ABSTRACTOCE-0125313The study will use a series of aircraft flights out onto Artic ice fields in the SBI work areas during March and April of years 2003 and 2004 to obtain hydrographic, nutrient and other chemical tracer distributions representative of end-winter - early spring conditions of the underlying water column. These late winter samples will be used to complement additional Shelf Basin Initiative (SBI) cruise hydrography in this region. Hydrography (temperature, salinity, density) will be profiled from the ice surface to 250m or the sea floor depending on water depth. Additional samples will be taken for nutrients, d 18O and possibly dissolved inorganic carbon parameters. The study areas will include transects out from Point Barrow (Alaska) to 1650 W, a transect across the shelf-slope break at 1540 W, and a transect across the shelf break at 1510 W, along the location of a current meter mooring line which is deployed as part of the larger SBI experiment.

本研究将在2003年和2004年的3月和4月期间，利用一系列的飞机飞行到SBI工作区的北极冰原上，以获得代表底层水柱冬末春初条件的水文、营养物和其他化学示踪剂分布。这些晚冬样本将用于补充该区域额外的陆架盆地倡议巡航水文学。水文（温度、盐度、密度）将根据水深从冰面到250米或海底进行剖面测量。将采取额外的样品，用于营养物、d18O和可能的溶解无机碳参数。研究区域将包括从巴罗点（阿拉斯加）到1650 W的横断面、1540 W处穿过陆架坡折的横断面和1510 W处穿过陆架坡折的横断面，沿着流速计系泊线的位置，该系泊线是作为更大SBI实验的一部分部署的。
