Subarctic Zooplankton Spring Bloom Observations from 1987-1989

A subarctic embayment near Alaska was the site for multi-year observations of zooplankton during spring bloom periods from 1987 to 1989. Data was collected twice weekly by the University of Alaska Juneau Center for Fisheries and Ocean Sciences using CalVET and NIO nets with specific mesh sizes. Sampling occurred at three to four stations within the bay and an adjacent inlet.

Use Cases

• Analyzing zooplankton species composition and abundance during spring blooms.
• Studying temporal changes in plankton populations across a multi-year period.
• Comparing catch efficiency between nets with 165-micrometer and 500-micrometer mesh.
• Correlating plankton data with environmental conditions at specific sampling stations.

Strengths

• Data collection followed a consistent, twice-weekly sampling protocol over multiple years.
• Specifies the use of two distinct net types (CalVET and NIO) with precise mesh sizes (165µm and 500µm).
• Sampling was geographically focused on 3-4 stations within a defined subarctic embayment and inlet.

Limitations

• Critical metadata such as column names, row count, file size, and license are unavailable from all sources.
• There is a conflict in the 'last updated' date: one source reports 1989-06-12, while another reports 2026-04-01, suggesting a potential metadata error.
