Abstract:

Vertical profile of porewater database provides vertical porewater profiles from peatland sites, detailing chemical, physical, and diffusion-related parameters across measured depths. Site-level information includes site name, country, peatland type, hydrological status, and sampling date. Depth-specific measurements include soluble reactive phosphorus (SRP) and ammonium (NH₄⁺-N) concentrations, pH, and additional notes where relevant.

The dataset further provides parameters used to estimate diffusion, including molecular diffusion coefficients for phosphorus and ammonium at 25 °C, temperature, water content, water density, dynamic viscosity, peat density, loss-on-ignition (LOI), and calculated porosity. Recalculated diffusion coefficients for SRP and NH₄⁺ under in-situ temperature and peat conditions are also given (cm²/s).
