Predicted seabed mud content in the north-northwest region of the Australian continental EEZ 2013

This dataset provides the spatially continuous data of predicted seabed mud content (sediment fraction finer than 63 µm) expressed as a weight percentage ranging from 0 to 100%, presented in 0.0025 decimal degree (dd) resolution raster grids format and an ascii text file. The dataset covers the north-northwest region of the Australian continental EEZ. This dataset supersedes previous predictions of seabed mud content for the region with demonstrated improvements in accuracy. Accuracy of predictions varies based on density of underlying data and level of seabed complexity. Artefacts occur in this dataset as a result of insufficient samples in relevant areas. This dataset is intended for use at regional scale. The dataset may not be appropriate for use at local scales in areas where sample density is insufficient to detect local variation in sediment properties. To obtain the most accurate interpretation of sediment distribution in these areas, it is recommended that additional samples be collected and interpolations updated.

本数据集提供了海底泥质含量（粒径小于63微米的沉积物占比）的空间连续预测数据，以重量百分比表示，取值范围为0至100%。数据集采用0.0025十进制度（decimal degree, dd）分辨率的栅格网格格式与ASCII文本文件进行存储。本数据集覆盖澳大利亚大陆专属经济区（Exclusive Economic Zone, EEZ）的北北西海域，替代了该区域此前的海底泥质含量预测成果，且经证实其预测精度有所提升。预测精度会随基础数据的密度以及海底复杂程度的差异而变化。由于相关区域采样样本不足，本数据集存在伪影。本数据集适用于区域尺度的研究应用，在采样密度不足以探测沉积物属性局地变化的区域，本数据集不适用于局地尺度的应用。若要获取这些区域沉积物分布的最精准解译结果，建议补充采集样本并更新插值方案。
