Data for dissolved organic matter and associated environmental variables across land–water

26 headwater catchments across four regions in Quebec's boreal and boreal-arctic transition zone provide dissolved organic carbon concentrations and composition data. Adrien Simonet compiled this dataset from terrestrial and aquatic compartments during summer sampling campaigns from 2021 to 2024. The data spans a significant latitudinal gradient from 48.9°N to 59.1°N, covering the La Romaine, Eastmain, Peribonka, and George River watersheds.

Use Cases

• Modeling dissolved organic carbon transport from soils to streams based on catchment-scale sampling.
• Analyzing the influence of geographic and climatic variables on organic matter composition.
• Studying spatial and temporal patterns of carbon flux across a boreal latitudinal gradient.
• Comparing organic matter characteristics between terrestrial (upland, riparian) and aquatic (stream, lake) compartments.

Strengths

• Samples were collected across 26 distinct headwater catchments, providing spatial breadth.
• Data covers a four-year time series from 2021 to 2024, captured during consistent summer sampling periods.
• The study area spans a notable latitudinal range from 48.9°N to 59.1°N, encompassing boreal and boreal-arctic transition zones.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Sampling is limited to the summer months (July-August), which may not capture full seasonal dynamics.
