Deep Submarine Fresh Water: A New Resource for Volcanic Islands?

The discovery of large freshwater reservoirs off Hawaii suggests that other volcanic islands may have similar resources, which could help meet water demands amid population growth and climate change.

Marine electrical imaging reveals novel freshwater transport mechanism in Hawai‘i

I recently presented the results of this project in the Friday seminar (TGIF) of Hawaiʻi Institute of Geophysics & Planetology, School of Ocean and Earth Science Technology, University of Hawaiʻi.

My TGIF talk can be found in this link:

The paper associated with these findings will soon be published in Science Advances (expected publication date: 11.25.2020).

CSEM imaging of large-scale seafloor-to-ocean surface freshwater plumes

“Marine Electromagnetic Imaging and Volumetric Estimation of Freshwater Plumes Offshore Hawai’i”. In this paper, we present electromagnetic imaging of seafloor-to-ocean surface freshwater plumes (Attias et al., 2021, GRL: https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2020GL091249).
