The voyage took place between June 30 and July 29, 2021 departing from Darwin (NT) and arriving in Hobart (TAS).Water samples collected during the voyage were analysed in the ship’s hydrochemistry laboratory for nutrients, dissolved oxygen, and salinity. Five nutrients were determined: silicate (Si(OH)4), phosphate (PO4), nitrate + nitrite (NOx), nitrite (NO2) and ammonium (NH4). Certified reference materials for nutrients in seawater (RMNS) were within 3% of their certified values. See table for the CTD deployment versus measured RMNS values.
