Through various funding channels, the Department of Oceanography at the University of Hawaii (UH) has maintained a Datawell Mark 2 Directional Waverider Buoy roughly 4 miles southeast of Mokapu Point, Oahu in roughly 100 m ocean depth since 9 August, 2000. It is located at the seaward edge of Kailua Bay, Windward Oahu. The buoy is a 0.9 m metallic floating sphere with a combination of a bungee and chain anchoring system. The long-term availability of this mooring is uncertain. The directional waverider measures the horizontal and vertical components of acceleration of the buoy, which rides up and down with the waves as it floats on the surface. The sampling rate is 1 Hz and the acquisition time is 20 minutes. From the accelerations of each acquisition time, spectra of energy by frequency and direction are derived. In addition, significant wave height and dominant wave period are calculated. The information is relayed to a shore data logging platform every 30 minutes. The Coastal Data Information Program (CDIP) are the primary stewards of the real-time data while UH handles maintenance duties.

ADCP data were collected by sensors from seven deployments within 2004-2007 on the HALE-ALOHA mooring, a location about 100 km north of Oahu, Hawaii, USA. The HALE-ALOHA mooring supports the Hawaii Ocean Time-series program. The ADCPs were one of many instruments deployed for the Multi-disciplinary Ocean Sensors for Environmental Analyses and Networks (MOSEAN) project, lead by the Ocean Physics Laboratory (OPL) of the University of California at Santa Barbara. The MOSEAN project is funded by the National Oceanographic Partnership Program (NOPP). The main goal of MOSEAN is to develop and test relatively small, lightweight optical and chemical sensors for autonomous deployment. Each deployment lasted around six months. No data are available for deployment 1. Data quality is questionable for deployments 3-6 and thus are not archived at NODC. Only deployment 2 is of good quality and in the archive. The data were quality controlled by the OPL. MOSEAN SEACAT CTD data are provided in a separate NODC accession, 0115703.

A pair of High Frequency Wellen radars (WERA) shore-based at southwest Oahu (Ko'Olina) and northwest Oahu (Kaena), Hawaii measured surface currents over a nine-month period from September 2002 to May 2003. Vector currents were combined from measured radial currents on a 5-km cartesian grid by least-square fitting zonal and meridional components to radial components within a 5-km search radius. The resultant hourly data set was calibrated and quality controlled. Data provided by the originators as a MATLAB file. NODC has exported the data into ASCII files.

Field data collection was conducted for the U.S. Army Engineer District, Pacific Ocean, Honolulu (POH), during 23-29 August 2007, in the vicinity of the Natatorium, a World War I memorial in Kapiolani Park, Honolulu, Oahu, Hawaii. Three bottom mounted instruments were deployed to measure waves and currents. A Nortek AWAC (1 MHz) acoustic current profiler was placed seaward of the reef, centered off the Natatorium, in about 5m depth. An RD Instruments ADCP (1.2 MHz) current profiler was mounted on the channel bottom near the entrance, in about 3m depth. The third unit was a Nortek Aquadopp current profiler (2 MHz) was placed in a small hole in the reef, about 35m seaward of the Natatorium pool outer wall in a nominal depth of 1.5m. The first two gauges recorded directional waves and current profiles, the Aquadopp only recorded current profiles. Four inexpensive current drogues (drifters) were designed and built at the CHL Field Research Facility (FRF) that used GPS tracking and radio telemetry for positioning.

Sediment in the vicinity of the Barbers Point (Honouliuli) ocean outfall were sampled from 1986-2002. To assess the environmental quality, sediment grain size and sediment chemistry were measured. Stations were located both within and on the boundary of the zone of initial dilution (ZID) and at distances of 1.2 to 2 km from the ZID boundary.

Spatial and temporal measurements of meteorologic, oceanographic, and sedimentological data were made during the 2010-2011 winter in Pelekane and Kawaihae Bays, on the Kohala coast of the northwest side of the Island of Hawaii. This data set consists of the oceanographic measurements at depths of 2 to 15 m made by the US Geological Survey. Bottom-mounted oceanographic instrument packages were deployed along the 5-m and 15-m isobaths, as well as a cross-shore array in the central region of Kawaihae Bay. This cross-shore array included three bottom-mounted oceanographic instrument packages on the 2-m, 5-m, and 15-m isobaths, and two moorings on the 5-m and 15-m isobaths.
