Importance of habitat selection for Blue Carbon projects: Doubtful additionality in a seagrass case study

The database compiles published data (in Lafratta et al. 201X, Biology Letters, submitted) on biogeochemical characteristics (density, organic carbon, stable carbon isotopes and sediment grain size) of soils underneath seagrass meadows in False Bay, South Australia. Pb-210 concentrations of the first 12-20 cm are included. The dataset compiles data for a total of 12 cores, 80-140 cm-long (5 cores with Pb-210 data, 4 cores with sediment grain size).
