Mangrove soil biogeochemistry and geomorphology data from Biscayne National Park, Florida, USA, 2011 - 2024

We quantified long-term changes in tidal hydrology and surface soil elevation (2011-2024) across two representative fringe mangrove forest sites (BISC-1, BISC-2) in Biscayne National Park (Florida, USA). We measured the spatiotemporal variation of monthly wrack deposition, litter breakdown rates, soil organic carbon, and stable isotope δ13C and δ15N content along landward transects in Biscayne National Park (Florida, USA) from 2022 to 2024. We surveyed marine wrack deposition biovolume monthly using a quadrat in plots along our transects. At each marine wrack survey plot, we collected soil cores seasonally to measure soil physicochemistry. Finally, we deployed leaf litter decomposition mesh bags with Rhizophora mangle leaf litter, Thalassia testudinum leaf litter, and teabag standards to quantify breakdown rates on the soil surface of each marine wrack survey plot. Data collection is complete.

本研究量化了美国佛罗里达州比斯坎国家公园（Biscayne National Park）内两处代表性潮缘红树林（fringe mangrove forest）样地（BISC-1、BISC-2）2011年至2024年的潮汐水文与表层土壤高程长期变化。2022年至2024年，本研究在该公园内沿向陆样带，测定了月度海漂碎屑（wrack）沉积量、枯落物分解速率、土壤有机碳含量以及稳定同位素δ¹³C与δ¹⁵N的时空变化特征。本研究沿样带布设样方（quadrat），每月调查海漂碎屑沉积的体积量。在每个海漂碎屑调查样地中，我们按季节采集土芯以测定土壤理化性质。最后，本研究在每个海漂碎屑调查样地的土壤表面布设装有美洲红树（Rhizophora mangle）枯落物、海龟草（Thalassia testudinum）枯落物以及茶袋标准基质的叶枯落物分解网袋，以量化分解速率。本数据集的野外数据采集工作已全部完成。
