    "title": "NCCOS Assessment: Post-hurricane assessment of chemical contaminants in nearshore waters and marine sediments at two St. John, U.S. Virgin Islands (USVI) National Parks, 2021-08-16 to 2022-03-07 (NCEI Accession 0303533)",
    "description": "Marine sediment and water column samples were collected in nearshore habitats around the island of St. John, USVI during two sampling trips in late 2021 and early 2022 and following the landfall of two Category 5 hurricanes, Irma (landfall 2017-09-06) and Maria (landfall 2017-09-20). Marine sediment samples were analyzed for trace metals, organochlorine pesticides, polychlorinated biphenyl (PCB) compounds, polycyclic aromatic hydrocarbons (PAH), butyltins, pharmaceuticals and personal care products (PPCP) and biological (Clostridium perfringens) contaminants. Water column samples were filtered over solid phase extraction columns (Oasis HLB, Waters Corp.) and analyzed for pharmaceuticals and personal care products, including UV filters (sunscreens). We also collected seawater turbidity, pH, temperature, salinity and conductivity measurements at each embayment in 2021. Sediment interstitial water (porewater) was used in a sea urchin embryo development toxicity (SUETOX) assay to determine the relative benthic health at each site. Water samples for contaminant chemistry and sediment porewater for the SUETOX assay were collected between 2021-08-16 and 2021-08-21 while sediment samples for contaminant analyses were collected 2022-01-22 \u2013 2022-03-07. Chemical analyses of the seawater and sediment samples occurred between 2022-03-30 and 2023-11-13. Total organic carbon and grain size analyses were also performed on the sediment samples from 2022, as those data can influence the results of each of those tests.",
