Global marine and estuarine mangrove distribution in 2020

This is the product generated from the research entitled with 'A global assessment of mangrove soil organic carbon sources and implications for blue carbon credit.'The mapping of estuarine and marine mangroves contains two steps, the mapping of global mangroves and the mapping of estuarine regions. The Global Mangrove Watch datasets are the most commonly used mangrove datasets with public access. Therefore, we extracted the global mangrove distribution in 2020 from Global Mangrove Watch. For the estuarine region mapping, we applied a mask of the global estuary distribution developed by Sea Around Us project to mangrove distribution . However, we noticed that the estuary distribution only convers the water, while mangroves around the estuary was overlooked. We therefore combine the estuary distribution with the sampling point in our collection which was clearly defined as estuarine mangroves to manually draw the boundaries between estuarine and marine mangroves.

本数据集源自题为《全球红树林土壤有机碳来源评估及其对蓝色碳汇信贷的启示》的研究。河口与海洋红树林的制图流程包含两个环节：全球红树林分布制图与河口区域制图。全球红树林观测（Global Mangrove Watch）数据集是当前应用最为广泛的公开红树林数据集，因此我们从该数据集中提取了2020年的全球红树林分布数据。在河口区域制图环节中，我们将「海洋环绕我们（Sea Around Us）」项目开发的全球河口分布掩码应用于红树林分布数据。但经分析发现，该河口分布数据仅覆盖水域范围，河口周边的红树林未被纳入覆盖范畴。为此，我们将河口分布数据与本研究收集的、明确界定为河口红树林的采样点相结合，手动划定了河口红树林与海洋红树林的边界。
