Copepod Abundance Records from Arctic Ocean Ice Stations 1970-1975

A collection of 6,999 records detailing copepod abundances sampled from the Canadian Basin of the Arctic Ocean. Data originates from Clarence Greer Pautzke's PhD dissertation and was collected at Fletcher's Ice Island (T-3) from January 1970 to April 1972 and at the AIDJEX station from June to September 1975.

Use Cases

• Analyze temporal trends in copepod abundance between the 1970-1972 and 1975 sampling periods.
• Compare species composition and density data collected using different net types (2m-square closing net vs. 1m conical net).
• Correlate copepod abundance records with other environmental parameters like chlorophyll a or seawater analysis from the broader study.
• Investigate spatial and seasonal distribution of zooplankton under Arctic pack ice during the specified years.

Strengths

• Contains 6,999 individual abundance records.
• Samples collected over two distinct multi-year campaigns (1970-1972 and 1975).
• Data is part of a larger, documented PhD dissertation and technical report series.

Limitations

• Sample dates may not be continuous, with potential gaps in the analyzed record.
• Data is temporally stale, with the last collection occurring in 1975.
• Sampling methodology and net specifications changed between the two collection periods, complicating direct comparisons.
