Marine waters
DEQ has been working with a scientific technical workgroup to assist in developing a methodology for assessing the impacts of ocean acidification and marine dissolved oxygen in Oregon’s territorial waters for use in the 2024 assessment. While DEQ and the workgroup have made significant process in this effort, the work is complex, and more time is needed to develop a draft methodology. For this reason, DEQ plans to hold a separate public process for marine waters in the spring/summer 2023, including a separate methodology comment period, webinar, and Call for Data. Visit
Assessment Methodology Updates web page for more information.
