Guidelines for attribution of IsoMAP data products in published work (including but not limited to papers, books, and websites):

  1. Any IsoMAP job used in published work should also be ‘published’ within the IsoMAP system, making it discoverable and usable by other IsoMAP users. You can publish your jobs at any point using the links in the “My Jobs” page.

  2. The IsoMAP job key provides a unique ID for every analysis conducted within the system, and should be used to identify specific data products used in your work. For work using only one or a very small number of products, the appropriate citation format (where XXXX is the job key) is:

    Product creator’s name (year created) IsoMAP job XXXX, Isoscapes Modeling, Analysis and Prediction (version 1.0). The IsoMAP Project.

  3. In cases where you have used a large number of data products, please use the generic IsoMAP citation below and include a list of job keys within or accompanying your publication.

    Bowen G. J., West J.B., Miller C. C., Zhao L. and Zhang T. (current year) IsoMAP: Isoscapes Modeling, Analysis and Prediction (version 1.0). The IsoMAP Project.

  4. In order to ensure proper attribution of the data underlying your analysis, we ask that you also include citations to the primary data sources used in your project. In addition, we encourage you to contact the primary data sources with questions regarding their programs and/or to develop collaborative efforts where appropriate. We intend to develop a process for auto-generating specific data source citations associated with each IsoMAP job, but in the mean time we ask that you refer to the general guidelines below:

    1. For any precipitation isotope model or map jobs, cite:

      IAEA/WMO (2011). Global Network of Isotopes in Precipitation. The GNIP Database. Accessible at:
    2. In addition, for precipitation isotope jobs using data from the USA during the period 1989 – 1995, please also cite:

      Welker, J.M., 2000. Isotopic (d18O) characteristics of weekly precipitation collected across the USA: An initial analysis with application to water source studies. Hydrological Processes, 14: 1449-1464.
    3. For any job using CRU (TS2.1) climate data, cite:

      Mitchell T. D. and Jones P. D. (2005) An improved method of constructing a database of monthly climate observations and associated high resolution grids. International Journal of Climatology, 25, 693-712.
    4. For any job using PRISM climate data, cite:

      PRISM Climate Group (2010) Gridded climate data for the contiguous USA.
    5. For any job using ETOPO elevation data, cite:

      U. S. National Geophysical Data Center (1998), ETOPO-5 five minute gridded world elevation, NGDC, Boulder, Colorado, USA.
  5. IsoMAP data products are the intellectual property of their creators, who retain copyright to these products. By publishing their data products within the IsoMAP system, the creator grants any IsoMAP user the non-exclusive right to download, reproduce, or reuse the product, in part or in whole, in original or modified form, for non-commercial purposes. In so using data products obtained from IsoMAP, the user agrees to abide by the above guidelines on attribution and citation of these products and to refrain from re-distributing the data products.
