Great Lakes Zooplankton and Chemical Survey 1970-1972

Great Lakes data includes zooplankton, chemical, and other measurements collected from July 1970 to March 1972. The University of Michigan gathered the data using nets and sediment samplers with support from the Great Lakes Project and Seagrant project. This dataset is hosted by NOAA NCEI and appears on multiple government data platforms.

Use Cases

• Analyzing historical zooplankton community composition in the Great Lakes.
• Studying changes in water chemistry parameters over a 20-month period.
• Correlating sediment sampler data with biological and chemical measurements.
• Establishing baseline conditions for Great Lakes ecosystem health in the early 1970s.

Strengths

• Data collection spans a defined 20-month period from July 1970 to March 1972.
• Measurements were collected using standardized instruments like nets and sediment samplers.
• Dataset has cross-platform presence on NASA EarthData and Data.gov, indicating curation and importance.

Limitations

• Specific column names, row counts, and file sizes are not provided by any source.
• There is a conflict in the 'last updated' metadata: one source lists 2026-03-05, another lists 1972-03-01.
• License information is not specified.
