Global Biogeochemical Flux Models

小行星9314707 这项工作的总体目标概括为联合全球海洋观测系统两个主要目标中的第二个：“发展在全球范围预测海洋生物地球化学过程对人为扰动，特别是与气候变化有关的扰动的反应的能力”（联合全球海洋观测系统国际科学计划，1990年）。这项工作的一个主要重点是确定二氧化碳的海气交换的碳循环过程。 实现这些目标需要海洋地球化学过程模型以及物理过程的三维海洋环流模型（OGCM）。物理模式是基于Brian（1969）发展的原始方程海洋模式。地球化学模型开发工作分为两部分。 其中一个侧重于真光层生态系统模型的发展。 提高我们对控制地表营养物质含量的过程的理解，以及这与碳平衡的关系。 第二项工作的重点是有机物作为溶解的有机物和颗粒从真光层中迁移出来，以及在深海中的再矿化。

9314707 SARMIENTO The overall objective of this work is summed up by the second of the two major JGOFS goals: "to develop a capability to predict on a global scale the response of oceanic biogeochemical processes to anthropogenic perturbations, in particular those related to climate change" (JGOFS International Science Plan, 1990). A major focus of this work is the carbon cycle processes that determine air-sea exchange of CO2. Achieving these goals requires models of biogeochemical processes as well as three-dimensional ocean general circulation models (OGCM's) of physical processes. The physical models are based on the primitive equation ocean model developed by Brian, (1969). The biogeochemical model development effort is divided into two parts. One focusses on the development of ecosystem models of the euphotic zone. To improve our understanding of the processes that control the surface nutrient content and how this is related to the carbon balance. The second effort focusses on transport of organic matter out of the euphotic zone as dissolved organic matter and particles, and remineralization of this in the deep ocean.
