Supplement

A data supplement consists of primary data related to a publication. The material is provided as extra file(s). Supplementary data can be archived in the repository of the publisher/journal or in Pangaea. The benefits for a storage in Pangaea are
 * Open Access,
 * own identity with DOI,
 * distribution on the Internet via web services through portals, search engines and library catalogs with an increase of the publications impact,
 * machine readability and thus the option to easily compile data from various publications in one new product.

Mondatory for the definition of a supplement in Pangaea is the complete import of all related primary data and its proofread and acceptance by the author(s). Steps for publishing a supplement are:
 * 1) Import all data; each data set has to be related to the reference.
 * 2) If the supplement consists of several datasets, define a parent by selecting all sets and press . Add title and export filename.
 * 3) Inform the author about data availability by sending the DOI as link and ask for proof-read.
 * 4) Make corrections until the authors final OK.
 * 5) If the supplement consists of one dataset, set its status to supplementary data.
 * 6) If the supplement consists of several datasets, set the status of the parent to supplementary data. The authors of childs and parent are automatically listed as given in the reference.
 * 7) Check the valid appearance of the supplement on the Internet.

If the child>parent grouping is used, the reference related to the data sets will disappear in all childs and only apprear in the parent as supplement to:.

Why should supplements not be archived in the repository of the publisher:
 * Publisher, journal, editors and reviewers do not care about the format of the data
 * Supplements of articles in commercial journals are not in Open Access
 * Data did not underwet a technical review or consistency check
 * Data are not machine readable -> no added value

Examples

 * One data set as supplement: which appears as a link on the papers splash page in ScienceDirect, see
 * Several data sets grouped to a parent set as supplement to a chapter in a book

Supplementary data

offers the opportunity to archive data from earth system research in the public data library PANGAEA (http://www.pangaea.de). Archiving assures a reliable identification and access through a unique supplement DOI. Provision in standard formats makes data machine-readable which allows compilation of results from various source. The supplement is part of the peer-review process and the findings as presented in the paper can be verified by the reviewer and reader.

It its recommended to submit supplementary data to Pangaea parallel to the paper submission; password protection until publication is assured. From the Pangaea-editor the author(s) will receive a DOI to be included in the publication as data reference. After publication, the paper will also show a link to its supplement on the splash page.

Due to the variety of data from the earth system, there are no specific format constraints. When submitting data, the authors may keep some rules in mind as listed at http://wiki.pangaea.de/wiki/Data_submission. Data should be submitted to the chief editor of Pangaea at .
