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 deep (675 m) and shallow (20 m) are utilized to record water characteristics. This data set includes roughly bi-weekly samples of temperature, salinity and water chemistry.

Cold water was collected via a 675 meter deep one meter diameter HDPE pipe
located 1.6 km from shore. Water velocities are slow enough that no
significant heating occurs by friction. Warm water is taken from a 28 inch
pipe 20 meters deep located near shore.
Each data value is a separate sample that is corrected against the
calibration of the machine it is run on. The instrumentation is calibrated
against a set of standards that are either solutions formulated by our
chemists or against a standard that comes in a sealed glass ampoule from a
certified lab on the mainland or Europe. A set of samples (15-50) are run on
the calibrated instrumentation (machines) over a period of about 2-8 hours
depending on the parameter measured.
The time of day varies, although the measurement is usually determined
between 11:00 a.m. to 4:00 p.m. Most of the samples are run fresh and not
preserved in any way, except DO's. We measure dissolved oxygen using the
Winkler Titration method, so the samples are preserved with a two chemical
process immediately after the sample is taken. The shallow intake was
between 65-70 ft. It is actually closer to 45-50 ft., which is still
probably well below influence of sunlight.
