Organic carbon decomposition in rhodolith bed sediment under future climate change projections using the teabag index
Organic carbon decomposition was measured in rhodolith beds using the Teabag Index (TBI; Keuskamp et al., (2013; https://doi.org/10.1016/j.ecolind.2022.109077). The data includes measurements relating to carbon decomposition including mass loss, organic carbon loss, decomposition rate (k) and stabil...
