Vessel-mounted acoustic-doppler current profiler (ADCP) and surface-wind data from the National Park of American Samoa, Tutuila, American Samoa, 2015 currentmeter Spatial surveys of water column currents and surface winds were conducted from February 17 to 20, 2015, off the north coast of the island of Tutuila, American Samoa. These data were collected using an acoustic-doppler current profiler (ADCP) and a meterological sensor in support of a study on the coastal circulation patterns within and in the vicinity of the National Park of American Samoa.

Lagrangian ocean surface drifter deployments off the National Park of American Samoa, Tutuila, American Samoa, 2015 GPS Satellite-tracked, DGPS-equipped Lagrangian surface-current drifter deployments were conducted over 12 weeks between 14 April and 7 July 2015 at various locations within and offshore of the National Park of American Samoa study area to track surface currents. The drifters internally logged their location every 1 minute, and they transmitted their positions to satellites every 5 minutes. A drogue was attached to the drifters at 1 m below sea level in order to track the currents at that depth. Joshua Logan

Time-series oceanographic data from the National Park of American Samoa, Tutuila, American Samoa, 2015 Moorings - Tripods Time-series data of water surface elevation, wave height, and water column currents, temperature, and salinity were acquired for 150 days between 13 April and 14 July 2015 off the north coast of the island of Tutuila, American Samoa in support of a study on the coastal circulation patterns within and in the vicinity of the National Park of American Samoa.
