Scientific paper

Spectroscopic observations of the star CPD -59 2603 in the Carina Nebula have been obtained with STIS using the near and far UV high-resolution echelle modes. The resolving power is approximately 110,000 with a signal to noise of 30. The interstellar absorption lines along this sightline exhibit complex velocity and excitation structure, from which three distinct regions can be identified: multiple, very-high-velocity components formed within the nebula: the warm, globally expanding HII region; and cool, low-velocity gas probably associated with clouds near the Sun. The behavior of the atomic species Mg I, MgII, SiIV, and CI are discussed. Similarly, the heavy element species OI, NiII, CuII and GaII are detected and discussed.
