The project is supported under the NSF Science, Engineering and Education for Sustainability Fellows (SEES Fellows) program, with the goal of helping to enable discoveries needed to inform actions that lead to environmental, energy and societal sustainability while creating the necessary workforce to address these challenges. Sustainability science is an emerging field that addresses the challenges of meeting human needs without harm to the environment, and without sacrificing the ability of future generations to meet their needs. A strong scientific workforce requires individuals educated and trained in interdisciplinary research and thinking, especially in the area of sustainability science. With the SEES Fellowship support, this project will enable a promising early career researcher to establish herself in an independent research career related to sustainability. This project focuses on the sustainability of shelfish harvesting in Alaska.In Alaska, paralytic shellfish poisoning caused by the marine alga Alexandrium is a severe and persistent problem that significantly impacts human health and the availability of shellfish resources. This project aims to enhance sustainability of commercial, recreational and subsistence shellfish harvest in Southeast Alaska by addressing the ecology of Alexandrium harmful algal blooms and their sociocultural impacts. Despite the recognized impacts of paralytic shellfish poisoning, little research has been done on the causative organism, Alexandrium, and the sociocultural impacts of toxic Alexandrium blooms in the Southeast Alaska region. This study is a three-pronged effort. First, the project bolsters understanding of the ecological mechanisms that promote Alexandrium blooms by mapping cyst seedbeds (i.e., bloom initiation sites), monitoring cyst emergence, and identifying environmental conditions under which blooms form. This information adds to the body of scientific knowledge about Alexandrium bloom dynamics in coastal, fjord systems, provide early-warning information about toxic bloom development and help focus future paralytic shellfish poisoning testing and harmful algal bloom monitoring efforts in Southeast Alaska. Second, the application of novel in situ sensors will overcome previous benthic emergence monitoring challenges and has the potential to improve harmful algal bloom forecasting capabilities. Third, human dimensions research will generate critical information about how social systems can reduce vulnerability to harmful algal blooms and how local/traditional knowledge can support scientific efforts by establishing strong community partnerships. The SEES Fellow, Dr. Elizabeth Tobin, works with host mentor Dr. Ginny Eckert at the University of Alaska Fairbanks, and with partner mentor Dr. Thomas Leschine at the University of Washington.

该项目得到了NSF科学，工程和可持续发展研究员教育计划（SEES Fellows）计划的支持，目的是帮助实现所需的发现，以告知导致环境，能源和社会可持续性的行动，同时创造必要的劳动力来应对这些挑战。可持续发展科学是一个新兴领域，它解决了满足人类需求而不会损害环境的挑战，也没有牺牲子孙后代满足其需求的能力。强大的科学劳动力要求接受接受跨学科研究和思维的个人，尤其是在可持续发展科学领域。借助SECE奖学金支持，该项目将使有前途的早期职业研究人员能够在与可持续性有关的独立研究职业中建立自己。该项目着重于阿拉斯加的阿拉斯加货架收获的可持续性，由海洋藻类亚历山大（Alexandrium）引起的麻痹贝类中毒是一个严重而持久的问题，对人类健康和贝类资源的可用性产生了重大影响。该项目旨在通过解决亚历山大有害藻华及其社会文化影响的生态，以提高阿拉斯加东南部商业，休闲和生存贝类收获的可持续性。尽管瘫痪贝类中毒的影响有了公认的影响，但对阿拉斯加东南地区有毒亚历山德里姆布鲁姆的病因，亚历山德里姆和社会文化影响的研究很少。 这项研究是一项三管齐下的努力。 首先，该项目通过绘制囊状苗床（即，监测囊肿的出现并识别出开花形成的环境条件）来理解促进亚历山大盛开的生态机制。这些信息增加了有关沿海峡湾系统中亚历山德里姆·布鲁姆动态的科学知识，提供了有关有毒布鲁姆发育的早期训练信息，并有助于将未来的麻痹性贝类中毒测试和有害的阿尔加尔·布卢姆监测在阿拉斯加东南部进行。 其次，新颖的原位传感器的应用将克服以前的底栖出现监测挑战，并有可能提高有害的藻华预测能力。第三，人类维度研究将产生有关社会系统如何减少对有害藻类绽放的脆弱性以及当地/传统知识如何通过建立强大的社区伙伴关系来支持科学努力的关键信息。 这位研究员伊丽莎白·托宾（Elizabeth Tobin）博士与阿拉斯加大学Fairbanks大学的主持人Ginny Eckert博士一起工作，并与华盛顿大学的合伙人导师Thomas Leschine博士合作。
