Mainstem Benthic Invertebrates, Oil Sands Region

The Joint Canada-Alberta Implementation Plan for Oil Sands Monitoring (Environment Canada and Alberta Environment 2012) included the initiation of new biomonitoring sites on the Lower Athabasca River mainstem and its major tributaries following the study designs proposed in the Integrated Monitoring Plan for the Oil Sands (Phase 2) (Environment Canada and Alberta Environment 2011).

This data consists of samples of benthic macroinvertebrates, comprised of insects, crustaceans, molluscs, and worms that represent a group of organisms used widely in environmental monitoring programs as indicators to assess the effects of water quality or physical habitat conditions on aquatic ecosystem health. These data are from the Mainstem Athabasca River located in the Athabasca Oil Sands Region of northeastern Alberta, Canada. An interpretive report (Culp et. al., 2018) was released in 2018 that included assessments of the benthic and supporting data from 2012-2015. The full report can be found online at https://open.alberta.ca/publications/9781460140314. The benthic macroinvertebrate data consists of individual, 3-minute traveling kick-net samples using a 400 µm mesh net (Environment Canada 2012a) that were collected in the fall from 2012-2022. No benthic macroinvertebrate samples were collected in 2020 due to the SARS-CoV-2 pandemic. Samples were sorted according to CABIN laboratory protocols (Environment Canada 2012b) and subsampled using a Marchant box. Where possible, the sorted benthic macroinvertebrates were identified to lowest practical taxonomic level, and the total number of organisms for each taxon per 3 minutes sample is provided. Benthic macroinvertebrate data was collected at up to twenty-one sites on the mainstem of the Athabasca River focusing on near-shore gravel and sand habitats on the Athabasca River.

In addition to collecting benthic macroinvertebrate samples, supporting water and sediment chemistry samples were taken at the same sites and on the same dates in the fall 2012-2022. No water or sediment chemistry data was collected in 2020 due to the SARS-CoV-2 pandemic. The data include measures of nutrients, metals (dissolved and total), polycyclic aromatic compounds, major ions, and physical measures. These water and sediment quality samples were collected as per the Phase 1 parameter lists and submitted to CALA accredited analytical laboratories. Taken together, this data uses an integrated approach to assess aquatic ecosystem health of the Athabasca River in response to oil sands development in northeastern Alberta, Canada.
