Abstract. It is expected that coastal erosion, upwelling, and increased river runoff from Arctic warming will in-crease the concentration of suspended particles in the Arc-tic Ocean. Here we analyze in situ transmissometer and fluorometer data from the summers of 2003 through 2008 and bottle-derived particulate organic carbon (POC) and total suspended solids (TSS) measurements sampled in the sum-mers of 2006 and 2007 from the Canada Basin and surround-ing shelves. We divided our study area into five regions to account for the significant spatial variability and found that the highest attenuation, POC and TSS values were observed along the Beaufort shelf and the lowest values were located along the eastern shelf of the Canada Basin. We then ex-plored the correlation of POC and TSS with beam attenu-ation coefficients to assess the viability of estimating POC
