Radar Hydrography

Projects

The department of Radar Hydrograhy is involved in several national and international projects. These projects a related to the development as well as application of radar remote sensing methods for getting a better understanding of surface and near surface processes.

COSYNA - HF-Radars Monitoring of the German Bight

Within the COSYNA project the department of Radar Hydrography operates three HF-radar systems along the German coast (Wangerooge, Buesum and Sylt). The radars are operated continuously and deliver a surface current field of the German Bight every 20 minutes. In addition the data are used to develop methodologies for ship detection tracking and fusion, which result in maps of ship tracks that are updated every 33 s. The later activity is performed in collaboration with the [url=http://www.cmre.nato.int/]Center for Maritime Research and Experimentation (CMRE)[/url, La Spezia, Italy.

Marineradarbunkerhilsylt Horstmann

Marine radar retrieved bathymetry in front of Bunkerhil, Sylt.

In addition the department operates 2 of their coherent marine radar systems at the island of Sylt and at the research platform Fino-3, located in the German Bight. The Sylt radar is utilized for testing the monitoring capability of radar retrieved bathymetry and the Fino-3 radar for retrieving currents and waves on an operational basis with HZGs radar tool ROWMS.

Fino-3 - Investigation of the Influence of Wind Farms on Sea State

HZG's coheren X-band marine radar mounted on the research platform Fino-3.

Within the Fino-3 Project the department is investigating the influence of the offshore wind parks on the climate of the surface waves. Therefore we are utilizing our X-band marine radar systems as well as different in situ devices available on the offshore platform Fino-3 as well as temporary moored equipment during the Heincke cruise (May, 2015). The Fino-3 project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWi).

WaveDis - Ocean Surface Wave Dissipation

Experimental setup at Moeskendeel and Bunkerhill on the island of Sylt, Germany.

The main objectives within this project is to develop methods for measuring individual parameters of ocean surface waves to get a better understanding of surface wave dissipation due to wave breaking, wave current interaction as well as shoaling. The main study areas are at the research platform Fino-3 as well as the west coast of the island Sylt.

Lindesnes - Coherent Marine Radars for Measuring Sea State

HZG's coherent X-band marine radar system is operating since 17. January 2015 at the lighthouse of Lindesnes, Norway.

In this project the department is testing and improving their algorithms for wave retrieval using coherent marine radars. Therefore, a coherent marine radar is beeing operated at the lighthouse of Lindesnes, Norway since January 2015. The data are utilized to measure the spectral wave parameters (e.g. peak period, peak wave direction and significant wave height) as well as individual wave paraneters (e.g. wave height). These parameters will be compared to the meaurements of two bottom mounted Acoustic Wave and Current Profilers (AWACs). This project is funded by the Norwegian Reserach Council within a colaboration between NORTEK and the University of Oslo, Norway.

JericoNEXT - Improvement of HF-Radar Current and Wave Products

Current field resulting from the HF-radar network of the German Bight.

Within the HF-radar work packages of JericoNEXT the main objectives are:

  • improvement of HF-radar current and wave retrieval algorithms with respect to strong spatial and temporal varying currents.
  • development of an improved quality control resulting in maps with additional error flags with respect to the accuracy of surface currents.

JericoNEXT is funded by the European commission within the framework of Horizon 2020. For more information refer to JericoNEXT
