Riverbed Nitrogen Transformations in the Hammer Stream, UK

Environmental Information Data Centre provides in situ field measurements of riverbed nitrogen transformations in the Hammer Stream, UK. Data include baseline concentrations of nutrients, chloride, oxygen, pH, temperature, Fe(II), organic carbon, 15N-N2, methane, and nitrous oxide sampled from porewater. Measurements were performed in November 2014 and February, April, and July 2015.

Use Cases

• Analyze correlations between nutrient concentrations (NO2, NO3, NH3, PO4) and environmental variables like pH and temperature.
• Model nitrous oxide (N2O) and methane (CH4) production as a function of organic carbon and Fe(II) levels in porewater.
• Assess seasonal variation in nitrogen transformations using data from four distinct sampling months in 2014-2015.
• Investigate the relationship between chloride levels and other baseline nutrient concentrations in a sandy tributary.

Strengths

• Data collected during four distinct seasonal campaigns (November 2014, February, April, July 2015).
• Includes multiple measured analytes: nutrients, gases (CH4, N2O), and physicochemical parameters (pH, temperature).
• Focus on in situ measurements from a specific sandy tributary (Hammer Stream, UK).

Limitations

• Limited temporal scope to four months over a single year, lacking long-term trend data.
• Geographic scope is restricted to a single stream in Hampshire, UK, limiting generalizability.
• Sample size and row count are unknown, potentially constraining statistical power.
