| Summary: | Fifty-three species of recent benthic foraminifera and thecamoebians have been documented and described from the Breton and Stake Islaand area, northern Gulf of Mexico, and from a core from Barataria Basin, Mississippi delta. Cluster analysis of benthic assemblages using presence/absence and transformed abundance data reveals the presence of a marsh and shallow water marine biofacies. Based on the results of a presence/absence cluster analysis, the shallow water marine biofacies can be subdivided into a miliolid biofacies am an Ammonia beccarii/Elphidium species biofacies. Cluster analysis of transformed abundance data, however, shows that the shallow marine biofacies can be subdivided into four biofacies: a miliolid biofacies, an Ammonia beccarii/Elphidiurm species biofacies, an Elphidiurn species/ Ammonia beccarii/ biofacies am an Elphidiurm gunteri biofacies. The marsh biofacies is restricted to Breton Island, the Ammonia beccarii/ Elphidiurm species biofacies is restricted to the forebar locality of ... |
