Dear all, If you conduct sample-based research (e.g., soil, water, rock, biological, experimental), please read on. As part of the NSF-funded iSamples project<https://isamplesorg.github.io/> and the System for Earth and Extraterrestrial Sample Registration (SESAR)<https://www.geosamples.org/> at the Lamont-Doherty Earth Observatory of Columbia University, we are conducting interviews and user interface evaluations during the AGU 2023 Fall Meeting to gather insights into sample discovery, collection, and reuse practices and challenges across the Earth Sciences. Results from the interviews will inform immediate and long-term improvements to the search interfaces, data submission processes, usability, and interoperability of existing community-curated databases and repositories, and will guide development of resources and support for researchers. Interviews are anticipated to last 20-25 minutes and participants will receive compensation for their time. We are interested in gathering data from as many disciplines and career stages as possible, and encourage students and early career researchers to participate. We are also interested in hearing from collections managers, those who have experience with multi-institutional collaborative grants involving sample collection and sharing, and analytical lab leadership. If you have further questions and/or are interested in setting up a time to participate in this study, either in person at AGU 2023 or virtually via Zoom, please email me at nraia@arizona.edu. We look forward to hearing from you.
