  1. Management And Conservation Of Atlantic Bluefin Tuna (Thunnus Thynnus) And Other Highly Migratory Fish In The Gulf Of Mexico Under IPCC Climate Change Scenarios: A Study UsingRegional Climate And Habitat Models PI: Mitchell A. Roffer, Roffer’s Ocean Fishing Forecasting Service, Inc. Your institution logo here • Question: What are the possible effects of climate change on the spawning habitat and fish population dynamics? • Importance: Highly migratory pelagic species - significant ecosystem value, apex predators, economic value, international management, downscaling (IPCC AR4 and AR5) using HyCOM & ROMS and for ecosystem work. • Approach • Refine and develop habitat model by re-analyzing a 28-year time series of fish (NOAA_NMFS) and environmental data (satellite and in situ) in Gulf of Mexico and nearby. Evaluate spatially and temporally the habitat changes over 100 years. • Other: Leveraging previous 1) NASA – NOAA research with bluefin tuna and other large charismatic megafauna and 2) climate work with Intergovernmental Panel on Climate Change (IPCC AR4).
