Update: Buoys deployed on 3/31/2017. See chart below for exact locations.
NREL researchers are undertaking a multi-year research project to collect measurements at various locations around the United States to better understand wave and tidal characteristics. Oregon was selected as one of eight sites after an exhaustive study to determine the most suitable locations along the coastline. The research project is designed to better understand the wave resource characteristics in regions that have a high-density wave resource. Researchers selected measurement locations in shallow water because the data will be used to validate state-of-the-art wave resource models. Although there are many buoys along the U.S. coastline, few of these buoys are in shallow water along the West Coast. The Oregon measurements will provide critical inputs for validating models and developing a wave classification scheme that accurately represents the U.S. West Coast.
The measurement in Oregon is along the central coast, offshore of Lakeside and Reedsport. The measurement will collect data for 1 year, at which time all measurement equipment will be removed. Equipment will include two Datawell MKIII wave buoys, as shown in Figure 2. The locations for the measurements are shown below and illustrated in Figure 1. One buoy will be installed at the Reedsport location, and another buoy will be deployed at the Lakeside location.

The map below shows a section of the central Oregon coastline near Reedsport and Lakeside, where the wave measurements are occurring. The two yellow balloons indicate the measurement locations. The cyan balloon shows the location of an existing deep-water buoy. The green box indicates the location of REFSSA #4 from Part 5 of the Oregon Territorial Sea Plan.

Both of the Datawell MKIII buoys will be deployed as shown in Figure 2. The buoy is approximately 3’ in diameter and weighs nearly 500 lbs. It floats in the ocean, half-submerged, within an anti-spin triangle with an antenna on top to enable cellular communication. For this deployment, the buoy will be moored and anchored as shown in Figure 3. The anchor weight may be chain (as illustrated) or several railroad wheels, depending on the ocean dynamics in Oregon. At night time, the buoy will emit a yellow color Coast Guard compliant flashing light.
