July 2020. SESAR version 7.4.1 is released
 
On July 27th, we released a new version of SESAR. The release includes new features, enhancements and improvements.
 
New features include adding JSON-LD to our sample profile pages and a new REST API. General enhancements and improvements include updates to our map search and minor bug fixes in our image upload tool and web services.
 
You can read the full list of new features and enhancements on the SESAR Release Notes page.
 
If you have any questions or comments, please contact info@geosamples.org.



SESAR Curator Sarah Ramdeen and Scripps Institution of Oceanography’s Geological Collections Manager Alex Hangsterfer were awarded an ESIP FUNding Friday mini-grant at this year’s ESIP Summer Meeting.  The funds from the grant will be used to support MARS (Middleware for Assisting with the Registration of Samples), a software developed by Dr. Jim Bowring and his group of undergraduate students at the College of Charleston.

 
MARS is an open-source web application that streamlines the registration of samples in SESAR to obtain IGSNs, i.e. globally unique identifiers, for the samples and make them Findable, Accessible, Interoperable, and Reusable (“FAIR”).  The application allows investigators or sample curators to submit sample metadata to SESAR  using their own sample metadata files, rather than having to transfer sample metadata to the SESAR batch registration template.  MARS currently supports mapping of NOAA’s Index to Marine and Lacustrine Geological Samples (IMLGS) metadata to the SESAR schema. Version 1 of MARS will be released in the coming months.
  
The MARS team is working to expand the functionality of the tool to allow any user to create a map between their preferred sample metadata format and SESAR’s to broaden the utility of the tool beyond the marine and lacustrine sample community.  The funding from ESIP will be used to support Dr. Bowring’s students as they continue this effort.  At the ESIP Summer Meeting several sample repositories already expressed interest in adopting the tool.

  • The SESAR team attended the AGU Fall Meeting held in Washington D.C from December 10-14, 2018. See more information below about our presentations at AGU, which included presentations about the IGSN and SESAR and participation in a town hall regarding geochemical data standards. 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

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.

April 2018

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.

January 2018

Jan 2018. SESAR version 7.1.0 is released, which includes many new features and improvements. Some highlights:
  

  • Users may now set release dates when registering samples. Release dates determine when sample metadata is publicly accessible and searchable. If no release dates are specified, sample metadata will be publicly accessible immediately (recommended).
  • Users may now update release dates for sample metadata by editing individual sample profiles in MySESAR, using the MySESAR batch update functionality, or using the update web service.
  • A new batch registration template can now be downloaded from MySESAR. This new template allows users to specify different release dates for each sample in the template, rather than setting a single release date for all samples in the template. If no release dates are specified, sample metadata will be publicly accessible immediately (recommended).
  • An email notification will now be sent to sample owners one month before their sample metadata release dates. This email will notify users of the upcoming release dates and recommend steps for editing release dates if desired.
  • Formatting for dates (e.g., collection date) in batch registration templates has been relaxed. Acceptable date formats now include YYYY-MM-DD and MM/DD/YYYY. Date cells no longer have to be formatted as text.
