Data underlying the study: Addition of iron does not ameliorate sulfide toxicity by sargassum influx to mangroves but dampens methane and nitrous oxide emissions

This dataset contains the data from a mesocosm experiment studying the impact of Sargassum inundations on red mangrove health, as well as greenhouse gas emissions. The data was collected through an experiment involving sargassum seaweed, iron oxyde powder, and red mangrove saplings, conducted from February to April 2022 at the greenhouse Nergena (Unifarm, Wageningen). Mangroves were exposed to re-hydrated sargassum originating on Bonaire (washed-up) to test the efficiency of Fe addition in preventing S2- accumulation in the sediment porewater and its toxicity to mangroves. GHG fluxes from the mesocosms were also measured.

本数据集涵盖一项中宇宙实验（mesocosm experiment）的全部相关数据，该实验聚焦于马尾藻（Sargassum）大规模暴发对红树（red mangrove）健康及温室气体排放的影响。实验所用物料包含马尾藻、氧化铁粉末与红树幼苗，于2022年2月至4月间在瓦赫宁根大学Unifarm平台的Nergena温室内完成。实验中，研究人员将源自博奈尔岛的冲岸复水马尾藻施加至红树生境，以此测试铁元素添加对抑制沉积物孔隙水中硫离子（S²⁻）积累、以及该离子对红树毒性的缓解效果。本实验同时测定了各中宇宙实验单元的温室气体通量。
