The aim of the high energy heavy ion programs at the SPS and AGS accelerators is to study nuclear matter under conditions of extremely high densities and temperatures. Theoretical calculations predict that under such conditions hadronic matter might undergo a phase transition to a new form of matter, the quark-gluon plasma or QGP, in which quarks and gluons are deconfined over an extended volume. A broad spectrum of possible signatures has been suggested. An unfortunate common characteristic of most of these signatures is the necessity to distinguish them from the background created by ordinary hadronic processes. A thorough understanding of the reaction mechanisms in high energy heavy ion collisions is, therefore, an important prerequisite in any QGP search. Global event quantities like the transverse energy E_T, the forward energy E_F, and the charged particle multiplicity have proven to be valuable tools for obtaining this understanding of the reaction mechanisms. In this contribution to the Hadron Structure 1991 Conference will be presented results concerning the transverse energy and forward energy extracted from WA80's calorimeters in a series of measurements using beams of ¹⁶O and ³²S bombarding nuclear targets.
