Dataset: Dissolved organic compound (DOS, DOP, DOBr, DOI) depth profiles collected at the Bermuda Atlantic Time Series Station (BATS) in August 2019 and at the Hawaii Ocean Time Series Station Aloha in July 2021

This dataset contains the dissolved organic sulfur (DOS), dissolved organic phosphorus (DOP), dissolved organic bromine (DOBr) and dissolved organic iodine (DOI) data from solid-phase extracted (Agilent Bond Elut PPL) samples following the methods described in Gonsior et al. (2024) (doi:10.1039/D3VA00361B) for DOS and DOP and in Powers et al. (2024) (doi: 10.1016/j.scitotenv.2023.169292) for dissolved organic bromine (DOBr) and dissolved organic iodine (DOI).  

Water samples were collected using the ship's CTD profiler and 12 L Niskin bottles. 10 L water samples from each depth were then transferred into 5 gallon polycarbonate water bottles, passed through combusted 0.7 micron glass fiber filters and extracted.

The solid-phase extracted methanolic sample was dried under nitrogen and re-dissolved in pure water prior to DOS, DOP, DOBr, and DOI analysis by ICP-MS. Samples for DOBr and DOI analysis were also passed through silver cartridges prior to analysis to remove residual halides. DOS and DOP were analyzed by ICP-MS/MS using oxygen as the reaction gas and DOBr and DOI were analyzed by ICP-MS/MS with no gas in the Octopole Reaction System.
