Predictor variables and groundtruth samples for north-west European continental shelf quantitative sediment analysis

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.

本数据集用于构建西北欧大陆架的沉积物颗粒尺寸模型。数据包含：沉积物真值观测数据，包括泥、沙和砾石的比例测量值，并已转换为两个加性对数比率。总计45761个样本。此外，还包括用于构建沉积物颗粒尺寸模型的八个预测变量，具体为：水深、以50像素半径计算的水深位置指数、以434像素半径计算的水深位置指数、离岸距离、海底流速、海底波峰轨道速度，以及夏季和冬季的悬浮无机颗粒物，作为两个独立的变量。
