Hourly in-situ measurements and derived quantities from a macroalgal reef at Helgoland, Germany (54.18°N, 7.88°E), spanning the full annual cycle of 2025. Variables include sea-surface temperature, salinity, dissolved oxygen, photosynthetically active radiation, wind speed, and water and atmospheric partial pressures of CO₂ and CH₄. The dataset was authored by Bryce Van Dam and includes a second file with hourly gross production, respiration, and net ecosystem metabolism estimates derived from dissolved oxygen.
Use Cases
- Modeling coastal carbon dioxide and methane fluxes based on hourly pCO₂ and pCH₄ measurements.
- Analyzing the relationship between environmental drivers (e.g., temperature, PAR, wind speed) and ecosystem metabolism (P, R, NEM).
- Studying the seasonal dynamics of a macroalgal reef's greenhouse gas exchange over a full annual cycle.
- Validating or calibrating biogeochemical models for coastal ecosystems using high-frequency in-situ data.
Strengths
- Full annual cycle of 2025 provides complete seasonal coverage.
- Includes both direct measurements (e.g., temperature, pCO₂) and model-derived ecosystem metabolism estimates (P, R, NEM).
- Hourly temporal resolution allows for analysis of diel and short-term variability.
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.
- Data may reflect geographic bias inherent to a single site at Helgoland.
