Environmental data layers for a 5 year period before and after the calving of the Mertz Glacier Tongue

Published: 2018-03-23

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
