The EPIC Web Browser is Web application that provides interactive on-line data access to EPIC hydrographic data sets. It allows user to view the oceanographic in-situ data by creating plots on-the-fly, generating listings, data downloading etc.
The EPIC Web Browser consists of a set of perl routines which initiate back-end database access, invoke the EPIC programs to make the plot or data listing, and generate the results page dynamically. These routines are designed to be called as CGI-scripts, either with the POST or GET command. Alternatively, the scripts can also be called from inside other perl programs. Graphics are generated with the PPLUS package and Meta-files from PPLUS are converted to GIF-forma with m2gif . The EPIC Web Browser version 2.0 implements JavaScripts and Java Applets to provide highly user interactive data selection features.

The EPIC Web Browser is the analysis tool behind our Web-based interface to PMEL data. Another example is the Coastal Marine time series data from USGS.
