Peer review declaration

All papers published in this volume of IOP Conference Series: Earth and Environmental Science have been peer reviewed through processes administered by the Editors. Reviews were conducted by expert referees to the professional and scientific standards expected of a proceedings journal published by IOP Publishing. Type of peer review: Single-blind / Double-blind / Triple-blind / Open / Other (please describe) A special, cleaned version of every manuscript was prepared by the conference team member for the peer review procedure with most of identity determining data being removed/censored. Cleaned manuscripts were sent to various potential peer reviewers for initial skimming that eventually would lead to their acceptance or decline for the peer review. In case of acceptance, the deadline was decided and the special form was issued for peer reviewer to fill his commentary on the manuscript. Every paper needed at least two positive reviews and more peer review queries were made in case of disputes over the quality of the work. At no point in the procedure the reviewers or the author knew the identities of any party involved. • Conference submission management system: Microsoft Conference Management Toolkit • Number of submissions received: 37 (out of 109 conference submissions) • Number of submissions sent for review: 23 for IOP Peer Review • Number of submissions accepted: 21 • Acceptance Rate (Number of Submissions Accepted / Number of Submissions Received X 100): 56,76% • Average number of reviews per paper: 2 • Total number of reviewers involved: 43 • Any additional info on review process: • Contact person for queries: Mateusz Karczewski: mateusz.karczewski@agh.edu.pl
