QICS Data: Gene Expression in Scallops and Mussels Near a Sub-Seabed CO2 Release

125-day gene expression data from scallops (Pecten maximus) and mussels (Mytilus edulis) deployed near a sub-seabed CO2 release site in Ardmucknish Bay, Scotland. The dataset includes samples from six time points over the experiment's 37-day injection and recovery phases, contrasted with a reference site. It was produced by the British Geological Survey's QICS project and published in 2015.

Use Cases

• Assessing the impact of elevated pCO2 on ion-regulatory gene transcription based on the described carbonic anhydrase and ATPase genes.
• Comparing temporal gene expression patterns between a CO2-exposed site and a reference site over the described 125-day period.
• Analyzing species-specific physiological responses to environmental stress based on data from two bivalve species.
• Training models to predict molecular ecophysiological impacts from controlled CO2 release experiments.

Strengths

• Data spans a 125-day period with six specific sampling time points.
• Includes a controlled comparison between a CO2 release site and a reference site within the same bay.
• Focuses on two distinct bivalve species, allowing for cross-species analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description indicates no significant gene regulation was found for the targeted genes, which may limit the dataset's utility for certain analyses.
