Cation and suspended sediment concentrations from the Mackenzie River and Estuary, Canada, September 2022
Dissolved element concentrations, dissolved stable carbon isotope ratios (δ13C), salinity measurements, and suspended particulate matter (SPM) concentrations from the Mackenzie River and estuary. River water and SPM samples were collected between the 11th and the 18th of September 2022. Samples were taken from the surface of the water column and at depth. Individual sample locations (latitude and longitude) are provided in the data file. In total, 18 water and SPM samples were collected from 11 different localities. Samples were collected to span a large salinity range (0.15-29 P.S.U.). Dissolved element concentrations provided: aluminium, barium, calcium, iron, potassium, magnesium, manganese, sodium, sulphate, silicon, and strontium.

Provenance & quality
Salinity measurements were conducted using a ProDSS salinity probe (YSI) in-situ. Element concentrations were determined via inductively-coupled plasma optical emission spectroscopy (ICP-OES) on an Agilent 5100 at the Department of Earth Sciences (University of Cambridge). Element concentration uncertainties were determined via repeated measurements of the SPS-SW2, SLRS-6 and IAPSO standards. Suspended particulate matter (SPM) concentrations were made using the volume of water collected and the mass of dried solids. Dissolved inorganic carbon (DIC) isotope measurements were made using a Thermo Gas Bench attached to a Delta V Mass Spectrometer.
