Description:
Halogenated natural products are organic compounds produced by marine bacteria and other marine organisms, as well as created anthropogenically through water chlorination and production as industrial compounds. These compounds can exhibit toxicity, bioaccumulate in the environment, and perform important roles in the regulation of the tropospheric and stratospheric ozone. Anticipated effects of climate change in coastal zones such as increased runoff and reduction in multi-year sea ice are expected to increase the production rates of these compounds, which will increase the impact these compounds have on biogeochemical cycles and ecosystems. These compounds are understudied, particularly in marine Arctic environments. This project will share prospective data on both di- and tri- bromoanisoles and bromophenols from the Western Arctic collected on a May-June 2021 cruise in the Beaufort and Chukchi Seas, as well as data to be collected from the mid-latitude estuary of Long Island Sound. These data help to close the gap in measurements of HNPs and inform future studies.
