----- DISPLAY -----

The main window of the Splicer program is divided into two main panel areas. The left-hand panel is the "Composite" panel, whereas the right-hand panel is the "Splicing" Panel.

The DISPLAY OPTION allows the use to change the scaling of the depth axis (Vertical) and the Variable Axis (Horizontal). Changing these parameters affects both the Composite and Splice panel data.

The user can also select to display just the Raw data, the Smoothed data (if smoothing was done), or both Raw and Smoothed data.

The Scroll option allows the user to use the scroll bar to continuously depth-scroll through the data. When this option is turned off, dragging the scroll bar will not continuously depth-scroll the data (improves performance on slower machines).

----- VIEW DEPTH OFFSETS -----

The DEPTH OFFSET pop-up window shows the depth offset value (in meters) which must be applied to the drilling depths (mbsf) in order to optimally align all cores from every hole at a given site. Each DEPTH OFFSET value refers to the depth increment which must be added to (or subtrated from) each core so that a composite spliced record can be constructed.

The DEPTH OFFSET values typically increase with increasing depth, reflecting the fact that they are cumulative depth corrections determined for each core.

The Percent Increase value reflects the percentage by which the Composite Depth Scale (mcd) has increased by relative to the Drilled Depth Scale (mbsf). Spliced composite records derived from pelagic deep-sea sediments are commonly ~8-10% longer than the raw drilling depths due to elastic rebound of sediments during core recovery and handling (see Moran et al., ODP Leg 154 Scientific Results Volume).
