North Sea benthic C trawled-impacted

Two objects are provided: a sampling stations x variables data frame (csv file) and a raster brick of smoothed values (grd and gri files). csv file. -longitude, latitude: geographic coordinates of the sampling stations (WGS84)-depth: water depth in m-sediment type: qualitative variable, 5 categories from very muddy to very sandy-swepth area ratio: bottom trawling frequency as the number of times an area in trawled (per year)-gear penetration depth: averaged penetration of the bottom trawling gear into the sediment in cm-observed C content: organism carbon content (g C m2) as ash free dry mass (g m2) devided by 2-C carrying capacity: organism carbon content back-calculated prior to trawling disturbance-relative benthic status: ratio of observed organism carbon content by back-calculated content-C loss: back-calculated organism carbon content minus observed content
