0736045This exploratory project is to prototype the development of a Community Environment for Advanced Oceanic Modeling (CEAOM). An environment is a framework of protocols, software, documentation, resources and experience that facilitates i) the assessment of ocean models and techniques; ii) the interchange of concepts, capabilities and software (parameterizations, numerical algorithms, forcing, etc.); iii) test beds for the exploration of different modeling approaches; iv) estimates of uncertainties by ensembles of ocean models; v) easier access to "best practice" ocean models; vi) maintenance and continued development of ocean models. For these reasons, a Community Environment benefits both ocean model developers and ocean model users, as well as Earth System science as a whole. This project will examine and prototype certain aspects of such a broader environment.Intellectual MeritThe work proposed focuses on developing methods and establishing strategies for collaboration on ocean model development with biogeochemistry. The essential goals are to devise protocols to facilitate model interoperability (e.g. grid formats, forcing and initial condition specification); examine experimental design for comparison of models within the environment; examine the module/subroutine interfaces and protocols for adding bio-geochemical modules; explore the interoperability and inter-comparison of models for bio-geochemical studies; test the method using a proto-biology (simple NP) model in significantly idealized physics configurations; understand the impact of physical parameterizations on the bio-geochemical systems; propose a framework to compare and evaluate models in realistic global scale configuration.The specific inter-comparisons will address significant outstanding questions: What is the source of the differences between the CLIVAR-sponsored global "Common Ocean Reference Experiment" (CORE) ocean climate simulations? What effects do the representation of the physical ocean circulation and processes have on the portrayal of bio-geochemical processes in ocean models? The results will be highly informative and relevant for societally important questions. Moreover, the proposed activities are clearly the correct initial steps for organizing the community for the subsequent development of the graceful, flexible and reliable Community Environment for Advanced Oceanic Modeling, which would meet clear needs for so many critical areas.Broader ImpactsThe proposed work is a preliminary step toward the development of a community-based Ocean Modeling Environment. The need for such an environment has been repeatedly emphasized in high profile nationwide planning documents. In the long-run, this environment is likely to provide the essential ocean modeling tools to address well-documented national needs in such areas as ecosystem-based resource management, public health (e.g. harmful algal blooms), marine transportation, national defense, and regional and global climate and ocean weather forecasts. At the same time, it will speed our understanding of the ocean system by improving the modeling tools available to academic researchers. Additionally, this approach will greatly accelerate the improvement of these tools themselves by facilitating more direct collaboration between developers and exchange of techniques. In short, this project stands a high likelihood of leading ultimately to significant improvements in our ability to model the ocean, while at the same time streamlining the human efforts required to use and utilize ocean models.

0736045这个探索性的项目是开发一个先进的海洋建模社区环境（CEAOM）的原型。环境是协议、软件、文件、资源和经验的框架，有助于㈠评估海洋模式和技术; ㈡交换概念、能力和软件（参数化、数值算法、强迫等）;㈢探索不同建模方法的试验台; ㈣通过海洋模型集合估计不确定性; ㈤更容易获得“最佳做法”海洋模型; ㈥维持和继续发展海洋模型。由于这些原因，社区环境有利于海洋模型开发人员和海洋模型用户，以及整个地球系统科学。该项目将研究和原型这样一个更广泛的环境的某些方面。智力MeritThe拟议的工作重点是开发方法和建立战略，合作开发海洋模型与地球化学。基本目标是设计协议以促进模型的互操作性（例如网格格式、强迫和初始条件规范）;审查环境内模型比较的实验设计;审查增加生物地球化学模块的模块/子程序接口和协议;探索生物地球化学研究模型的互操作性和相互比较;用原始生物学来测试这个方法（简单NP）模型在显著理想化的物理配置;理解物理参数化对生物地球化学系统的影响;提出一个框架，以比较和评估模型在现实的全球尺度配置。具体的相互比较将解决重要的突出问题：CLIVAR赞助的全球“共同海洋参考实验”（CORE）海洋气候模拟之间差异的来源是什么？物理海洋环流和过程的表示对海洋模式中生物地球化学过程的描述有什么影响？结果将是高度翔实和相关的社会重要问题。此外，拟议的活动显然是正确的初始步骤，组织社区的优雅，灵活和可靠的社区环境的先进的海洋建模，这将满足明确的需求，这么多的关键areas.Broader ImpactsThe拟议的工作是一个基于社区的海洋建模环境的发展的初步步骤。这种环境的必要性已在备受瞩目的全国性规划文件中反复强调。从长远来看，这种环境可能提供必要的海洋建模工具，以满足各国在以下领域的需求：基于生态系统的资源管理、公共卫生（例如有害藻华）、海洋运输、国防以及区域和全球气候和海洋天气预报。与此同时，它将通过改进学术研究人员可用的建模工具来加快我们对海洋系统的理解。此外，通过促进开发人员之间更直接的协作和技术交流，这种方法将大大加快这些工具本身的改进。简而言之，该项目很有可能最终导致我们对海洋建模能力的重大改进，同时简化使用和利用海洋模型所需的人类努力。
