What is EPIC? EPIC is many things all designed to work with in situ data sets. For the researcher, EPIC provides a large selection of high quality analysis tools for many different types of data (time series, CTD, ADCP, XBT, bottle, etc.). For the programmer, it provides a single application program interface (C, Fortran, and MATLAB) to multiple data formats (netCDF, Classic EPIC, and hpf format). For the database manager, it provides tools for the loading of meta data into a database and formatting the results from a researchers query into a format that can be directly used by the EPIC analysis tools. For the webmaster, EPIC provides a set of tools to access and display data in real time.
