To more effectively use paleoecology in support of E & P, basic information about the environmental tolerances and preferences of microfossils must be readily available. Paleoecological information, such as oxygen and salinity tolerances, sediment preferences, presently are not easily accessed.

Because of frequent down-gradient sediment displacement paleobathymetric estimates based upon benthic foraminifera have primarily used the upper-depth limits of species. However, lower bathyal and abyssal deposition occurs below the upper-depths limits of most benthic foraminifera, making existing paleobathymetric models of little use in resolving bathyal or abyssal paleo-water depth trends or in separating autochthonous and allochthonous components.

As much as possible we eliminated the random or imprecise occurrences in favor of more repeatable signal, therefore the analysis focused on those taxa that have the robust and repeatable occurrences. A secondary objective in reducing the number of taxa in the analysis was to make the analysis more manageable and lessen the likelihood that useful patterns will be obscured by spurious patterns that are noise.
