Submarine groundwater discharge (SGD) dataset from Kīholo Bay, Hawai’i Island from 2014-2016. Radon data (Bq/m^3) were collected using the SGD Sniffer (Dulai et al., 2016), an autonomous gamma spectrometer. Salinity was derived from specific conductivity collected by an onboard CTD Diver. SGD (cm/day) was calculated using a radon mass balance following methods described in Dulaiova et al., 2010.

‘Ike Wai:

In 2016, University of Hawai‘i launched the Hawai‘i EPSCoR ‘Ike Wai project supported by the National Science Foundation (Award # OIA-1557349) The five-year project uses integrated research, education, and community engagement efforts aimed to ensure Hawai‘i’s future water security and promote resource management within the state that is sustainable, responsible, and data-driven.

To save space on Hydroshare, all ‘Ike Wai project files are stored at the University of Hawai‘i and linked here. Please use the following link(s) to see the files for this resource.
