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.

High-resolution measurements of waves, currents, water levels, temperature, salinity and turbidity were made in Hanalei Bay, Kauai, Hawaii during the summer of 2006. A series of bottom-mounted instrument packages were deployed in water depths of 10 m or less. These data support the ongoing process studies being conducted as part of the US Geological Survey Coastal and Marine Geology Program's Pacific Coral Project. Finalized data were provided in ASCII format for the waves, currents, and water levels. Other variables are summarized in graphics and described in a technical report.

Field data collection was conducted for the U.S. Army Engineer District, Pacific Ocean, Honolulu (POH), during August 9 - September 14, 2005, off Kailua, Lanikai, and Waimanalo, Oahu, Hawaii. Wave and current data were collected at five fixed locations using bottom-mounted RD Instruments Workhorse, 1.2 MHz, ADCPs (Acoustic Doppler Current Profilers) and Sontek Hydra ADVs (Acoustic Doppler Velocimeters). The ADCPs include wave measurements. 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. Deployments were made on 10 August and 13 September. June.

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.

Freshwater plumes from rain run-off into Kaneohe Bay is the focus for the investigation. Measurements in this data set are currents as measured by an moored Acoustic Doppler Current Profiler (ADCP) and a Nortek current meter. Data were collected during November 2005 - March 2007 by members of the Department of Oceanography at the University of Hawaii. The ADCP sensor includes temperature at the transducer depth of 13 m. The Nortek current meter included ancillary measurements including temperature and pressure. Temperature and salinity data taken at 24 stations as part of this project are available from NODC accession 0039532.

EM300 and EM3002D multibeam data were collected from 8 Nov to 13 Nov 2006 aboard NOAA Ship Hi'ialakai at Maui Island and Hawaii's Big Island in the Central Pacific during cruise HI-06-14. These multibeam data were collected using SAIC ISS-2000 software in the Generic Sensor Format and processed using SABER editing software. Surface sound velocity values were supplied by a Seabird SBE-45 MicroTSG and a SBE-38 remote temperature probe. Sound velocity corrections from a Seabird 911 CTD sensor and motion corrections from a POS-MV vertical reference were applied to the data in real time. Predicted tides were applied to the data in real time using tide zoning and predicted tides supplied by NOAA's National Ocean Service Center for Operational Oceanographic Products and Services (CO-OPS). Horizontal accuracy is 20m (no differential GPS correctors applied), vertical accuracy is depth dependent (~1% of water depth), WGS84 datum. These data are not to be used for navigation. Depths mapped range from -20 to -1000 m.
