We’re thrilled to announce that SESAR “2.0” and our new website are officially live. This release is the biggest update to SESAR since its 2004 founding, with new and improved functionality and UI.

Our new guide provides more information on how to use SESAR and documents our updated vocabularies and metadata schema. 

If you want to get familiar and practice registering samples, please use our sandbox. These samples will not be officially registered and can be used as your personal scratch space.

As part of our revamp, all users are now subscribed to a user listserv. We will be sending periodic emails to our users with system updates and notifications. 

Additionally, we have two webinar sessions to showcase these upgrades:

The Index to Marine and Lacustrine Geological Samples (IMLGS) that has been developed and maintained by NOAA’s NCEI, has been decommissioned and will no longer be accessible on the NCEI web site starting May 5, 2025. In order to ensure continued access and updates to the IMLGS, SESAR and NCEI have agreed that SESAR will take over stewardship of this resource. SESAR staff is working with NCEI and the marine and lacustrine repository community to ensure persistence of this valuable resource. 

SESAR is planning a phased approach to continuing the services of the IMLGS: 

Phase Ia (completed December 1, 2025): Provide access to the current content of the IMLGS. SESAR will create a user interface for searching the current IMLGS and displaying search results. The priority is to make the contents of the IMLGS accessible again as quickly as possible and minimize downtime after the May 5 shutdown of NCEI-based Interactive Map Tool.

Phase Ib (completed February 10, 2026): SESAR has assumed management of the IMLGS Curators Listserv, previously hosted by NCEI. This listserv is an unmoderated forum for discussion and announcements related to the Curators group and Index to Marine and Lacustrine Geological Samples (IMLGS) database. To join the listserv, request to join here (log in to a Google email account first, or email info@geosamples.org to be manually added to the list): https://groups.google.com/a/geosamples.org/g/imlgs

Phase II (in progress, requires additional funding): Fully integrate the IMLGS services with SESAR. SESAR is starting to work with NCEI and contributing sample repositories to understand their needs and desires for a streamlined data ingest process and user needs for search. Based on these needs and desires, we will generate an implementation plan and try to identify sources of funding to perform the necessary technical developments.

Please note that much of the IMLGS data remains accessible also via GeoMapApp here.

We are grateful for the many notes of support we have received from the community reiterating the importance of the IMLGS resource and expressing gratitude to SESAR for helping to steward this resource in the future. We thank the community for your continued support and patience with this transition. 

If you have questions or comments, please reach out to us at info@geosamples.org.
