Description

The data consists of comprehensive species lists of benthic macrofauna collected as part of environmental monitoring surveys conducted by Akvaplan-niva from aquaculture farms (data are from reference stations at least 1km distance from farms). The data were analyzed to assess large scale patterns across Norwegian fjords as part of Sen et al., 2022 (Estuarine, Coastal and Shelf Science).

Sampling Description

Study Extent

Norwegian fjords (locations at least 1km distance from aquaculture farms).

Sampling

Van Veen grabs were used for collecting sediment samples for measuring enviromental parameters and quantifying benthic macrofaunal communities. CTD was used for water measurements.

Method steps

CTD casts were taken for measuring water temperature,depth, salinity, and oxygen concentration. Sediment samples were collected with a 0.1 m2Van Veen grab. One grab was used for measuring sediment environmental parameters which consisted of pH, percent pelite (sediment fraction <63μm), total organic carbon (TOC), nitrogen (TN) and phosphorus (P) content, and concentrations of the heavy metals zinc (Zn) and copper (Cu). Two replicate grabs (in some cases only one) were taken for macrofauna: sediment was sieved over 1mm mesh and preserved in 4% formaldehyde and identifications were made to lowest possible taxon (usually species) at the Akvaplan-niva lab.
