Cyanobacterial Bloom Monitoring At Alberta Beaches

Alberta Health and Alberta Health Services began seasonal monitoring for cyanobacterial blooms at high-use recreational beaches in 2009. The dataset contains water sample records organized into two files for bloom indicators and individual species counts, updated monthly from June to September. Data from the current year is considered preliminary pending further quality control.

Use Cases

• Correlate cyanobacterial species counts with key bloom indicator levels to identify toxin-producing conditions.
• Analyze temporal trends in bloom indicators across different Alberta beaches to identify seasonal patterns.
• Train models to predict advisory issuance based on historical water sample data and visual inspection records.
• Assess the relationship between supporting data columns, like nutrient content, and the presence of specific cyanobacteria species.

Strengths

• Data collection follows the standardized Alberta Safe Beach Protocol, ensuring consistent methodology.
• Monitoring has been conducted seasonally since 2009, providing a multi-year time series.
• Dataset is updated monthly during the active monitoring season (June-September).

Limitations

• Rows and sample size are unknown, limiting assessment of statistical power.
• Data for the current year is flagged as preliminary and subject to change.
• Geographic coverage is limited to recreational beaches in Alberta, Canada.
