*Reminder* Thank you all for your responses to our survey so far, we appreciate your time. This is a reminder for those that may have missed the initial post. If you haven’t had the chance yet, please consider providing a response at the survey link below. The survey will be available through Sunday, March 14, 2021. Thank you! Greetings, We are reaching out to the greater marine mammal research community to better understand photo-ID data archival challenges and how you all manage these challenges. Some challenges include the availability of and access to well-supported archival platforms that provide multi-decadal stability, access to image processing and analysis tools, and cross-collaborative data-sharing functions. Other concerns may be related to public accessibility, proper attribution for catalog curators and funding sources, and the registering of persistent identifiers (e.g., DOIs) for archives. We encourage all marine mammal researchers who manage photo-ID data collections to respond to the survey link below. The survey will only take a few minutes to complete and it is anonymous. The results will be used to inform a presentation submitted to the Society for Marine Mammalogy Biennial Conference in December 2021. Please feel free to forward the survey link to other marine mammal researchers. If applicable, kindly coordinate with your team to avoid duplicative responses. The survey will be available for responses until Sunday, March 14, 2021. Link: https://forms.gle/ND8MKvCkWKGpcS3b7 We appreciate your help and interest. For questions or technical issues related to the survey please contact photoidsurvey@gmail.com.
