Henley participated in the Arctic PRIZE (PRoductivity in the seasonal Ice ZonE). This project investigates the impact of sea changes in Antarctica. She also takes part in CHaOS (Changing Arctic Ocean Seafloor). It focuses on uncovering the effect of the melting ice cover on different areas in marine life. Henley conducts her own research too: ecosystem change in the Arctic, nutrient and carbon dynamics and the marine nitrogen cycle. She is part of the Southern Ocean Observation System (SOOS). Henley is also part of Women in Ocean Science (WOS) an organization aiming to support women in the field of ocean science and to let them be heard.
