Dataset for Intertidal Organic Carbon Stocks in Central Jiangsu

This dataset supports the research article titled "Spatial distribution of organic carbon stocks in intertidal bare-flat sediments based on a cascading remote sensing inversion approach." It provides a comprehensive collection of field-measured sediment parameters and vertical profile data from the intertidal bare flats of the Central Jiangsu coast (specifically the Radial Sand Ridge system). The dataset includes: 1.Field Survey Data: Geographic coordinates (latitude and longitude) for sampling sites across 14 representative transects. 2.Sediment Physical Properties: Measured values for mean grain size (MZ), moisture content (MC, %), bulk density (BD), and sediment organic carbon content (OC).Vertical Profile Information: Layered sediment data (0–10, 10–20, 20–30, 30–40, and 40–50 cm) used to characterize the vertical distribution of organic carbon density (IOCD). 3.Validation Metadata: Observed values used for the calibration and validation of the Sediment Organic Carbon Stock Cascading Remote Sensing Inversion Framework (SOCS-CRIF).These data were used to estimate a total organic carbon stock of 7.76*10^5 t for the 0–50 cm sediment layer in the study area.

This dataset is essential for researchers focused on blue carbon assessment, coastal geomorphology, and remote sensing applications in muddy tidal environments.
