Summary

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.

Purpose

The measurements of waves and water levels from these instrument deployments provide information on the variability of waves on the coral reefs of southern Ofu. These data will be used to study the transformation of waves over the reef and how this process contributes to water levels, runup and the potential for flooding of the coast. They will also be used to support analyses into submarine groundwater dynamics on this reef.
