US-Norway Cooperative Research: Evaluation of Critical Depth Hypothesis for Phytoplankton in Polar Waters

关于“评价临界深度假说”的建议， 极地沃茨中的浮游植物”， 海洋资源研究所，斯克里普斯海洋学研究所， 位于圣地亚哥的加州大学， 挪威特隆赫姆大学生物站由 NSF。 霍姆-汉森博士建议花两个月的时间主要分析数据 他和Sakshaug博士在极地和北极的无数次航行中 在过去的七年中，以及数据都有 在实验室中产生的，这是必不可少的解释他们的 现场数据 他们的计算机化数据库同时包括 获得的物理-生物-光学特性信息 在垂直剖面中，在水柱的上部200米处。 的 研究人员希望建立一个模型， 浮游植物的生理和平均辐照度 电池受到垂直混合过程的影响而暴露。 他们应在一般框架内解释数据， 临界深度假说最早由Sverdrup于1953年提出， 希望他们的大数据库应该提供一个更现实的 这一概念的形成。

This proposal on "Evaluation of Critical Depth Hypothesis for Phytoplankton in Polar Waters" between Dr. Osmund Holm-Hansen of the Institute of Marine Resources, Scripps Institute of Oceanography, University of California at San Diego, and Dr. Egil Sakshaug of the Biological Station, University of Trondheim, Norway, is sponsored by NSF. Dr. Holm-Hansen proposes to spend two months primarily analyzing data he and Dr. Sakshaug have acquired in numerous cruises in both polar regions during the past seven years, as well as data both have produced in the laboratory which is essential to interpreting their field data. Their computerized data bases consist of simultaneously acquired information on physical-biological-optical characteristics in vertical profiles in the upper 200 m of the water column. The investigators wish to model the dynamic interaction between growth and physiology of the phytoplankton and the mean irradiance to which the cells are exposed as influenced by vertical mixing processes. They shall interpret data within the general framework of the Critical Depth hypothesis first described by Sverdrup in 1953, expecting that their large data base should provide a more realistic formulation of this concept.
