Abstract
Data analysis tasks at an Ocean Observatory require in-
tegrative and domain-specialized use of techniques from
database, workflow, and visualization systems. We de-
scribe a platform to support these tasks developed as part
of the cyberinfrastructure at the Center for Coastal Mar-
gin Observation and Prediction integrating a provenance-
aware workflow system, 3D visualization, and a remote
query engine for large-scale ocean circulation models. We
show how these disparate tools complement each other
and give examples of real scientific insights delivered by
the integrated system. We conclude that data manage-
