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

白令海北部和楚科奇海南部具有较高的初级和次级生产力。最近对美国水域的研究表明，食物供应、沉积物异质性和淤泥/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。在美苏联合巡航期间，Grebmeier将测试在白令海北部和楚科奇海南部的浅层大陆架上直接的上层海洋-底栖生物耦合的假设，该假设增强了底栖生物的生产和底层底栖生物的碳循环。为了比较，苏联水域的监测站将以类似于以前在美国水域采样的方式进行采样。研究结果将大大提高对白令海和楚科奇海碳氮循环的认识。这项研究计划资助是通过妇女研究机会项目授予的。

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.
