Dear colleagues, We enthusiastically invite you to submit an abstract to our Ocean Sciences Meeting 2024 session, “ME004 - Leveraging historical archives to reconstruct ecological processes across temporal and spatial scales”. https://agu.confex.com/agu/OSM24/prelim.cgi/Session/195406 Our session aims to highlight research using historical archives (broadly defined, but some examples are museum collections, isotopes, ancient DNA, oral histories, etc.) to study ecological and oceanographic processes across the full biological spectrum over decadal to millennial scales within the Holocene. Specifically, we invite researchers and studies that are exploring the past to better understand the future of ecosystems worldwide. Studies that include any aspect of marine mammal biology, including but not limited to, marine mammal behavior (broadly defined), their habitats, or their ecological roles, are encouraged to submit an abstract. *We are committed to amplifying diverse voices, practices, and lived experiences to develop a more just, equitable, diverse, and inclusive field*. To achieve this, we hope that you will share this announcement widely within your network. Abstract submissions are due September 13, 2023. Please feel free to reach out with any questions, and thank you for your consideration! Cheers! Jonathan Cybulski, Kerri Smith, Matthew Ramirez, and Kelton McMahon *--Kerri J.
