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 samples from Northwind Ridge core PI-88AR P5.

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:

Samples numbered 1 through 88 are 10cc samples obtained for lithostatigraphy and biostratigraphy. Samples numbered 89 through 131 are cuttings obtained when paleomagnetics samples were taken and are approximately 10cc.
The samples were washed in distilled water, wet sieved to three size fractions; <62um, 62um - 2mm, and >2mm. The size fractions were dried and weighed. The 62um - 2mm and the >2mm fractions were combined after weighing. The >62um fraction was sieved at 150um and counting splits of 300 - 350 planktic foraminifers were obtained from the >150um fraction using a Carpco sample splitter.
In general, our taxonomic concepts follow Parker (1962, 1967).

Completeness_Report:

Planktic foraminifers were identified, sorted and glued to standard 60 square micropaleontological slides. Benthic foraminifers were also counted. All planktic foraminifers were removed from samples containing insufficient specimens for a counting split.

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 91-346 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 91-346 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.
