Abstract
The stratigraphic distribution of Foraminifera in the
Inner Miramichi Bay is described and compared to surficial
paleontologic data reported by Bartlett (1966), Tapley (1969)
and Scott et al (in press) from the same estuary. Three
major assemblage zones presently occupy the stratigraphy of
Inner Miramichi Bay: the transitional, marginal marine, and
marsh foraminiferal assemblage zones. A marginal marine assemblage
existed in surficial sediments during the field investigations
conducted by Bartlett (1966) and Tapley (1969).
These sediments have since been covered by 20 em. of mud
supporting a transitional faunal assemblage.
The vertical distribution of Foraminifera in the Inner
Miramichi Bay was studied by means of statistical analyses
of data extracted from 11 short gravity cores. A comparison
of cluster analyses yield minor gradations existing within
the limits of distinct assemblage zones. These gradations
were resolved through an intuitive interpretation of the
original data.
