The environmental inputs are extracted from global databases. At the seabed the model's vertical zonation allows for underground (diagenetic) processes, bed granular transport, lower stable framework, upper collapsable framework. This voxelation allows for the carbonate to be placed (accumulated) correctly within the bedding and clast fabrics. The stratigraphy and seabed elevation are built in this way. As conditions change (e.g., by shallowing) the biological communities respond in the simulation, and so too do the production rates and clast/binding arrangements. Events punctuate the record, and the organism assemblages adjust according to frequencies and severities. The population stocks are calculated by diffuse competition in a Lotke-Volterra scheme, or via cellular simulations of close-in interactions to represent competition by growth, recruitment.

No Describe post-processing software Visualization software needed? No If above answer is yes Other visualization software Describe processes represented by the model Population ecology represented by diffuse competition Lotke-Volterra calculus, cellular automaton, cellular stochastic models. Sediment transport arbitrated by slopes and wave energy pickup Bioerosion scaled to the seafloor presence of skeletal material Describe key physical parameters and equations Bathymetry, seawater temperatures, ocean wave climate, benthic irradiance, seafloor hardness Describe length scale and resolution constraints Cells are approximately 1-1000m in scale; map areas 10-100km on side. Describe time scale and resolution constraints Timestepping is usually annual, extending over 1000 years. However the model is capable of doing finer and longer runs. Describe any numerical limitations and issues Usual Python limitations on floating point precision. ODE's are solved on scales much finer than annual, and their performance is monitored. Describe available calibration data sets The model produces virtual core-logs which can be compared with Ocean Drilling Program and other descriptive core logs and with outcrops.
