An evaluation of the efficacy of shell hash for the mitigation of intertidal sediment acidification
Abstract Our objectives were twofold: (1) to determine whether the addition of shell hash to intertidal sediments would mitigate porewater acidification and (2) whether its effectiveness was dependent on the type of sediment as described by organic matter (OM) and particle grain size (PGS).
