opposing trends of fractionation with changing Nb and Zr abundances points to different controlling particles, adsorption mechanisms, or biogeochemical effects that require further work to unravel (Firdaus et al. 2011; Niu 2012). The compiled trace element chemistry of major rivers can place important baseline constraints on terrestrial fractionation processes and are used to calculate element fluxes to the oceans. However, very few rivers have been fully characterized for a comprehensive suite of dissolved ultra-trace elements (Gaillardet et al. 2014). The Ottawa River in Canada is one of the best characterized examples due to it being the source of the National Research Council – Conseil national de recherches Canada (NRC-CNRC) series of SLRS natural river water certified reference materials (CRM). The SLRS CRM are frequently used for natural water data quality assurance/quality control (QA/QC) in laboratories across the globe (Yeghicheyan et al. 2001; Barroux et al. 2006; Lawrence et al. 2006a; Dick et al. 2008; Bayon et al. 2011; Heimburger et al. 2013; Yeghicheyan et al. 2013; Hoang et al. 2019). Consequently, these data are opportunistically taken as representative of the trace element and isotopic composition of the Ottawa River for global compilation studies (Archer and Vance 2008; Vance et al. 2008; Gaillardet et al. 2014). However, the SLRS CRM series represent only a well-characterized composition of the river at a singular location and time. The only targeted trace element study of the Ottawa River with a wide spatial coverage predated the development of low-level, high-precision mass spectrometry techniques (Merritt 1975). There are two primary facets of this study: (1) characterization of ultra-trace elements in the dissolved load of the Ottawa River and selected tributaries near to and upstream of the SLRS CRM series sampling sit
