Kellie O'Connor worked as an intern at Pacific Northwest National Laboratory to contribute to Tethys, an online database collecting documents on environmental effects of offshore renewable energy development. She defined interactions between renewable energy devices and environmental receptors, and applied this information to documents in Tethys. Her work will help technology developers minimize environmental impacts, regulators make permitting decisions, and researchers identify areas for further study. Tethys currently hosts over 2,500 documents categorized by stressors devices cause and receptors affected.
