Wave measurements are an indispensable part of any MetOcean or Limnology project. The Obscape Wave Buoy is based on recent advances in battery and solar power, sensor and data technology, ensuring a rugged, light-weight, reliable and affordable wave buoy.

The Wave Buoy uses a combination of motion sensors and an electronic compass to measure the directional wave field with high accuracy. This yields the directional wave spectrum and all parameters that can be derived from it, such as the 1-dimensional energy-density spectrum and a range of bulk wave parameters (significant wave height, peak wave period, peak wave direction, etc.).

Solar and Battery Version available.

Wave data is sent to the Obscape servers in real-time. The secure Obscape Data Portal enables you to view and download the data or forward them to your own server. Key settings, such as the real-time output interval and the location of the GPS fence, can be adjusted on the fly. The Wave Buoy offers two main modes of communication: the GSM network (4G) and a satellite network (Iridium). While the GSM network offers low-cost data transfer in coastal waters, satellite communication ensures global data coverage. A FIFO queue is able to close connectivity gaps up to 50 days. Additionally, it is possible to work with a hybrid data transfer mode that will attempt to send data over the GSM network first, before switching to satellite communication.

While satellite communication ensures a stable real-time data connection, the use of GPS positioning combined with automated status notifications emails make the system reliable. The GPS position reported by the buoy is continuously compared to the user-specified deployment location. If the distance between the actual and intended position of the buoy exceeds a pre-defined threshold (the watch circle), an email notification is sent to the user. Similar notifications are sent in case of a data gap, low battery level or exceedance of a user-specified wave height threshold. For high-latitude environments with limited solar input, a battery-powered version of the Wave Buoy is available.
