中文摘要
该项目是一个协调的尝试,以了解生物和物理动力学的相互作用,通过开发南极冬季冰雪覆盖的演变和生物栖息地的变化之间的机械联系,通过模拟环境的光学特性的贡献。 这项工作将在全球海洋生态系统动力学研究的南大洋实验范围内进行,这是一项由多名研究人员对南极海冰下磷虾冬季生存策略进行的大型研究,雪和海冰的光学特性在整个冬季不断变化,在光谱和空间上都有很大差异。 这些特性是物理环境的一个重要因素,强烈影响着南极磷虾的分布和资源。 入射辐射能的强度及其在雪、冰和水柱环境中的分布,以及调制其分布的相关物理、光学、化学和生物过程通常是已知的,但量化得很差。 雪和冰的光学特性也影响雪藻、冰藻和水柱的生产力,以及捕食者和猎物的可见度。 此外,光学特性作为地球物理海冰参数的代用指标,在卫星观测中发挥着至关重要的作用,使当地观测能够在空间和时间上得到更准确的推断,从而提供否则无法实现的区域覆盖。 所提议的是部署一系列装有仪表的冰信标,并通过定期的船基观测和卫星观测加以加强,沿着理论研究,以建立改进的定量模型,跟踪这一冰雪海洋生态系统的时间和空间演变。具体目标是开发一个热力学海冰/通过现有组件的耦合,以测试我们对系统的理解,确定其敏感性,并提供一个整合南大洋Globec观测的组织机制。***
英文摘要
This project is a contribution to a coordinated attempt to understand the interactions of biological and physical dynamics by developing mechanistic links between the evolution of the antarctic winter ice and snow cover, and biological habitat variability, through modeling the optical properties of the environment. The work will be carried out in the context of the Southern Ocean Experiment of the Global Ocean Ecosystem Dynamics Study (Globec), a large, multi-investigator study of the winter survival strategy of krill under the antarctic sea ice.The optical properties of snow and sea ice evolve through the winter and vary greatly both spectrally and spatially. These properties are an important element of the physical environment that strongly influences both the distribution of and the resources available to antarctic krill. The intensity of incident radiant energy and its distribution within the snow, ice, and water column environment, and the linked physical, optical, chemical, and biological processes that modulate its distribution are generally known but poorly quantified. The optical properties of snow and ice also influence snow algae, ice algae, and water column productivity, as well as visibility for both predator and prey. Furthermore, optical properties play an essential role in satellite observations as proxy indicators of geophysical sea ice parameters which permit local observations to be more accurately extrapolated in space and time, thus providing regional coverage that would otherwise not be possible. What is proposed is the deployment of an array of instrumented ice beacons, augmented by periodic ship-based and satellite observations, along with theoretical studies to create improved quantitative models with which to follow the temporal and spatial evolution of this snow and ice marine ecosystem.The specific objective is to develop a thermodynamic sea ice/ecosystem model through coupling of existing components in order to test our understanding of the system, determine its sensitivities, and to provide an organizing mechanism for integrating the Southern Ocean Globec observations. ***
