Scientific breakthrough: First images of freshwater plumes at sea

April 3, 2021

March 2021: University of Hawaii: The first imaging of substantial freshwater plumes west of Hawaiʻi Island may help water planners to optimize sustainable yields and aquifer storage calculations. University of Hawaiʻi at Mānoa researchers demonstrated a new method to detect freshwater plumes between the seafloor and ocean surface in a study recently published in Geophysical Research Letters.

The research, supported by the Hawaiʻi EPSCoR ʻIke Wai project, is the first to demonstrate that surface-towed marine controlled-source electromagnetic (CSEM) imaging can be used to map oceanic freshwater plumes in high-resolution. It is an extension of the groundbreaking discovery of freshwater beneath the seafloor in 2020. Both are important findings in a world facing climate change, where freshwater is vital for preserving public health, agricultural yields, economic strategies, and ecosystem functions.
