Each [[depocenter]] has a unique depositional history that reflects the integration of all responses to depositional processes and environmental factors, including [[tectonics]], [[climate]], [[sediment supply]], and [[Sea level cycles and climate|sea level variation]].

Each depocenter has a unique depositional history that reflects the integration of all responses to depositional processes and environmental factors, including tectonics, climate, sediment supply, and sea level variation. These factors result in cycles of deposition: the sediments accumulated during each cycle are the depositional sequence. Integration of multiple data sets, including (1) seismic reflection profiles, (2) biostratigraphic analyses, (3) wireline logs, (4) cores, and (5) detailed measured sections, helps us define the depositional sequences and interpret primary factors affecting formation of each cycle. Precise mapping of each depositional sequence within each depocenter requires careful data integration.
This article discusses the concept of depositional sequences and how to identify them, using a data set from the High Island–East Breaks area. The location of this study area is shown on the depocenter maps of Figures 1 through 4.

Figure 5 is a map of the study area, showing the named offshore exploration areas and bathymetry. It also shows the locations of the East Breaks 160-161 field, illustrated seismic profiles and a reference well.
