Thorium and Uranium Radioisotope Data from HLY-02-03. Version 1.0

This data set includes data corresponding to samples collected by the Moran Geochemistry Lab on the second leg aboard the United States Coast Guard Cutter (USCGC) Healy on the SBI Phase II investigation in the Chukchi and Beaufort Seas from 21 July 2002 to 17 Aug 2002 (WAGB-20). Data are organized by station and sample depth, with station position (latitude and longitude) also included. This data set includes the following radio-isotopes: 234Th, 228Th, and 238U. The thorium data include dissolved, suspended particulate, and large particulate values in units of disintegrations per minute per liter (dpm/L). The uranium data were derived from salinity (salinity ppt * 0.069 dpm/ppt = 238U dpm/L ; Chen et al, 1986). This data set also includes values for large particulate organic carbon (POC) and large particulate organic nitrogen (PON) .

本数据集包含 Moran地球化学实验室于2002年7月21日至8月17日期间，在美国海岸警卫队“希利”号破冰船（USCGC Healy，舷号WAGB-20）执行SBI二期调查的楚科奇海与波弗特海第二航段中采集的样本对应数据。数据按站位和样本深度组织，同时包含站位坐标（纬度和经度）。本数据集包含以下放射性同位素（radio-isotopes）：234Th、228Th和238U。钍数据包含溶解态、悬浮颗粒态和大颗粒态的数值，单位为每分钟每升衰变数（disintegrations per minute per liter，dpm/L）。铀数据由盐度计算得出（盐度ppt ×0.069 dpm/ppt = 238U dpm/L；Chen等，1986）。本数据集还包含大颗粒有机碳（POC）和大颗粒有机氮（PON）的数值。
