A Multidisciplinary Analysis of Shelf-Derived Carbon Dispersal Within the Arctic Basins, as Sampled by Submarine

溶解有机碳（DOC）是北冰洋有机碳的主要储存库，因此这一储存库也可能是大气二氧化碳的重要汇。因此，表征控制DOC浓度和命运的过程对于定量了解北冰洋碳循环至关重要。1995年3月至5月，美国海军潜艇沿着波弗特海、楚科奇海、东西伯利亚海和拉普捷夫海的大陆架断裂进行巡航，将收集和分析大约1000个样本，以测定营养物、DOC和溶解无机碳（DIC）的浓度。在巡航过程中，大约100个水样将被分析溶解氧、碱度和叶绿素/色素。这些数据将用于确定各地区DOC的来源、微生物再矿化过程的速率以及氮和碳循环之间的耦合。

9423349 Whitledge Dissolved organic carbon (DOC) is the major reservoir of organic carbon in the Arctic Ocean, and as such this reservoir may also serve as an important sink for atmospheric carbon dioxide. Characterization of the processes controlling the concentrations and fates of DOC is therefore critical for gaining a quantitative understanding of the Arctic Ocean carbon cycle. During a U.S. Navy submarine cruise in March-May 1995 along the shelf breaks of the Beaufort, Chukchi, East Siberian, and Laptev Seas, approximately 1,000 samples will be collected and analyzed for concentrations of nutrients, DOC, and dissolved inorganic carbon (DIC). Approximately 100 water samples will be analyzed for dissolved oxygen, alkalinity, and chlorophyll/phaeopigments during the cruise track. These data will be used to determine the sources of DOC to the various regions, the rates of microbial remineralization processes, and the coupling between nitrogen and carbon cycling.
