There are concerns about the declining health of ocean ecosystems today, and similar events in the past can provide information about how our current ecosystems might survive. One such event occurred during the Early Jurassic about 183 million years ago when reefs experienced major extinctions during periods of warm, low-oxygen, acidic oceans. This Early Jurassic event is recorded in great detail in the Moroccan High Atlas Mountains, and research there is establishing (1) when ecosystems disappeared; (2) which organisms survived (and which did not), and (3) what environmental changes led to ecosystem collapse. To share this work with the public, a board game is being designed to educate players about Jurassic reefs, evolution, and extinction in the face of extreme environmental change. This game is integrated into middle school, high school, and college-level educational modules; it can also be enjoyed by the general public and will be made available in multiple languages, thus enhancing science literacy, both locally and internationally.The primary research questions being addressed are: (1) When precisely does ecosystem collapse occur in the Early Jurassic and was it synchronous across ecosystem types (i.e., reefs versus level-bottom communities)? (2) What kill mechanism(s) (e.g., anoxia, acidification) caused biotic collapse and are they linked to large igneous province emplacement? (3) What were the timing and tempo of recovery for marine communities? These issues will be answered through field-based, interdisciplinary research in the Moroccan High Atlas. Quantitative paleoecological and sedimentological surveys are being combined with a suite of geochemical data (e.g., proxies for temperature, volcanism, and water oxygen levels) to understand the causes, timing, and consequences of biotic collapse in the Early Jurassic. This integrated, multi-disciplinary synthesis is informing paleontologists, ecologists, and climate scientists about the conditions that allowed certain ecosystems to survive a major global catastrophe. The educational efficacy of the board game is assessed through beta trials in local schools and universities with self-reported surveys of enjoyment and learning outcomes from both students and teachers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

人们对今天海洋生态系统健康状况的下降感到担忧，过去的类似事件可以提供有关我们目前生态系统如何生存的信息。其中一个这样的事件发生在大约1.83亿年前的侏罗纪早期，当时珊瑚礁在温暖、低氧、酸性海洋期间经历了重大的灭绝。这一早侏罗世事件在摩洛哥阿特拉斯山脉被详细记录下来，那里的研究正在确定（1）生态系统何时消失;（2）哪些生物幸存下来（哪些没有），以及（3）什么环境变化导致生态系统崩溃。为了与公众分享这项工作，正在设计一款棋盘游戏，以教育玩家在极端环境变化下的侏罗纪珊瑚礁，进化和灭绝。这款游戏被整合到初中、高中和大学的教育模块中;它也可以被公众所享受，并将以多种语言提供，从而提高当地和国际的科学素养。正在解决的主要研究问题是：（1）早侏罗世生态系统崩溃发生的确切时间以及它在不同生态系统类型中是否同步（即，珊瑚礁与海底群落）？(2)什么样的杀伤机制（例如，缺氧，酸化）造成的生物崩溃，它们是否与大火成岩省侵位有关？(3)海洋生物恢复的时间和克里思如何？这些问题将通过摩洛哥高地图集的实地跨学科研究来回答。定量古生态学和沉积学调查正与一套地球化学数据相结合（例如，温度、火山活动和水中含氧水平的替代物），以了解早侏罗纪生物崩溃的原因、时间和后果。这种综合的、多学科的综合正在向古生物学家、生态学家和气候科学家提供信息，使他们了解某些生态系统能够在一场重大的全球灾难中幸存下来的条件。该棋盘游戏的教育功效是通过当地学校和大学的测试版测试来评估的，并对学生和教师的享受和学习成果进行自我报告调查。该奖项反映了NSF的法定使命，并通过使用基金会的评估被认为值得支持智力优点和更广泛的影响审查标准。
