Description:

Abstract:

The U.S. Geological Survey recovered 9 piston cores from the Northwind Ridge in the Canada Basin of the Arctic Ocean from a cruise of the USCGC Polar Star during 1988. Preliminary analysis of the cores suggests sediments deposited on Northwind Ridge preserve a detailed record of glacial and interglacial cycles for the last few hundred-thousand to one million years. This report includes quantitative data on foraminifers and selected sediment size-fraction data in 98 samples from Northwind Ridge core PI-88AR P3, 51 samples from core PI-88-AR P7 and 117 samples from core PI-88-AR P9.

Purpose:

These foraminifer data will be the basis for future interpretive studies of the climate history of the Arctic Ocean.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

Included in the attribute data for each sample is the fraction of the original sample from which the specimens were extracted.

Logical_Consistency_Report:

The samples were washed in distilled water, wet sieved to three size fractions; >63um, 63um - 2mm and >2mm. The material from each size fraction was dried at 50 degrees C and weighed. The 63um - 2mm and the >2mm fractions were combined after weighing. The >63um fraction was dry-sieved at 150um. The >150um size fraction of samples with abundant planktic foraminifers was split with a Carpco microsplitter to obtain representative aliquots of 300 - 350 planktic foraminifers. Included in the attribute data for each sample is the fraction of the original sample from which the specimens were extracted.
In general, our taxonomic concepts follow Parker (1962, 1967).

Completeness_Report:

All foraminifers >150um were removed and counted from samples which contained less than 350 planktic foraminifers.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:

Although horizontal position of thes cores is given to the nearest 0.01 minute of latitude and longitude, no information is presented in OFR 93-218 or in OFR 92-426 indicating the magnitude of likely errors in the core locations.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report:

Core intervals sampled are indicated in the attribute data to the nearest 0.1 cm, but there is no information in OFR 93-218 or OFR 92-426 concerning the fidelity of depth in core to depth below the sea floor. The samples were taken from piston cores; there is no indication that information from trigger cores or box cores was included.

Process_Step:

Process_Description:

The samples were washed in distilled water, wet sieved to three size fractions; >63um, 63um - 2mm and >2mm. The material from each size fraction was dried at 50 degrees C and weighed. The 63um - 2mm and the >2mm fractions were combined after weighing. The >63um fraction was dry- sieved at 150um. The >150um size fraction of samples with abundant planktic foraminifers was split with a Carpco microsplitter to obtain representative aliquots of 300 - 350 planktic foraminifers. Foraminifers were sorted, identified and glued to standard micropaleontological slides and data were used to calculate abundances. All foraminifers >150um were removed and counted from samples which contained less than 350 planktic foraminifers. These data were used for planktic census and abundance estimates.
