Pelagic-Benthic Coupling at Euthrophic and Oligotrophic Sites in the Marine Environment

白令海北部和楚科奇海南部的特点是初级和次级生产力都很高。最近在美国水域的研究表明，食物供应、沉积物的异质性和粉土/粘土含量以及水温是影响底栖生物过程的主要因素。苏联科学家过去的研究表明，苏联水域的生物量也很高，尽管很少有研究涉及影响高生物量种群的过程。在美国和苏联联合巡航期间，格雷布迈尔将检验这样一种假设，即白令海北部和南部楚科奇海浅大陆架上的直接远洋-底栖生物耦合增强了底层底栖动物的底栖生物生产和碳循环。为了进行比较，苏联水域的站点将以类似于之前在美国水域采样的方式进行采样。研究结果将极大地提高对白令海和楚科奇海内部碳和氮循环的理解。这项研究计划补助金是通过妇女研究机会方案授予的。

The northern Bering and southern Chukchi Seas are characterized by high primary and secondary productivity. Recent research in U.S. waters indicates that food supply, sediment heterogeneity and silt/clay content, and water temperature are major factors influencing benthic processes. Past research by Soviet scientists indicates that biomass is also high in Soviet waters, although few studies have addressed the processes influencing the high-biomass populations. During a joint US/USSR cruise, Grebmeier will test the hypothesis that direct pelagic- benthic coupling on the shallow continental shelf of the northern Bering and southern Chukchi Seas enhances benthic production and carbon cycling in the underlying benthos. For comparison, stations in Soviet waters will be sampled in a manner similar to those previously sampled in U.S. waters. Results will greatly enhance the understanding of carbon and nitrogen cycling within the Bering and Chukchi Seas.
