N2  - We present preliminary results from the Southern Galactic Plane Survey (SGPS) Test Region and Parkes data. As part of the pilot project for the Southern Galactic Plane Survey, observations of a Test Region (325&#183;5&#176; &#8804;l &#8804; 333&#183;5&#176;; &#8722;0&#183;5&#176; &#8804; b &#8804; 3&#183;5&#176;) were completed in December 1998. Single-dish observations of the full survey region (253&#176; &#8804; l &#8804; 358 &#176; |b| &#8804; 1&#176;) with the Parkes Radio Telescope were completed in March 2000. We present a sample of SGPS H I data, with particular attention to the smallest- and largest-scale structures seen in absorption and emission, respectively. On the large scale, we detect many prominent H I shells. On the small scale, we note extremely compact, cold clouds seen in H I self-absorption. We explore how these two classes of objects probe opposite ends of the H I spatial power spectrum.
