If you were not able to catch up with us at AGU, contact us at info@geosamples.org with questions or comments about our resources.
  • IGSN: Toward a Mature and Generic Persistent Identifier for Samples: This presentation discussed the evolution of the IGSN and our efforts to redesign and improve its existing organization and technical architecture. Slides from this talk can be found here.
  • Increasing the Impact of Your Research by Enabling Persistently FAIR Physical Samples: The System for Earth Sample Registration (SESAR): This poster discussed the benefits of using IGSNs and SESAR, and how SESAR has grown beyond individual investigators to include repositories, museums, and many large-scale scientific initiatives. The poster can be viewed here.
  • Building a Global Network of Geochemical Data: This townhall discussed developing geochemical data standards in the Earth Sciences (and the IGSN as an existing standard that has improved discoverability) and opportunities for a global geochemical data network. To learn more, please refer to the presentation here.
• Dr. Kerstin Lehnert and SESAR participated in PIDapalooza 2019, a conference dedicated to persistent identifiers (PIDs). Dr. Lehnert gave a presentation titled “Transitioning an Identifier System to Persistence” where she discussed the recent Sloan-funded effort to develop a mature organizational and technical structure for the IGSN that is scalable and extensible to other domains, ensuring persistence.
• SESAR participated in the annual assembly of members of the International Implementation Organization for the IGSN (IGSN e.V.). The objective of the IGSN e.V. is to implement and promote standard methods for locating, identifying, and citing physical samples with confidence by operating an international IGSN registration service with a distributed infrastructure for use by and benefit to its members. Membership in the IGSN Implementation Organization is open to organizations who wish to run their own IGSN allocating service.

User Spotlight

In this edition we spotlight Nichole Anest and the team at the Lamont-Doherty Core Repository. The Lamont-Doherty Core Repository (LDCR) contains one of the world’s most unique and important collections of scientific samples from the deep sea. Sediment cores from every major ocean and sea are archived at the Core Repository, which contains approximately 72,000 meters of core and associated metadata. Besides their mission to provide long-term curation and archiving of samples and cores, the Core Repository also fulfills sample requests, assists investigators in sample collection activities, and works tirelessly to educate teachers, students, and the public about the important role science and the Core Repository play in building a better understanding of Earth processes.

We caught up with Nichole to learn more about how the Core Repository uses the IGSN and SESAR to manage their samples, and to explore some of their exciting sample collections. Read more below:

Why do you use SESAR? We use SESAR because it makes it possible to track samples through time and publications. I get many students requesting samples that someone used in a paper years to decades ago but the information in the paper about the samples is usually limited or non-existent. So, we have to go back through our paper sampling histories to locate the PI, what core(s) and at what intervals they sampled, and try to piece together what samples' data were used for the published work. The use of IGSNs makes these sort of sample requests much easier as well as giving "automatic" acknowledgement to the repository where the samples came from.

Sample group highlight: There are about two hundred cores that were taken by the Bureau of Ocean Energy Management (BOEM), part of the US Dept of the Interior, to look for near-shore sand deposits. They wanted to identify where beach sand was transported after major coastal storms (such as Irene and Sandy) and see if it is feasible to use it to replenish the beaches after such storms. Check out the BOEM cores in SESAR which include core photos as well as grain size data.

May 2018. Nearly 7,000 holes drilled across the globe in collaboration with the Continental Scientific Drilling Coordination Office have been registered in SESAR. These holes now have persistent and globally unique identifiers (IGSNs) and can be linked to core samples extracted from the holes. Check them out in the SESAR Catalog by searching Set Name/IGSN -> IGSN begins with "CDR". These holes were registered as part of Open Core Data, an NSF-funded project that is radically improving discoverability, accessibility, citeability, preservation, and integration of data from past, current, and future drilling and coring projects.

Apr 2018. SESAR version 7.1.1 is released, which includes new features, enhancements, and improvements.
  

• New Feature: An option to preview sample locations on a map is now provided when you upload a SESAR batch registration or batch upload template in MySESAR. You can access the map by clicking "View Locations on Map." Locations are only shown if you have entered values for Latitude and Longitude (not UTM). You can see if samples plot in expected locations and, if not, you can adjust coordinates in your batch template and re-upload it, eliminating the need to edit sample metadata at a later time or involve the SESAR curator. We recommend that you double-check your sample locations by viewing your samples on a map each time you upload a batch registration template.

Nov 2017. Undergraduate students in the Computer Sciences Department at the College of Charleston are developing open-source software applications that make it easier to document and register scientific samples in the System for Earth Sample Registration (SESAR) to improve discovery and access to these valuable research resources for future use. The students are working under the direction of Dr. Jim Bowring in the Cyber Infrastructure Research & Development Lab for the Earth Sciences (CIRDLES). Four of the students recently presented their work at the 2017 Geological Society of America Annual Meeting. MARS, Middleware for Assisting with the Registration of Samples, is highlighted below.
 
MARS: Middleware for Assisting with the Registration of Samples
Tia Curry is the latest student from the CIRDLES lab to work on developing MARS, an open-source, cross-platform desktop and web application that streamlines the bulk registration of samples in the SESAR sample registry. The application, which is still in development, allows investigators to register samples using their own preferred sample metadata file, rather than having to rearrange sample metadata to fit into the SESAR batch registration template. Users should also supply a mapping file that maps SESAR metadata fields to fields in their sample metadata files. MARS takes advantage of existing SESAR sample registration web services to validate and register samples. Once IGSNs are assigned, they are automatically inserted back into the user's original sample metadata file, eliminating the need to copy and paste or wait for an email. Check out Curry's recent presentation about MARS here.
 
MARS was originally developed to assist with the registration of thousands of legacy cores archived at the Scripps Institution of Oceanography. For Geological Collections Manager Alex Hangsterfer, the time required to rearrange countless spreadsheets worth of metadata in order to upload those spreadsheets to SESAR was simply not feasible. Although MARS was initially prototyped to facilitate the registration of the Scripps core collection, its highly extensible architecture will allow broad adoption.
 
The idea for MARS originally came about when Hangsterfer shared her challenges with Bowring and others at the Kickoff Meeting of the EarthCube iSamples Research Coordination Network (RCN) in 2015 and from there, a working group was formed to investigate tools to lower the barriers to use of the International Geo Sample Number (IGSN), the globally-unique identifier for physical samples. The IGSN, itself, has been recognized as an important tool for uniquely identifying samples in the lab and in the literature, as well as for linking samples to data, publications, and funding awards. Because resources can vary widely from one organization to another, open-source and extensible development of tools like MARS is immensely important for facilitating widespread adoption and use of the IGSN. Efforts like the iSamples RCN are also pivotal for providing a forum for diverse stakeholders, like computer scientist Bowring and geological collections manager Hangsterfer, to engage with one another. The RCN also provided modest student support to carry out development.
