Joint Spatiotemporal Modeling of Zooplankton and Whale Abundance in a Dynamic Marine Environment

Joint Spatiotemporal Modeling of Zooplankton and Whale Abundance in a Dynamic Marine Environment Bokgyeong Kang1,2, Erin Schliep3, Alan Gelfand1, Chris Clark4, Christy Hudak5, Stormy Mayo5, Ryan Schosberg5, Tina Yack1, Rob Schick1,6 1 2 3 4 5 6 Introduction & Motivation 1. Want to understand NARW foraging ecology 2. Build statistical models for data fusion 3. Amazing amounts of disparate data •Zooplankton distribution and abundance •NARW distribution and abundance •NARW acoustic behavior Center for Coastal Studies, Taken under Permit #25740-01 Bay-Wide Understanding of Prey 2011 See Castillo-Mateo et al., 2023 for model details Data Fusion for NARW Abundance 2011 See Schliep et al., 2024 for model details Model Structure Important Results 2011 What If We Had More Zooplankton? Next Steps •Robust framework for better predictions of distribution and abundance in CCB •More ecological understanding •Conservation implications •Currently extending this to remaining years in CCB •As good as data are, more would be better, especially in terms of spatial coverage for zooplankton (see paper for simulation details) Scan For More Info Center for Coastal Studies, Taken under Permit #25740-01 [email protected] Simulation Data Fusion •Using different data sources that inform on a common process
