Water Quality and Fish Data from Alaskan National Parks

39 sites across two major Alaskan national parks were sampled for physical and chemical water quality parameters. The National Park Service collected this data during the summer field season from May 21 to September 8, 2003. Observations provide a snapshot of aquatic conditions in Wrangell-St. Elias and Denali National Park and Preserve.

Use Cases

• Analyze spatial variation in water temperature or pH across 39 distinct sampling sites.
• Correlate dissolved oxygen levels with observed fish population data within the parks.
• Model seasonal changes in chemical parameters like nutrient concentrations from May to September.
• Assess water quality compliance against environmental standards for protected Alaskan watersheds.

Strengths

• Data covers 39 distinct sampling locations for spatial analysis.
• Observations span a continuous summer field season from May to September 2003.
• Collected by the authoritative National Park Service for regulatory and scientific purposes.

Limitations

• Dataset is limited to a single year (2003), offering no longitudinal trend analysis.
• Unknown sample size and row count prevents assessment of statistical power.
• Lack of column details obscures the specific chemical and physical parameters measured.
