Input data used to model sediment grain size for the north-west European
continental shelf. Data includes: Sediment groundtruth observations with
measured fractions of mud, sand and gravel, also converted to two additive
log-ratios. These total 45761 samples. Also included are the eight predictor
variables that were used to model sediment grain size. These were: Bathymetry,
Bathymetric position index at a 50-pixel radii, Bathymetric position index at
a 434-pixel radii, Distance from coast, Current speed at the seabed, Wave peak
orbital velocity at the seabed, and suspended inorganic particulate matter for
summer and winter as two separate variables.
