Thorium and Uranium Radioisotope Data from HLY-02-01. Version 1.0

This data set includes data corresponding to samples collected by the Moran Geochemistry Lab on the first leg of the SBI Phase II investigation in the Chukchi and Beaufort Seas from 09 May 2002 to 12 June 2002 aboard the U.S. Coast Guard Cutter (USCGC) Healy (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 includes 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) .
