Eastern Canada Diatom Index Station Classifications Since 1935

Station locations are classified according to the Eastern Canada Diatom Index (IDEC). Data originates from benthic diatom sampling conducted since 1935 and has been converted to version 3 of the index. The dataset provides information on environmental conditions in rivers based on diatom community composition.

Use Cases

• Analyze station location classifications to map spatial patterns in river health across Eastern Canada.
• Study changes in diatom community composition over time using data collected since 1935.
• Apply the IDEC version 3 index to assess environmental conditions and pollution sensitivity in aquatic ecosystems.
• Correlate station classifications with prevailing environmental conditions described by the diatom species data.

Strengths

• Contains data obtained from sampling stations since 1935, providing long-term temporal coverage.
• Data is classified using a standardized scientific index (IDEC version 3).
• Focuses on benthic diatoms, which are recognized bioindicators for river environmental conditions.

Limitations

• Specific sample size, row count, and column details are unknown.
• Data relies on an automated translation of third-party metadata, which may introduce inaccuracies.
• The dataset's spatial granularity is limited to station locations without detailed environmental measurements.
