Standardized Protocol for Soil Survey and Archaeological Diagnosis for the DOPAMICS Research Program v1

We describe the protocol developed as part of the ERC-funded DOPAMICS research program for palm sampling in three forested pre-Columbian sites in French Guiana: MC87 near Régina, the "Grand plateau" in the CNRS Nouragues Research Station, and Mont Galbao near Saül. This protocol follows the setting-up of the research transect (see "before start" section). It aims to carry out an extensive soil survey and archaeological diagnosis. This protocol is made open access under the Creative Commons Attribution License (CC-BY). It details the sampling strategy and steps, and the material needed with the aim to encourage future reuses of this protocol for the same or similar research purposes, and to improve the reproducibility of the research conducted. Reuse of this protocol must credit the authors and mention its DOI and download link.
