This article presents the results of a three-year effort at applying inform
ation technology to the problem of collaborative natural resource managemen
t in San Diego Bay. As such, it represents an approach to integrated coasta
l zone management (ICZM). This effort resulted from a collaboration between
the San Diego Supercomputer Center at the University of California, San Di
ego and the San Diego Bay Interagency Water Quality Panel for the purpose o
f (1) developing an environmental data repository to facilitate the acquisi
tion and sharing of data and (2) the development of a visual model of the b
ay in support of the development of a comprehensive, coordinated management
plan for San Diego Bay. It was determined from this study that information
technology is an important and key component to ICZM but that sociopolitic
al factors may override the benefits of decision-support systems and should
be considered at the outset of any project of this kind.
