Description
The goal of the study was to evaluate how a newly re-established mussel farm in As Vig, Denmark, affected the sediment-water nutrient exchange. A mussel farm and a reference site were sampled on four occasions in two years, spanning the entire first year of production. Nitrate reduction rates and sediment-water fluxes of nutrients, methane, dissolved inorganic carbon and oxygen were measured in situ with benthic chamber landers. Sediment cores were collected for measurements of carbon, nitrogen and pigments and sedimentation rates were measured with sediment traps. Currents, illuminance at the seafloor and water column profiles of salinity, temperature and chlorophyll a were measured to describe the environmental characteristics of the stations.
The dataset contains 8 files with the following data:
- CTD profiles and chlorophyll a concentrations in the water column
- Current speed and current directions
- Illuminance at the sediment surface
- Sedimentation rates (total, organic matter, inorganic matter)
- Sediment-water fluxes of oxygen, nutrients, methane and dissolved inorganic carbon
- Nit
