The recent Bering Sea Ecosystem Study (BEST) program and its partner the Bering Sea Integrated Ecosystem Research Program (BSIERP) have resulted in a better understanding of the roles of temperature and stratification in regulating the walleye pollock population, but the role of advection remains poorly understood. Therefore, funds are provided to elucidate how the ocean?s response to variable atmospheric forcing affects the distribution of walleye pollock (Theragra chalcogramma) eggs and larvae on the eastern Bering Sea shelf. The proposed approach builds on advances made under the BEST-BSIERP program and will use a combination of new modeling results and recent observations to examine historical dispersal pathways of pollock eggs and larvae and will simulate how these might change in the future under various scenarios.Advection, the transport of material or a property by the movement of a fluid, plays a major role in the life cycle of many fish populations because early life history stages depend on quasi-passive transport from spawning areas to suitable nursery grounds. Drift trajectories of eggs and larvae and the physical and biological conditions they encounter during the first few months after spawning are highly variable and are linked to regional and broad-scale climate conditions. Thus atmospheric and oceanographic variability affects the survival of early life stages and the resulting year class strength of fish populations, such as walleye Pollock, on the eastern Bering shelf. The results of this project will improve our understanding of the interactions of physical and biological processes on walleye Pollock and, consequently, lead to better management of this important fishery.

最近的白令海洋生态系统研究（BEST）计划及其合作伙伴The Bering Sea Integrated生态系统研究计划（BSIERP）使人们对温度和分层在调节Walleye Pollock人群中的作用有了更好的了解，但对手的作用仍然很众所周知。因此，提供了资金来阐明海洋对可变大气强迫的反应如何影响海角pollock（theragra chalcogramma）卵和幼虫在东部白令海架上的分布。所提出的方法是基于在Best-BSIERP计划下取得的进步，并将结合新的建模结果和最新观察结果来检查Pollock卵和幼虫的历史分散途径，并将模拟这些方法在各种情况下可能如何在未来发生变化。在各种情况下，材料的运输，依赖于生活的生命，因为材料的运输或生命的运输，因为生活的生命依赖于生命的范围，因为生命的生命依赖于生活循环，因为生命的范围依赖于生活循环，因为这一范围的生命阶段依赖于生命的范围。在合适的托儿所产卵区。卵和幼虫的漂移轨迹以及产卵后的头几个月遇到的物理和生物条件高度可变，并且与区域和广泛的气候条件有关。因此，大气和海洋学的变异性会影响早期生命阶段的生存以及在东部白令架上的鱼类种群（例如Walleye Pollock）的年度阶段的生存。 该项目的结果将提高我们对物理和生物过程对角膜白斑波洛克的相互作用的理解，从而可以更好地管理这一重要渔业。
