项目摘要
This project will develop a quantitative understanding of the factors controlling carbon cycling in seagrass meadows that will improve our ability to quantify their potential as blue (ocean) carbon sinks and predict their future response to climate change, including sea level rise, ocean warming and ocean acidification. The research will advance a new generation of bio-optical-geochemical models and tools (ECHOES) that have the potential to be transform our ability to measure and predict carbon dynamics in shallow water systems. The award will also be used to train the next generation of young scientists by supporting the research of an early career scientist, two Ph.D. students, at least 2 undergraduate students, and at least two interns from the Ocean Lakes High School (Va. Beach) Math & Science Academy, under the combined supervision of the PIs. All students will participate in experimental design, implementation and data analysis and will present the findings of their research at major international scientific meetings each year as well as publishing their results in top-ranked peer reviewed journals. PI Zimmerman maintains an ongoing outreach collaboration with the Virginia Aquarium & Marine Science Center to facilitate the development of educational interpretation and programming from this project that will be specifically targeted to the 700,000 Aquarium visitors annually. The physical setting of the Aquarium will be used as a forum to engage the visitors in dialogue about the broader issue of climate change with Aquarium staff and volunteers. Zimmerman is collaborating with the Virginia Aquarium to help design and implement additional educational programs, resources, and exhibits including the development a new Chesapeake Bay tank that will house living seagrasses. The results from this project will be incorporated into Virginia Aquarium's year-long Mentoring Young Scientists program and as standards-based educational materials for use at the Aquarium in programs for schools, scouts and general audiences. At various times throughout project, the PIs and students will participate in the Virginia Aquarium's Speaking of Science lecture series, which are free to general public to help connect our research with the local community.The study will utilize cutting-edge methods for evaluating oxygen and carbon exchange (Eulerian and eddy covariance techniques) combined with biomass, sedimentary, and water column measurements to develop and test numerical models that can be scaled up to quantify the dynamics of carbon cycling and sequestration in seagrass meadows in temperate and tropical environments of the West Atlantic continental margin that encompass both siliciclastic and carbonate sediments. The comparative analysis across latitudinal and geochemical gradients will address the relative contributions of different species and geochemical processes to better constrain the role of seagrass carbon sequestration to global biogeochemical cycles. Specifically the research will quantify: (i) the relationship between C stocks and standing biomass for different species with different life histories and structural complexity, (ii) the influence of above- and below-ground metabolism on carbon exchange, and (iii) the influence of sediment type (siliciclastic vs. carbonate) on Blue Carbon storage. Seagrass biomass, growth rates, carbon content and isotope composition (above- and below-ground), organic carbon deposition and export will be measured. Sedimentation rates and isotopic composition of PIC, POC, and iron sulfide precipitates, as well as porewater concentrations of dissolved sulfide, CO2, alkalinity and salinity will be determined in order to develop a bio-optical-geochemical model that will predict the impact of seagrass metabolism on sediment geochemical processes that control carbon cycling in shallow waters. Model predictions will be validated against direct measurements of DIC and O2 exchange in seagrass meadows, enabling the investigators to scale-up the density-dependent processes to predict the impacts of seagrass distribution and density on carbon cycling and sequestration across the submarine landscape.
该项目将定量了解控制海草草甸碳循环的因素,这将提高我们量化其作为蓝色(海洋)碳汇潜力的能力,并预测其未来对气候变化的反应,包括海平面上升、海洋变暖和海洋酸化。该研究将推进新一代生物光学地球化学模型和工具(ECHOES),它们有可能改变我们测量和预测浅水系统碳动态的能力。该奖项还将用于通过支持一名早期职业科学家、两名博士生的研究来培训下一代年轻科学家。学生、至少 2 名本科生以及至少 2 名来自 Ocean Lakes 高中(弗吉尼亚海滩)数学与科学学院的实习生,并由 PI 共同监督。所有学生都将参与实验设计、实施和数据分析,并将在每年的主要国际科学会议上展示他们的研究成果,并在顶级同行评审期刊上发表他们的研究成果。 PI Zimmerman 与弗吉尼亚水族馆和海洋科学中心保持着持续的外展合作,以促进该项目的教育解释和规划的开发,该项目将专门针对每年 700,000 名水族馆游客。水族馆的物理环境将被用作一个论坛,让游客与水族馆工作人员和志愿者就更广泛的气候变化问题进行对话。齐默尔曼正在与弗吉尼亚水族馆合作,帮助设计和实施额外的教育项目、资源和展览,包括开发一个新的切萨皮克湾水箱,该水箱将容纳活海草。该项目的结果将纳入弗吉尼亚水族馆为期一年的青年科学家指导计划,并作为基于标准的教育材料,供水族馆在学校、童子军和普通观众的项目中使用。在整个项目的不同时间,PI 和学生将参加弗吉尼亚水族馆的科学讲座系列,该系列讲座免费向公众开放,以帮助我们的研究与当地社区建立联系。该研究将利用尖端方法来评估氧气和碳交换(欧拉和涡流协方差技术)与生物量、沉积物和水柱测量相结合,开发和测试数值模型,该模型可以扩大规模以量化海草草甸碳循环和封存的动态西大西洋大陆边缘的温带和热带环境,包括硅质碎屑和碳酸盐沉积物。跨纬度和地球化学梯度的比较分析将解决不同物种和地球化学过程的相对贡献,以更好地限制海草固碳对全球生物地球化学循环的作用。具体来说,该研究将量化:(i)具有不同生命史和结构复杂性的不同物种的碳储量与常备生物量之间的关系,(ii)地上和地下代谢对碳交换的影响,以及(iii)沉积物类型(硅质碎屑与碳酸盐)对蓝碳储存的影响。将测量海草生物量、生长率、碳含量和同位素组成(地上和地下)、有机碳沉积和输出。将确定 PIC、POC 和硫化铁沉淀物的沉积速率和同位素组成,以及溶解硫化物、二氧化碳、碱度和盐度的孔隙水浓度,以开发生物光学地球化学模型来预测海草的影响控制浅水区碳循环的沉积物地球化学过程的代谢。模型预测将根据海草草甸中 DIC 和 O2 交换的直接测量进行验证,使研究人员能够扩大密度依赖过程,以预测海草分布和密度对整个海底景观碳循环和封存的影响。
