Temperature, salinity, and water chemistry data from the Comprehensive Environmental Monitoring Program of the Ocean Thermal Energy Conversion plant at Keahole, Island of Hawaii, from shallow and deep intake pipes during 1982-2017 (NCEI Accession 0001623)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 01:27 AM | Dataset Last Updated: April 24, 2018 at 12:00 AM

The Natural Energy Laboratory of Hawaii Authority (NELHA) is a state agency that operates a unique and innovative ocean science and technology park in Kailua-Kona on the island of Hawaii. It supports an Ocean Thermal Energy Conversion (OTEC) facility at Keahole Point on the west coast of the Island of Hawaii. Intake pipes at shallow (21 m) and deep (674 m) are utilized to record water characteristics. This data set includes roughly bi-weekly or monthly samples of temperature, salinity, and water chemistry, a total 16 parameters. The shallow series began in in July 1982 and the deep series in August 1988. The update to the NCEI archive in 2018 brings both series to November 2017.
