Environmental Determinations Using Absolute Miospore Frequency, Mississippi River Delta
Samples of modern sediments were collected from the main depositional environments of the Mississippi River delta according to a predetermined sampling pattern designed to determine if: (a) differences could be detected among environments and (b) which environments showed differences. The data were analyzed using a nested analysis of variance test and orthogonal comparisons. Significant differences do exist but are not large enough to be clearly definitive of a particular environment.
