项目摘要
ABSTRACTOCE-0241752OCE-0241385Scientists from the University of Maine and San Francisco State University propose to do deck-board incubation experiments in high nutrient, low chlorophyll (HNLC) waters of the eastern (Ocean Station PAPA) and the western (Ocean Station KNOT) Subarctic Pacific Ocean to determine how Fe supply affects phytoplankton species composition. Specifically, this team of scientists plans to address the following specific objectives: (1) assess how the relative availability of Fe bound to weaker and stronger classes of ligands differs among different phytoplankton groups (cyanobacteria, diatoms, dinoflagellates, prymnesiophytes) and how these differences influence the evolution of the phytoplankton community after Fe enrichment in HNLC waters; (2) ascertain if new ligands produced in response to Fe enrichment of HNLC waters behave similarly to ambient ligands, or if they have significantly different effect on regulating how an ecosystem evolves over the long term; and (3) determine whether phytoplankton assemblages in HNLC waters having different proximity or history of Fe inputs respond differently to the same suite of Fe ligand blends, or whether conditioning has led to their adaptation of alternate uptake capabilities. In addition, measurements of growth rates, macronutrient utilization rates, fluorescence, cell size determinations, Fe use efficiencies, rates of Fe and carbon uptake and flow cytometry sorting will be done to assess how specific organisms will respond to Fe supplied in different chemical forms.
来自缅因州大学和弗朗西斯科州立大学的科学家们建议在亚北极太平洋东部(海洋站PAPA)和西部(海洋站KNOT)的高营养、低叶绿素(HNLC)沃茨进行甲板培养实验,以确定铁供应如何影响浮游植物物种组成。 具体来说,这个科学家小组计划解决以下具体目标:(1)评估不同浮游植物群体中与较弱和较强配体结合的铁的相对可用性如何不同(蓝细菌、硅藻、腰鞭毛虫、原生植物)以及这些差异如何影响HNLC沃茨水域铁富集后浮游植物群落的进化;(2)确定响应于HNLC沃茨的Fe富集而产生的新配体是否与环境配体的行为相似,或者它们是否对调节生态系统如何长期演化具有显著不同的影响;以及(3)确定具有不同接近度或Fe输入历史的HNLC沃茨中的浮游植物组合是否对同一套Fe配体混合物有不同的响应,或者条件反射是否导致了它们对交替吸收能力的适应。 此外,还将测量生长速率、常量营养素利用率、荧光、细胞大小测定、铁利用效率、铁和碳吸收率以及流式细胞术分选,以评估特定生物体对以不同化学形式提供的铁的反应。
