Tributary Benthic Invertebrate and Water Quality Data for Oil Sands Region, 2011-2017

Environment and Climate Change Canada provides biomonitoring data on benthic macroinvertebrates and supporting water chemistry from tributaries of the Lower Athabasca River in the oil sands region. The dataset includes measures of nutrients, metals, polycyclic aromatic hydrocarbons, and major ions collected from over 100 sites between fall 2011 and fall 2017. An interpretive report analyzing data from 2012-2015 was released in 2018.

Use Cases

• Assessing aquatic ecosystem health based on benthic macroinvertebrate assemblage composition.
• Modeling relationships between catchment disturbance, PAC concentrations, and biological communities.
• Comparing sampling method effectiveness (kick net vs. Hess) for taxonomic resolution in monitoring programs.
• Developing Reference Condition Approach models to detect divergence from baseline ecological conditions.

Strengths

• Data collection spans 6 years (fall 2011 to fall 2017), providing a multi-year time series.
• Spatial coverage includes over 100 sites on major tributaries and up to 21 sites on the Athabasca River mainstem.
• Includes multiple analyte groups: nutrients, metals (dissolved and total), polycyclic aromatic hydrocarbons, and major ions.
• Linked to a peer-reviewed interpretive report (Culp et al., 2018) providing analysis and context.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• Description metadata is limited; actual data quality requires manual inspection after download.
