Includes abstract. / Includes bibliographical references (leaves 95-99). / We use the HI velocity profiles of The HI Nearby Galaxy
Survey (THINGS) galaxies to study the phase structure of the interstellar medium (ISM) and its relation to
galaxy properties and morphology. To construct high signal-to-noise (S/N) profiles, we use a method analogous
to the stacking method sometimes used in high redshift HI observations. We call these high S/N profiles
'super profiles'. By decomposing the super profiles into Gaussian components, we find broad and narrow components in all our analyzed galaxies.
