This research program will exploit a newly developing methodology to resolve a controversy regarding the cycling of carbon, oxygen, and nitrogen at the sediment-water interface. These studies will serve as an indicator of pelagic-benthic coupling and the availability and fate of fixed carbon on the extensive shallow- water shelves in the Arctic. This study will also provide cross comparison between shipboard sediment incubations and in-situ benthic flux studies to monitor fluxes of oxygen, carbon dioxide, and nutrients with overlying bottom water. This program will be conducted in conjunction with previously funded research to evaluate the role of the Arctic shelves in global biogeochemical cycling. These complimentary programs will take place on-board the R.V. Alpha Helix in the Chukchi and Beaufort Seas during the summer of 1992.

该研究计划将利用一种新开发的方法来解决有关沉积物-水界面碳、氧和氮循环的争议。 这些研究将作为中上层-底栖耦合以及北极广阔的浅水陆架上固定碳的可用性和归宿的指标。 这项研究还将提供船上沉积物孵化和原位底栖通量研究之间的交叉比较，以监测上覆底水的氧气、二氧化碳和营养物的通量。 该计划将与之前资助的研究一起进行，以评估北极陆架在全球生物地球化学循环中的作用。 这些免费项目将在房车上进行。 1992 年夏天，楚科奇海和波弗特海的阿尔法螺旋。
