Rosenberger, K.J., Cheriton, O.M., and Storlazzi, C.D., 2020, Cross-reef wave and water level data from coral reef environments (ver. 2.0, March 2021): U.S. Geological Survey data release,


Time series data of water surface elevation and wave height were acquired at ten locations for 517 days (in three separate deployments) off the north coast of Roi-Namur Island, Kwajalein Atoll, Marshall Islands, in support of a study on the coastal circulation patterns and the transformation of surface waves over the coral reefs. The relative placement of sensors on the reefs were as follows: ROI13W1 and ROI13E1 – fore reef ROI13W2 and ROI13E2 – outer reef flat ROI13W1 and ROI13E1 – middle reef flat ROI13W1 and ROI13E1 – inner reef flat

The continuous measurements of waves, currents, tides from these instrument deployments, provide information on nearshore circulation and the variability in these hydrodynamic properties over the coral reefs of Kwajalein. These data will be used to study the transformation of waves over the reef and how this process contributes to the shoreward migration of coral reef-derived carbonate sediment.
