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. Five stations along six transects have been established where quasi-quarterly surface water measurements are acquired for temperature, salinity, bacteria, and 11 water chemistry parameters within 1993 to 2017 from small boats. The original data were provided as Microsoft Excel spreadsheets.

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. Five stations along six transects have been established where quasi-quarterly bottom water measurements are acquired for temperature, salinity, bacteria, and 12 water chemistry parameters within 1993 to 2007. Data are collected from small boats. The original data were provided as Microsoft Excel spreadsheets. Surface samples from these same transects are available in NCEI Accession 0156452. Ocean bottom sampling was included due to concerns related to dense cold seawater sinking to lower depths when returning to the environment. Surface water samples monitored the brackish, less dense groundwater intrusion into the marine water, which tends to float when ocean mixing energy is low. Due to new protocols in 2004 which did not require bottom samples, and because data indicated little or no difference from the surface waters, the bottom samples were discontinued in 2007.

This dataset was used as groundtruthing for low-altitude thermal infrared imagery of surface nearshore coastal waters of west Hawaii (the Big Island). Data are primarily temperature and salinity data taken in Honokohau Harbor and the adjacent oceanic waters from the surface to 5 m depth during August 2006. Additional Temperature and Salinity data plus nutrients (phosphates, nitrate, and silica) from fresh and brackish wells/ponds, harbors, and coastal waters were measured from August 2005 through May 2007.

This dataset includes chemical, discrete sample, physical and profile data collected from Hakuho Maru in the North Pacific Ocean from 1993-05-13 to 1993-05-30 and retrieved during cruise KH93-2 Leg 1 and PACIFICA_49HH19930513. These data include DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, Potential temperature (theta), SALINITY and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle. These data were collected by Shuichi Watanabe of JAMSTEC; Mutsu Institute for Oceanography (MIO) and Keisuke Taira of ORI as part of the PACIFICA_49HH19930513 dataset. PACIFICA (PACIFic ocean Interior CArbon) was an international collaborative project for the data synthesis of ocean interior carbon and its related parameters in the Pacific Ocean. The North Pacific Marine Science Organization (PICES), Section of Carbon and Climate (S-CC) supported the project.

Freshwater plumes from rain run-off into Kaneohe Bay are the focus for the investigation. Measurements of temperature and salinity from a moored, fixed-level CTD and temperature data from moored thermistors were recorded in 24 time series. Data were collected during November 2005 - March 2007 by members of the Department of Oceanography at the University of Hawaii. Current meter data from this project are provided in a separate NODC Accession (data set).

This dataset includes chemical, discrete sample, physical and profile data collected from Hakuho Maru in the North Pacific Ocean and South Pacific Ocean from 1991-09-17 to 1991-10-02 and retrieved during cruise KH91-5_2 and PACIFICA_49HH19910917. These data include DISSOLVED OXYGEN, HYDROSTATIC PRESSURE, Potential temperature (theta), SALINITY and WATER TEMPERATURE. The instruments used to collect these data include CTD and bottle.

This dataset includes surface underway data collected from small boat Kilo Kai in the Kaneohe Bay, Hawaii, North Pacific Ocean from 2013-06-13 to 2014-07-17. These data include partial pressure of carbon dioxide in the water and air, barometric pressure, sea surface salinity and sea surface temperature. The instruments used to collect these data include carbon dioxide (CO2) gas analyzer, shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement.
