A centennial-scale data of suspended particulate matter over the global ocean

The century-scale global dataset of marine suspended particulate matter integrates long-term observations and modeling data, revealing the evolving patterns in concentration, distribution, and composition of SPM. It provides critical evidence for understanding the combined impacts of natural climate variability and human activities. This dataset not only supports research on ocean carbon cycling and ecological modeling but also offers scientific foundations for international pollution governance and ecological conservation policies through analyses of microplastic pollution and mineral distribution in hydrothermal activity zones.
