项目摘要
This proposal supports the continuation of the JGOFS core measurement component of the Hawaii Ocean Time series (HOT) program for an additional three years. This HOT JGOFS proposal includes 4 separate, but fully integrated proposals: core measurement component (D. Karl, L. Tupas and D. Hebel, co P.I.s), pigment and phytoplankton component (R. Bidigare, P.I.), inorganic carbon (C.' Winn, P.I.) and zooplankton (M. Landry, P.I.). Since Oct 1988, a comprehensive suite of ocean measurements and results of in situ experiments have been obtained at the oligotrophic Station ALOHA (22'45N, 158'00'W) in the subtropical North Pacific Ocean. The core measurements were selected to provide a data set to validate existing C-N P biogeochemical models and, if necessary, to improve them. Foremost in importance among the various ecosystem processes under investigation are: the flux of carbon at the air sea interface, the rates and control mechanisms of primary production and particle export, and the pathways and intensities of inorganic nutrient (N and P) fluxes. Equally important are the observed time dependent changes in microbial biomass and biodiversity, and the relationships of these observed ecosystem changes to the broader extratropical climate forcing such as El Nino Southern Oscillation (ENSO) and other large scale ocean atmosphere interactions. The emergent data set from the HOT program is unique, robust and rich with previously undocumented phenomena. The HOT program data base is fully accessible with unrestricted use by anyone through the worldwide Internet system (ftp) and, more recently, via the world wide web with only an approximately 6 12 month processing delay. The scientific results of the HOT research program have provided an unprecedented view of biogeochemical cycles in a previously undersampled region of the world ocean. Numerous HOT related publications and reports have already appeared based on the research results obtained by a broad spectrum of HOT program associated and independent scientists. At the same time, this ocean research program has provided an unique educational opportunity for undergraduate and graduate students from Hawaii and around the world, both in terms of at sea field experience and in the classroom working with the computer accessible HOT program environmental data sets. Funding will be used to continue this successful ocean time series core measurement program for the period Aug 1998 to July 2001 and supplement these measurements with an additional mooring.
该提案支持将夏威夷海洋时间序列方案的JGOFS核心测量部分再延长三年。这个HOT JGOFS提案包括4个独立但完全集成的提案:核心测量组件(D。卡尔湖Tupas和D. Hebel,co P.I.s)、色素和浮游植物组分(R. Bidigare,P.I.),无机碳(C. ' Winn,P.I.)和浮游动物(M. Landry,P.I.)。自1988年10月以来,在北太平洋亚热带贫营养海洋ALOHA站(22'45 N,158' 00 'W)进行了一系列海洋测量和现场实验。选择岩心测量值是为了提供一个数据集,以验证现有的碳氮磷地球化学模型,并在必要时,以改善他们。在所调查的各种生态系统过程中,最重要的是:在海气界面的碳通量,初级生产和颗粒输出的速率和控制机制,以及无机营养盐(N和P)通量的途径和强度。同样重要的是观察到的微生物生物量和生物多样性随时间的变化,以及这些观察到的生态系统变化与更广泛的热带外气候强迫,如厄尔尼诺南方涛动(ENSO)和其他大尺度海洋大气相互作用的关系。HOT计划的紧急数据集是独特的,强大的,丰富的,以前没有记录的现象。热程序数据库是完全无限制地使用任何人通过全球互联网系统(FTP),最近,通过万维网只有大约6 - 12个月的处理延迟访问。HOT研究计划的科学成果为以前采样不足的世界海洋区域提供了前所未有的地球化学循环视图。许多与HOT相关的出版物和报告已经出现,这些出版物和报告是基于广泛的HOT项目相关和独立科学家的研究结果。与此同时,这个海洋研究计划为来自夏威夷和世界各地的本科生和研究生提供了一个独特的教育机会,无论是在海上实地经验方面,还是在课堂上使用计算机可访问的HOT程序环境数据集。资金将用于在1998年8月至2001年7月期间继续进行这一成功的海洋时间序列核心测量方案,并以额外的系泊来补充这些测量。
