Ofu, American Samoa, wave and water level data, 2020

Time series data of wave height and water surface elevation were acquired for 399 days at four locations on the southern reef of Ofu, American Samoa, in support of a study on submarine groundwater dynamics on this reef within the National Park of American Samoa’s Ofu Unit. The relative placement of sensors on the reef were as follows: OFU20E03 – mid reef at East site; OFU20E04 – inner reef at East site; OFU20W03 – mid reef at West site; OFU20W04 – inner reef at West site.
