The Age-Depth window is arranged so that biostratigraphic and or paleomagnetic age-depth control information are plotted in the right window. The user can select or deselect which kinds of age control data are plotted by clicking on the stratigraphic data type (e.g. "nannofossils").
The stratigraphic data can be plotted as either MCD depth vs. Age or MBSF depth vs. age by selecting the appropriate button beneath the plotting window. The stratigraphic datums are plotted as vertical bars, representing the depth ranges for each datum.

Constructing an Age Model
The user can define an age model (age, depth control) for a given spliced data record using the "Construct Age Model" button in the Age Modeling window.
The Age Modeling window is arranged so that biostratigraphic and or paleomagnetic age-depth control information are plotted in the right window. The user can select or deselect which kinds of age control data are plotted by clicking on the stratigraphic data type (e.g. "nannofossils").
The stratigraphic data can be plotted as either MCD depth vs. Age or MBSF depth vs. age by selecting the appropriate button beneath the plotting window. The stratigraphic datums are plotted as vertical bars, representing the depth ranges for each datum.
To construct an age model, click on a selected datum label with the CENTER mouse button (not the actual point which is beneath it). The age-depth datum is then added to a list on the left side of the window. A line is drawn from the 0-0 age-depth position to this datum. The user can then add to the age model by selecting another datum. The user can also explore the Age-Depth plot locations by depressing the LEFT mouse button and viewing the stratigraphic information in the dialog box below.
User-defined age-depth control points can be entered into the age model datum list by typing in the "depth" and "age" dialog boxes and clicking the "Add hand pick..." button.
Age control points can be removed by clicking on the datum label in the list and then clicking the "Remove datum..." button directly below. This removes the datum from the list and updates the age-depth plot and the Splice time series plot (if opened).
