Registering Your Samples


MARPA advises that samples be registered with an International Geo-Sample Number (IGSN). IGSN’s can be obtained through the System for Earth Sample Registration (SESAR). The SESAR website allows PI’s to produce custom sample data forms based on the type of sample (e.g., core, grab, slab, etc.) and the volume of metadata obtained for that sample.

For assistance in completing the sample registration process, please see SESAR’s help page and consult MARPA’s video tutorials. Detailed PDF walk-throughs of the registration process can be accessed from SESAR’s site and below.

MARPA Article Published in Eos

The MARPA project team has just published an article detailing the project in the American Geophysical Union’s Eos! The MARPA team hopes to reach the broader paleo-community and start a movement towards consistent standardized methods of metadata reporting and physical sample archiving. Read the full article on the Eos site here.

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 (earthcube.org) 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; http://www.geosamples.org) 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; http://www.igsn.org) 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 (marpasite.wordpress.com) 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.

Workshop on Paleoclimate Data Standards

MARPA will be presenting and participating in the Workshop on Paleoclimate Data Standards at the NOAA World Data Center for Paleoclimatology in Boulder, CO on June 22-23, 2016. Kristine DeLong will be attending the workshop in person and presenting MARPA update to the other attendees.  If you have any concerns and issues you like for her to present or discuss at the workshop, please email her at kdelong@lsu.edu.

The details on this workshop are as follows: The LinkedEarth project was recently funded by the EarthCube program of the US National Science Foundation to (1) enable the curation of a publicly-accessible database by paleoclimate experts and (2) foster the development of paleoclimate community standards. Through multiple discussions with the community, the LinkedEarth team has developed a preliminary data standard (Linked Paleo Data, or LiPD), which is being used by the PAGES2k consortium, and is being considered for adoption by the wider PAGES organization. This standard is the cornerstone of all the code being written as part of LinkedEarth to store, curate, visualize and analyze paleoclimate data. It is now time for this standard to be discussed and extended via face-to-face discussions. Because of its crucial role in paleoclimate data stewardship, the National Center for Environmental Information’s World Data Center for Paleoclimatology is an essential partner for US and international efforts at paleoclimate data standardization. We are thus convening the first workshop on paleoclimate data standards, June 22-23 2016, under the auspices of the WDS/NCEI paleoclimatology division (aka “NCDC paleo”).

MARPA at the 2016 International Sclerochronolgy Conference

MARPA team members Kristine DeLong, Hali Kilbourne, and Branwen Williams will be at 4th International Sclerochronology Conference in Portland Maine to present a poster on the MARPA initiative and discuss MARPA with researchers and anyone interested in the project. Please stop by our poster and we’ll be happy to answer any questions, comments, concerns, and accept valuable feedback on the initiative!
