. We find the total mass of dense clouds in the complex to be 1.2×106 M⊙.
