artifact description
A group of samples taken from various units in a drill hole at the base of the sea cliffs, about 1½ miles south of Barrow Village, Northern Alaska, have been examined to determine their foraminiferal content. Application of recent knowledge of foraminiferal distribution and ecology served to point out that possible depth changes can be observed in the fossil assemblages. Correlation of these assemblages with existing particle size distribution data to determine paleoecological conditions reveals that the sediments were deposited in relatively shallow water under open-ocean, nearshore conditions and exhibit a shoaling-innundation relationship within the units represented. Temperatures during this time appeared to become progressively colder. No pelagic genera or arenaceous forms were found in the samples investigated.
