High-resolution measurements of currents, water levels, temperature, salinity and turbidity were collected in the marine portion of Kaloko-Honokohau National Historical Park (KAHO), Hawaii, in 2004. These data are intended to help researchers better understand the dynamics of the oceanographic environment in the park's coastal waters. Measurements were made through the emplacement of a series of bottommounted instruments deployed in water depths less than 15 m. This study was conducted in support of the National Park Service by the U.S. Geological Survey (USGS) Coastal and Marine Geology Program's Coral Reef Project. The purpose of these measurements was to collect hydrographic data to learn how currents and water column properties such as water temperature, salinity and turbidity in the vicinity of nearshore coral reef systems vary over the Trade wind season. These measurements support the ongoing process studies being conducted under the Coral Reef Project; the ultimate goal is to better understand the transport mechanisms of sediment, larvae, pollutants and other particles in coral reef settings.
