Full description

The dataset contains raster files (.grd) for environmental and biological variables averaged across a five year time-period before (2005-2009) and after (2011-2016) the calving of the Mertz Glacier Tongue in 2010.

The following data are included:
- surface-chlorophyll-a in summer (in mg/m^3)
- sea-ice concentrations in spring and summer (concentration in %)
- sinking, settling and horizontal flux of food-particles along the seafloor (relative number of particles per grid-cell)
- ocean current speeds at the seafloor (current speed, mean current speed, tidal current speed) (in m/s)
- suspension feeder abundances and standard deviation of the predicted distribution (in %-cover)

Detailed information on how each parameters was generated can be found in the paper:
Jansen et al. (2018) Mapping Antarctic suspension feeder abundances and seafloor-food availability, and modelling their change after a major glacier calving. Frontiers in Ecology and Evolution
