Long-term reorganization of ocean nutrient distribution

Oceans rely on nutrients like nitrate and phosphate to support the growth
of phytoplankton and marine productivity. Using nearly a century of global
ocean data, this study shows that nutrients are changing in different ways
depending on location. This entry contains scripts needed for data
analysis presented in this manuscript, as well as the nutrient data files.
The data analysis consists of four parts: (i) preprocessing, (ii)
estimating long-term surface nutrient trends, (iii) estimating vertical
trends and their significance, and (iv) analysis of CMIP6 data. The data
consists of the pre-processed World Ocean Database observations.

海洋依赖硝酸盐、磷酸盐等营养盐维系浮游植物生长与海洋生产力。本研究基于近百年全球海洋观测数据，揭示了不同海域营养盐的变化模式存在显著差异。本数据集包含本文研究中数据分析所需的代码脚本，以及配套的营养盐数据文件。数据分析共分为四个模块：(i) 数据预处理；(ii) 表层营养盐长期变化趋势估算；(iii) 垂向变化趋势及其显著性检验；(iv) CMIP6（Coupled Model Intercomparison Project Phase 6）数据分析。本数据集所用数据为经预处理的世界海洋数据库（World Ocean Database）观测资料。
