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建模工具，以量化亚北极太平洋的渔业生产和二氧化碳吸收能力。利用在温哥华岛周围和亚北极太平洋近海的研究巡航上部署的航海仪器，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，这些实地观测将用于生成基于卫星的模型，量化生态系统生产力及其对各种环境扰动的响应。这些卫星模型的产出将与渔业数据一起用于审查鱼类产量与环境变化之间的联系。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。这项工作将代表大学科学家与加拿大渔业和海洋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和执行目前有关海洋施肥活动的监管机制。

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.
