New modelling tools for addressing computationally challenging climate science problems involving the ocean carbon cycle

需要新的计算效率高的建模技术，使一些关键问题有关的海洋碳循环变得易于处理。海洋碳循环模型的计算量很大：深海需要几千年才能与表面通量达到平衡：许多关键的动力学过程必须由海洋模式来解决，以代表相关的海洋环流，这些动力学过程都是小尺度的（在南大洋约10公里），更现实的地球化学模型包括对低热带海洋生态系统的详细描述，这可能使模型的计算成本增加一倍甚至三倍。学生将探索生成计算有效的海洋碳循环模型的方法。

New computationally-efficient modelling techniques are needed to enable some of the critical questions related to the ocean carbon cycle to become tractable. Ocean carbon cycle modelling is computationally intensive: it takes several thousand years for the deep-ocean to come into equilibrium with surface fluxes: many of the critical dynamical processes that must be resolved by ocean models to represent the relevant ocean circulation are small scale (of the order 10km in the Southern Ocean), and the more realistic biogeochemical models include a detailed description of lower tropic level marine ecosystems that can double or even triple the model's computational cost. The student will explore approaches to generating comptuationally efficient ocean carbon cycle models.
