项目摘要
Researchers from Scripps Institute of Oceanography, the University of Hawaii, and Skidaway Institute of Oceanography plan to test the hypothesis that iron-light co-limitation at the deep chlorophyll maxima (DCM) is a widespread feature of oceanic stratified euphotic zones, and an important control on phytoplankton community composition and size structure. Three different types of DCM will be investigated: mesotrophic, relatively shallow maxima, deeper, chlorophyll per cell based DCM characteristic of oligotrophic gyres, and the Prochlorococcus maximum found just below the oxic/suboxic boundary in the Eastern Tropical North Pacific. To attain their goals, the scientists will carry out the following tasks during the cruises: (1) characterize water column parameters including basic hydrography, nutrient distributions, iron concentration and speciation, phytoplankton community structure, and primary productivity and photosynthetic efficiency; (2) conduct co-limitation incubation experiments at the three types of DCMs; and (3) determine picoplankton cell division and grazing rates. As regards broader impacts, the researchers plan to recruit undergraduates from both the University of California-San Diego and from an historically black college or university such as Savannah State University via the Collaborations in Integrating Research and Education Program using Research Experience for Undergraduates supplemental funds. A science teacher from California and one from Georgia will be asked to participate in research cruises using supplemental funds from Research Experiences for Teachers. Both teachers will be expected to produce educational materials based on their field experiences. One graduate student from the University of California-San Diego, one from the University of Hawaii and one from Skidaway Institute of Oceanography will be trained and supported as part of this study.
来自斯克里普斯海洋学研究所、夏威夷和斯基德韦海洋学研究所的研究人员计划验证一个假设,即在深海叶绿素最大值(DCM)处的铁光共同限制是海洋分层透光带的一个普遍特征,也是浮游植物群落组成和大小结构的重要控制因素。三种不同类型的DCM将进行调查:中营养,相对较浅的最大值,更深,叶绿素每细胞的DCM特征的寡营养环流,和Prochlorococcus最大值发现低于东部热带北太平洋的好氧/缺氧边界。为实现这一目标,科学家们将在航行期间开展以下工作:(1)确定水柱参数,包括基本水文、营养盐分布、铁浓度和形态、浮游植物群落结构、初级生产力和光合效率;(2)在三种类型的DCM上进行共限制培养实验;(3)测定微型浮游生物的细胞分裂和摄食率。至于更广泛的影响,研究人员计划从加州大学圣地亚哥分校和历史悠久的黑人学院或大学(如萨凡纳州立大学)招募本科生,通过合作整合研究和教育计划,使用本科生研究经验补充资金。一名来自加州的科学教师和一名来自格鲁吉亚的科学教师将被要求参加研究巡航,使用教师研究经验的补充资金。两位教师都将根据他们的实地经验编写教材。作为这项研究的一部分,将培训和支助一名来自加利福尼亚大学圣地亚哥分校、一名来自夏威夷大学和一名来自斯基达韦海洋学研究所的研究生。
