The proposed research program will continue the development of the unique and vibrant program in coastal environmental engineering with a focus on oil pollution control at Memorial University. Through the integration of microbiology and environmental engineering, a series of bio-products have been generated and integrated with remediation technologies for oil mitigation in harsh marine and coastal environments in the past five years. The developed bio-products and technologies have been demonstrated through multi-scale tests as effective oil spill response options. They are able to contain, remove, and remediate the oil right after a spill and prior to its further transport into sensitive ecosystems and long-term weathering. The Chair's proposed Term 2 research program will continue to explore marine oil pollution towards the investigation of oil mitigation after the application of oil spill response operations. It will help to answer critical questions such as (i) how the microbes would further help to treat decanted water, which is the waste stream generated after mechanical marine oil spill response operations (e.g., skimming) and a technical bottleneck for oil response operations; and (ii) how the natural marine ecosystems, especially the microbes, react with the residue oil after the chemical oil response operations (e.g., application of dispersants). The program will aim to achieve the marine spilled-oil mitigation through entailing the following tasks: (1) generating innovative methodologies and green bio-products (e.g., bio-demulsifers) by microbes for oil removal from decanted water; (2) investigating bio-dispersed oil mitigation in marine ecosystems; and (3) exploring mitigation and impact of bio-dispersed oil in natural marine ecosystems with the existence of co-contaminants such as microplastics. The proposed research will enhance Canada's competitiveness, and create international impacts in the research field by contributing to the knowledge of coastal environmental engineering and generating promising products and methodologies in support of sustainable development and environmental protection along the coastline of the Arctic and Northern Atlantic oceans.

拟议的研究计划将继续开发沿海环境工程中独特而充满活力的计划，重点是纪念大学的石油污染控制。通过微生物学和环境工程的整合，在过去五年中，已经生成了一系列生物产品，并与用于苛刻的海洋和沿海环境中的石油缓解措施一起生成并集成。通过多尺度测试作为有效的漏油响应选择，已经证明了开发的生物产品和技术。他们能够在溢出后立即包含，去除和补救油，然后再将其进一步运输到敏感的生态系统和长期风化中。主席拟议的2项研究计划将继续探索海上石油污染，以调查采用溢油响应操作后对石油缓解措施的调查。这将有助于回答关键问题，例如（i）微生物将如何进一步帮助处理倒水，这是在机械船舶溢油响应操作（例如掠夺）和用于油反应操作的技术瓶颈后产生的废水； （ii）天然海洋生态系统，尤其是微生物在化学油反应操作后如何与残留油反应（例如，分散剂的应用）。该计划的目的是通过完成以下任务来实现海洋溢出的缓解措施：（1）通过微生物通过微生物来产生创新的方法和绿色生物产品（例如，生物乳化剂）从倒水中去除油； （2）调查海洋生态系统中的生物分散石油缓解； （3）探索生物分散石油在天然海洋生态系统中的缓解和影响，并存在像微塑料等共核代表的存在。拟议的研究将增强加拿大的竞争力，并通过有助于沿海环境工程的知识，并生产有前途的产品和方法来支持北极和北大西洋沿海地区的可持续发展和环境保护，从而在研究领域产生国际影响。
