项目摘要

Carbon sedimentation (10 Pg C/year) via the ocean biological carbon pump is important to the regulation of atmospheric CO2, yet is poorly observed in space and time due to limitations of current methodology (moorings/ships), and thus is poorly understood and consequently is poorly represented in carbon cycle simulations. Current estimates of the strength of the ocean biological carbon pump are highly uncertain. The one year project will deploy and calibrate low-cost robotic ocean-profiling current-following Carbon Flux Explorers (CFEs) which is a necessary step paving the way high frequency broad scale monitoring and prediction of carbon sedimentation in the ocean. Project scientists will work with the San Francisco Exploratorium to enhance public knowledge of the ocean carbon cycle, ocean robotics. UC Berkeley undergraduate students will be exposed to this research activity in the class-room, as laboratory assistants, and in hands-on experience at sea. The CFEs represent the integration of an ocean profiling float ? similar to those widely deployed in the ocean as part of the ARGO program ? with the UC Berkeley / Lawrence Berkeley National Laboratory - developed Optical Sedimentation Recorder (OSR). The CFEs dive to depth and the OSR uses a camera and three modes of illumination to image particles over time as they accumulate in a sediment trap. Periodically the sample is removed and the imaging resumes. The use of transmitted, transmitted cross-polarized transmitted, and side illumination permits three modes of quantification sample loading as measured sample attenuance, sample cross-polarized photon yield, and sample reflectance. The project specifically aims to relate the three optical metrics of sample load to the amount of particulate organic carbon, particulate inorganic carbon (also known as calcium carbonate), and other biogenic particle phases. Thus, the development will demonstrate the ability of the Carbon Flux Explorer to measure the strength of carbon sedimentation in the ocean. In a one year project. Scientists at University of California, Berkeley and engineers at Lawrence Berkeley National Laboratory and Scripps Institution of Oceanography will build/modify 2 Carbon Flux Explorers to enable the collection of samples for their calibration. These and two other CFEs and a surface tethered OSR will be co-deployed during an oceanographic expedition in California coastal and offshore waters. Collected samples will be analyzed and compared with the optical metrics of sample load, collected at the same time. The project will thus meet its major goal of demonstrating that the CFEs can measure the strength of ocean carbon sedimentation as a function of depth, time, and ocean location, in a way here-to-fore impossible to achieve from ships.
通过海洋生物碳泵进行的碳沉积(10 Pg C/年)对调节大气CO2很重要,但由于目前方法(系泊/船舶)的限制,在空间和时间上观察得很差,因此了解得很少,因此在碳循环模拟中表现得很差。目前对海洋生物碳泵强度的估计高度不确定。这个为期一年的项目将部署和校准低成本的机器人海洋剖面海流跟踪碳通量探测器(CFEs),这是为海洋碳沉积的高频大规模监测和预测铺平道路的必要步骤。项目科学家将与旧金山弗朗西斯科探索馆合作,提高公众对海洋碳循环、海洋机器人的认识。加州大学伯克利分校的本科生将在教室里接触到这项研究活动,作为实验室助理,并在海上实践经验。 CFE代表海洋剖面浮标的集成?类似于那些广泛部署在海洋中的ARGO计划的一部分?与加州大学伯克利分校/劳伦斯伯克利国家实验室开发的光学沉降记录仪(OSR)。CFE下潜至深度,OSR使用相机和三种照明模式,随着时间的推移对颗粒进行成像,因为它们在沉积物陷阱中积累。周期性地移除样品并恢复成像。透射、透射交叉偏振透射和侧面照明的使用允许三种模式的定量样品加载,如测量的样品衰减、样品交叉偏振光子产率和样品反射率。该项目的具体目标是将样品负载的三个光学指标与颗粒有机碳,颗粒无机碳(也称为碳酸钙)和其他生物颗粒相的量联系起来。因此,该项目将展示碳通量探测器测量海洋碳沉积强度的能力。在一年的项目中。加州大学伯克利分校的科学家以及劳伦斯伯克利国家实验室和斯克里普斯海洋学研究所的工程师将建造/改装2个碳通量探测器,以便收集样品进行校准。在加州沿海和近海沃茨的海洋学考察期间,将共同部署这些CFE和另外两个CFE以及一个表面系留OSR。将对采集的样本进行分析,并与同时采集的样本负载的光学指标进行比较。因此,该项目将实现其主要目标,即证明CFEs可以测量海洋碳沉积强度作为深度,时间和海洋位置的函数,而这是迄今为止船舶无法实现的。
