CAS- Climate: Assessing the potential of artificial upwelling to mitigate coral bleaching during heat waves

CAS-气候:评估人工上升流在热浪期间减轻珊瑚白化的潜力

基本信息

项目摘要

Global warming is considered to be the most severe threat to coral reefs by causing heat stress events that lead to coral mass bleaching and reef degradation. This situation motivates the development of interventions that mitigate coral bleaching, such as artificial upwelling (AU). AU uplifts cool deep water to the surface. The overarching objective of this project is to provide improved understanding of how AU could be used for surface water cooling by identifying AU scenarios (depth, intensity) that mitigate coral bleaching effectively, while imposing minimal risk of unwanted side effects. The project will substantially improve understanding of how AU could be used to mitigate coral bleaching during thermal stress, by providing knowledge about the effects of different AU scenarios (different depths and lengths of AU pulses) on coral performance and on reef community structures. Investigating both short- and longer- term effects on coral performance and also assessing effects on community structures go beyond most manipulation studies that investigate organism-specific short-term responses. The resulting data set will be relevant not only for engineers, but also will provide critical knowledge for the coral reef ecology community about the coral’s ability to persist in a warming world.It is hypothesized that favorable results can be achieved by creating daily short-term thermal relief via pulsed AU (e.g., 5h/day) with waters from the mid- to lower photic zone (e.g., ~30-100 m). The immediate and lasting effects of AU on coral physiology during heat stress will be tested by (1) assessing the short-term physiological effects of pulsed AU treatments on heat-stressed corals, (2) assessing the long-term physiological effects of heat stress and pulsed AU experiments on coral recovery and thermal tolerance, and (3) testing the combined effects of pulsed AU experiments, variable temperature, and covarying environmental parameters on corals and coral reef communities. The project location at the Bermuda Institute of Ocean Sciences, Inc. (BIOS) is ideal due to its proximity to coral reefs and available research facilities that provide a highly suitable framework for near-natural manipulation studies, including the Bermuda Marine Mesocosm Facility supported by an NSF Facility grant. Students will be involved via existing BIOS-hosted intern programs, including an NSF-funded REU program. Undergraduate and graduate students will learn about the project in BIOS-run university courses. Public outreach will be attained in particular through the development of a new solitaire-like digital game called “EcoChains: Coral Futures”, where players will respond strategically to ocean warming, ocean acidification, sedimentation, outbreaks of crown-of-thorns starfish, and more in coral reefs. Furthermore, numerous visiting school and university groups will have the opportunity to observe the experimental setup and learn about the project.This project is co-funded by the CBET/ENG Environmental Sustainability program and the Biological Oceanography Program in the Division of Ocean Sciences.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.
全球变暖被认为是对珊瑚礁最严重的威胁,它会引起热应激事件,导致珊瑚群白化和珊瑚礁退化。这种情况促使人们开发出减轻珊瑚白化的干预措施,例如人工上升流(AU)。该项目的首要目标是通过确定有效减轻珊瑚礁形成的 AU 场景(深度、强度),同时将不必要的风险降至最低,从而更好地了解 AU 如何用于地表水漂白剂冷却。影响。该项目将通过提供有关不同 AU 情景(不同深度和长度的 AU 脉冲)对珊瑚性能和珊瑚礁群落结构的影响的知识,大幅提高对 AU 如何用于减轻热应激期间珊瑚白化的理解。 - 对珊瑚表现的长期影响以及对群落结构的影响评估超出了大多数调查特定生物体短期反应的操纵研究的范围。由此产生的数据集不仅与工程师相关,而且还将为工程师提供关键知识。珊瑚礁生态社区关于珊瑚在变暖的世界中持续存在的能力。人们追求的是,​​通过脉冲AU(例如,每天5小时)对中至低光区(例如,〜 30-100 m)。将通过以下方式测试热应激期间 AU 对珊瑚生理学的直接和持久影响:(1)评估脉冲 AU 处理对热应激珊瑚的短期生理影响, (2) 评估热应激和脉冲 AU 实验对珊瑚恢复和耐热性的长期生理影响,以及 (3) 测试脉冲 AU 实验、可变温度和覆盖环境参数对珊瑚和珊瑚礁群落的综合影响百慕大海洋科学研究所 (BIOS) 的项目位置非常理想,因为它靠近珊瑚礁,并且现有的研究设施为近自然操纵研究提供了非常合适的框架,包括百慕大海洋中宇宙设施学生将通过 NSF 资助的现有实习项目参与其中,其中本科生和研究生将在 BIOS 运营的大学课程中了解该项目。通过开发一款名为“EcoChains:珊瑚未来”的新型纸牌游戏,玩家将对海洋变暖、海洋酸化、沉积物、棘冠爆发做出战略性反应此外,众多来访的学校和大学团体将有机会观察实验装置并了解该项目。该项目由 CBET/ENG 环境可持续发展计划和生物海洋学计划共​​同资助。该奖项反映了 NSF 的法定使命,并通过使用基金会的智力价值和更广泛的影响审查标准进行评估,被认为值得支持。
