Quantifying climate-dependent and anthropogenic impacts on ecosystem services in the Subarctic Pacific Ocean; State-of-the-art observational tools to inform policy and management

拟议的研究项目旨在产生新一代观测和模拟工具，以量化次北冰洋的渔业产量和二氧化碳吸收能力。利用部署在温哥华岛周围和近海次北冰洋研究游轮上的海上仪器，我们将描述一系列与海洋环境条件和生物生产力有关的变量。然后，这些实地观测将被用来生成基于卫星的模型，以量化生态系统生产力及其对各种环境扰动的反应。这些卫星模型的输出将与渔业数据结合使用，以审查鱼类产量和环境变异性之间的联系。特别是，我们试图了解气候变化和人为干扰对生态系统动态、二氧化碳吸收能力和鱼类生物量的潜在影响。这项工作将是大学科学家与加拿大渔业和海洋组织之间的战略伙伴关系，该项目的科学成果将大大提高渔业种群评估的准确性，从而加强基于生态系统的管理，并加强目前有关海洋肥化活动的现有监管机制。

The proposed research project aims to generate a new generation of observational and modeling tools to quantify fisheries production and CO2 uptake capacity in the Subarctic Pacific Ocean. Using sea-going instrumentation deployed on research cruises around Vancouver Island and into the off-shore Subarctic Pacific, we will characterize a suite of variables relating to marine environmental conditions and biological productivity. These field-based observations will then be used to generate satellite-based models quantifying ecosystem productivity and its response to various environmental perturbations. Output from these satellite models will be used, in conjunction with fisheries data, to examine linkages between fish yields and environmental variability. In particular, we seek to understand the potential impacts of climate change and human induced disturbances on ecosystem dynamics, CO2 uptake capacity and fish biomass. The work will represent a strategic partnership between university based scientists and Fisheries and Oceans Canada, and the scientific results of this project will significantly increase the accuracy of fisheries stock assessments, leading to enhanced ecosystem-based management and enforcement of currently existing regulatory mechanisms concerning ocean fertilization activities.
