Sea level changes may be graphically illustrated utilizing ecologs, which are constructed by plotting paleobathymetric well data against depth in a well. Theoretically, each ecolog cycle is the result of the interaction of eustacy and regional vertical movements. Although ecologs are generally used to illustrate changes in sea level, they can be used for stratigraphic correlation. Differences in ecolog cycles among wells may be just as important as their similarities. In theory eustacy is a constant that can be substracted from relative sea level change to delineate regional vertical movement. During the Neogene, oxygen isotope ratio cycles represent a record of paleoglaciation and, therefore, eustacy. Therefore, oxygen isotope ratios may be used in conjunction with ecologs to distinquish between eustatic events and regional vertical movement in Neogene stratigraphic sections.
