Save our Marine Annually Resolved Proxy Archives (MARPA)!

Abstract for our poster:

Funding agencies, such as the National Science Foundation (NSF), require detailed Data Management Plans (DMP) for proposals that include plans for archiving data and physical samples yet there is no guidance on what is acceptable for a given community. Several groups are working on improving platforms for sharing data (NOAA Paleoclimatology, Pangaea, EarthCube, and Linked Earth); however, no efforts are being made for curation of physical samples for our community. This is the time for the Sclerochronology community to join this initiative and to work on defining the standards needed for our field in order to curate physical samples, data derived from those physical samples, and metadata from both to promote the expansion of research while giving the original researchers credit and recognition for their work. Marine Annually Resolved Proxy Archives (MARPA) is a grass roots effort created under the EarthCube umbrella ( that is currently working on recommendations for physical samples to include in DMPs by identifying current resources that can be used by researchers.
There are several resources for curating physical samples currently in place that the MARPA working group reviewed. The System for Earth Sample Registration (SESAR; is a NSF-funded cyberinfrastructure that provides a registry for physical samples with their metadata. SESAR offers tools and services for users to manage their physical sample metadata and obtain International Geo Sample Numbers (IGSN; for citation of physical samples. The IGSN was developed by SESAR and has become an internationally recognized standard for sample identification. Several publishers, including AGU journals and Palaeogeography, Palaeoclimatology, Palaeoecology (Elsevier), are now requiring the use of IGSN in their publications. The MARPA working group is developing a web site ( with pertinent information for the community including a tutorial for entering physical sample metadata in SESAR, sample DMPs for proposals and grant reports, and a white paper reviewing and making recommendations for physical sample  and geochemical data curation. Additionally, we are seeking feedback on a template for data sharing for the sclerochronology community, likely in Excel format, complete with standardized vocabulary that could be stored locally offline with each researcher before submitting to a permanent repository (NOAA Paleoclimate and/or Pangaea). This effort will help the Sclerochronology community share their data with the wider community for data synthesis projects, such as Oceans2k and Iso2k, while receiving credit for their work.
