Abstract
The primary objective of this work is to test the hypothesis that sedimentary and geomorphic settings explain much of the variability in mangrove soil N stocks and burial rates across the world’s mangroves, a concept with direct implications for nutrient removal and impetus for increased focus on co-benefits of blue nitrogen and blue carbon conservation strategies (e.g. ecosystem design features, wastewater treatment, restoration).
We utilized a spatially-explicit global mangrove typology model combining sedimentary and geomorphic settings (SGS) following Worthington et al. (2020) to estimate and compare magnitudes and differences in total nitrogen (TN) stocks and burial rates. An SGS represents a pairing of sedimentary (carbonate, terrigenous) and geomorphic (delta, estuary, lagoon, open coast) settings.

Description of the data and file structure
This dataset includes the following subsections: the conversion data, the nitrogen:phosphorus ratios data, the total nitrogen stocks data, and the total nitrogen burial rates data. The conversion data establishes the relationships between organic carbon and total nitrogen (TN) for each sedimentary setting (carbonate or terrigenous) and sedimentary-geomorphic setting (SGS; terrigenous delta, terrigenous estuary, terrigenous lagoon, terrigenous open coast, carbonate estuary, and carbonate open coast). The N:P ratios are primarily derived from Li et al., (2023) with additions from the authors of this manuscript. The N:P ratios are paired to sedimentary setting. The TN stocks and burial rates data include data from the Coastal Carbon Atlas and Library, directly observed TN stocks and TN burial rates, and data from Wang et al. (2021) and Breithaupt and Steinmuller (2022).

Description: Organic carbon burial rates were compiled by combining two datasets (Breithaupt & Steinmuller, 2022; Wang et al., 2021) and adding any additional observations of OC burial rates published since 2022, which were identified through keyword searches. A second literature search via Web of Science was conducted with keywords ’mangrove’, ’soil’, ’nitrogen’, and ’burial’ to identify studies that either a) stated a TN or N burial rate or b) contained the parameters necessary for the calculation of an N burial rate.
