Rosenberger, K.J., Cheriton, O.M., and Storlazzi, C.D., 2020, Cross-reef wave and water level data from coral reef environments (ver. 3.0, January 2024): U.S. Geological Survey data release,


Time series data of water surface elevation and wave height were acquired at ten locations for 518 days (in three separate deployments) off the south coast of Kwajalein Island, 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: KWA13W1 and KWA13E1 – fore reef KWA13W2 and KWA13E2 – outer reef flat KWA13W1 and KWA13E1 – middle reef flat KWA13W1 and KWA13E1 – 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.
