Datawell - Model DWR-G4 -Wave Monitoring Buoys

Datawell’s smallest directional wave measuring buoy. With a 0.4 m diameter mini-buoy version Datawell completes its range of GPS buoys: DWR-G9, DWR-G7 and DWR-G4, with 0.9 m, 0.7 m and 0.4 m diameters, respectively. Just like its larger equivalents the DWR-G4 relies on the Datawell principle of measuring waves with a single Global Positioning System receiver (GPS). By now this technique is well-established in oceanography as evidenced by several publications and well-pleased users in the field.
