PIs propose to hold a workshop at the Colorado School of Mines, Golden, CO; February 27-29, 2008. The goals of the workshop will be to: (1) determine the key fundamental research areas in carbonates that require new advancements to develop numerical process models for carbonates; (2) determine the time scales on which the carbonate models will operate, and how models aimed at different time scales will be coupled; (3) map the environments and associated process sets for each time scale, and evaluate the state of knowledge for each of these; (4) decide on the best strategy for converting carbonate research results into numerical models that can contribute to the global CSDMS; (5) decide on the best strategy for making carbonate research results and computational methods available for education; and (6) define the scope and timing of following phases for the carbonate modeling project.Participants will include from 30 to 35 international leaders in carbonate sedimentology, stratigraphy, climate-modeling, ocean-modeling, siliciclastic modeling, and numerical modeling. Topics to be addressed at the workshop can include, 1) What are the grand challenges in fundamental research on carbonate facies and platform evolution that incorporate new understanding of the influences of climate, ocean systems, and biology? 2) What are the main processes at different time-scales that build carbonate platforms? 3) How should we model diagenesis, and how might we use reactive transport modeling to accomplish this? 4) In terms of the carbonate suite of numerical models, what are critical time and process scales for modeling? 5) Should the carbonate CSDMS standard strictly specify things like object-oriented structure? 6) What is the best way to supply a central CSDMS core into which user-supplied process modules can be plugged? 7) Can the CSDMS be flexible enough to incorporate different modeling approaches (e.g. rule-based versus traditional deductive), or must we decide on this at the outset? 8) For the traditional case, is it important to make specific tactical choices early, like requiring a particular discretization technique (e.g. finite element) or mesh style (e.g. deforming-grid)? 9) What kind of program architecture will be best able to take full advantage of foreseeable advances in computer design (e.g. advances in parallel computing)?

PI建议于2008年2月27日至29日在科罗拉多州戈尔登的科罗拉多矿业学院举办一次研讨会。 讲习班的目标是：（1）确定碳酸盐中需要取得新进展以开发碳酸盐数值过程模型的关键基础研究领域;（2）确定碳酸盐模型运作的时间尺度，以及如何将针对不同时间尺度的模型结合起来;（3）映射每个时间尺度的环境和相关联的过程集合，并且评估这些中的每一个的知识状态;（4）决定将碳酸盐岩研究成果转化为有助于全球CSDMS的数值模型的最佳策略;（5）决定使碳酸盐研究成果和计算方法可用于教育的最佳战略;以及（6）确定碳酸盐岩模拟项目后续阶段的范围和时间安排。与会者将包括30至35名碳酸盐岩沉积学领域的国际领导人，地层学、气候模拟、海洋模拟、硅质岩模拟和数值模拟。 研讨会将讨论的主题包括：1）在碳酸盐岩相和台地演化的基础研究中，结合对气候、海洋系统和生物影响的新认识，面临哪些重大挑战？ 2)在不同的时间尺度上，形成碳酸盐岩台地的主要过程是什么？ 3)我们应该如何模拟成岩作用，以及我们如何使用反应迁移模型来实现这一目标？ 4)就碳酸盐岩数值模型套件而言，建模的关键时间和过程尺度是什么？ 5)碳酸盐岩CSDMS标准是否应该严格规定诸如面向对象结构之类的内容？ 6)什么是提供中央CSDMS核心的最佳方式，用户提供的过程模块可以插入其中？ 7)CSDMS是否足够灵活，可以合并不同的建模方法（例如，基于规则的与传统的演绎），或者我们必须在一开始就决定这一点？ 8)对于传统的情况，早期做出特定的战术选择是否重要，比如需要特定的离散化技术（例如有限元）或网格样式（例如变形网格）？9)什么样的程序架构能够最好地充分利用计算机设计中可预见的进步（例如并行计算的进步）？
