DGGS Report of Investigation Publications

A Report of Investigation presents new geologic observations, data, and interpretations. Studies published in this series are typically the final outcome of original research and usually include an exhaustive analysis that is unlikely to be superseded by ongoing work of the authors. An RI undergoes peer-review by two or more subject-matter experts; at least one reviewer will not be affiliated with DGGS. Extensive copyediting and formatting are completed after peer review. Interpretations presented in an RI may be augmented with auxiliary files and/or related publications with distinct DOIs.
