Description: This data set is predominantly sourced from the National Water Quality Monitoring Council (https://www.waterqualitydata.us/portal) and contains water quality data for the United States as well as climate and other ancillary data. This data was used to develop a model to explain groundwater dissolved organic carbon concentrations in the manuscript "Changes in global groundwater organic carbon driven by climate change and urbanization". Units for variables are included in the file "Units for Variables". --- National Water Quality Monitoring Council water chemistry data (https://www.waterqualitydata.us/portal) was obtained from: Chapelle, F.

Description: The cores and dredges described in this report were taken during the VEMA 7 Expedition from May until September 1955 by the Lamont Geological Observatory, Columbia University from the R/V Vema. A total of 78 cores were recovered and are available at Lamont-Doherty Earth Observatory for sampling and study.

Description: Total Suspended Particulate (TSP) aerosol samples were collected daily during the Stratospheric ozone: Halogen Impacts in a Varying Atmosphere (SHIVA) cruise (FS Sonne, SO218) during 16 - 28 November 2011 through the South China and Sulu Seas. The samples were collected by Birgit Quack and Anke Schneider of GEOMAR, Kiel, Germany. The aerosol sampler was situation on the roof of the ship's wheelhouse and collection time for each sample varied between 13.0 and 24.7 hours. Samples were extracted with ultrapure water and the major ions Na+, NH4+, Mg2+, K+, Ca2+, Cl-, NO3-, SO42-, oxalate and Br- were determined by ion chromatography (IC). Total soluble iodine (TSI) was determined by inductively coupled plasma - mass spectrometry (ICP-MS) and iodide (I-) and iodate (IO3-) were determined by IC-ICP-MS. The dataset contains the atmospheric concentrations of all measured soluble major ions (in nmol m-3) and iodine species (in pmol m-3). The data for iodine species are reported in “The influence of collection substrate and extraction method on the speciation of soluble iodine in atmospheric aerosols”, Chan Yodle, Alex R. Baker, in preparation for Analytical and Bioanalytical Chemistry.
