High-frequency monitoring data for the Lena River, the second largest Arctic river, collected near the Samoylov Island Research Station. The dataset likely contains biogeochemical variables, including dissolved organic matter, to observe changes in matter transport due to warming and permafrost thaw. It was produced by Bennet Juhls of the Alfred-Wegener-Institut Helmholtz-Zentrum für Polar- und Meeresforschung.
Use Cases
- Modeling dissolved organic matter (DOM) re-mobilization from permafrost based on biogeochemical variables.
- Analyzing seasonal changes in Arctic river water chemistry based on high-frequency sampling.
- Studying the impact of warming and shifting hydrological regimes on matter transport in the Lena River catchment.
Strengths
- Sampling conducted at high frequency throughout the entire year.
- Focuses on the Lena River, whose catchment has 71% continuous permafrost.
- Data collection enabled by a research station operating year-round.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and file formats are unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
