See DEMOS Laboratory for a screenshot demonstration of planned tools.
The pointers below presently link to publically available software and executable modules with visualization and analysis elements under consideration for the future CHRONOS-Climate Cycles online visualization and analysis toolkits.
(1) Visualize
 CHRONOS Age-Depth Program (ADP)-plots age-depth data, and allows interactive fitting of a line of correlation or age model. [Requires Java.]

[Runs on UNIX, LINUX.]
Gnuplot--a portable command-line driven interactive plotting utility. In 2D, it draws line, point, dot, box, histogram graphs or vector fields; in 3D, line, point and dot surfaces, color or grayscale surfaces [For UNIX, IBM OS/2, MS Windows, DOS, Apple Macintosh, VMS, Atari and many other platforms.]
PanPlot--a visualization tool for the information system PANGAEA. It can be used as a stand-alone application or started automatically by the information system to plot data versus depth or time or in a ternary view (Pangaea Network). [For Mac and Windows.]
Core Log Integration Platform--a set of graphic, interactive data analysis products for depth-merging and integrating core and downhole log data (Lamont-Doherty Earth Observatory). [Runs on Sun workstations using Solaris and the OpenWindows, Motif (mwm), or CDE (dtwm) window managers.]
