Short summary
A workflow for sampling hard rock cores for microbiological research was developed and optimized during International Ocean Discovery Program (IODP) Expedition 399. These procedures and protocols were adapted from previous expeditions and further optimized for handling large numbers of hard rock samples. The workflow is also intended to facilitate interdisciplinary collaborations so as to maximize the scientific value of each sample for the whole scientific team.
