As a collaborative effort, the University of Washington, The Nature Conservancy, Benioff Ocean Initiative, and Global Fishing Watch are working on a global analysis of the intersection between large whales and marine shipping traffic to identify hotspots of ship strike risk using global data coverage of vessel and whale occurrence. To supplement the publicly available datasets, we invite researchers and data owners to contribute whale occurrence data. We are specifically looking for any occurrence (e.g., survey, citizen science, tagging) data that is not currently deposited in GBIF/OBIS/OBIS-SeaMapper/Movebank on the following species: Antarctic Minke Whale, Blue Whale, Bowhead Whale, Bryde’s Whale, Common Minke Whale, Fin Whale, Gray Whale, Humpback Whale, North Atlantic Right Whale, Sei Whale, Southern Right Whale, Sperm Whale. If you are interested, please fill out the attached form <https://forms.gle/x76Z84fSPsxMWUwH7> outlining any metadata you have available by Friday June 11th, 2021. Please note that filling out this form does not obligate you to participate in this effort, nor does it guarantee your data will ultimately be included in the analysis, however it is the first step needed to identify gaps in publicly available datasets. Any data accepted for this effort would be used strictly for the purposes outlined and would not be shared externally. All data contributors would receive proper attribution and credit. If you have any questions, please contact Callie Steffen ( calliesteffen@ucsb.edu) Thank you for your support. *Metadata form* https://forms.gle/x76Z84fSPsxMWUwH7
