A marine heat wave drives massive losses from the world’s largest seagrass carbon stocks

The database compiles published data (in Arias-Ortiz et al. 201X, Nature Climate Change, in press) on biogeochemical characteristics (density, organic carbon, stable carbon isotopes and sediment grain size) of soils underneath seagrass meadows in Shark Bay, Western Australia. Pb-210 concentrations of the first 20 cm are included along with C-14 raw ages. The dataset compiles data for a total of 49 cores, 25 - 300 cm-long (11 cores with Pb-210 data and C-14 data).
