Introduction Seabed Surveying using ROVs/AUVs

We will cover the installation of vessel and ROV survey equipment and explain the importance of offsets, calibrations and installation checks. We will discuss the relevance of the installation positions on both vessel and ROV in providing the best quality data without interference and explain the different types of surveys and the equipment needed to ensure accurate time stamping. Should you be interested, send us a message and we will forward more information. (read more)

NATO Surveying Borders of Cape Verdean Wildlife

NATO surveying borders of Cape Verdean Wildlife sanctuary prior to Exercise Steadfast Jaguar 2006. Prior to the NATO Response Force exercising off the Cape Verde Islands in June this year German Research Vessel FGS Planet will conduct a hydrographical survey of the borders of a Cape Verdean conservation area in order to ensure maritime vessels keep clear of a 200 metre depth contour. FGS Planet has surveyed the 200m contour line around the islands Brago, Razo and Santo Lucia from 07-14 April in support of NATO Exercise Steadfast Jaguar. The collected data will be handed over to the Cape Verdean... (read more)

Economic Surveying in Middle-East and Siberia

No Limit Ships has received an order for a No Limit Professional from MRTS, Russia, for surveys in and around the Caspian Sea. The vessel is to be delivered in May 2012. In the end of last year, deliveries have been taking place of several vessels with jobs in the Middle-East. The No Limit Professional vessels facilitate surveying with a multi-beam echosounder at a high speed, which is economically attractive as a big area can be mapped in a short time. In the summer of 2010, a No Limit 1640 Professional has been transported to Qatar to survey in the... (read more)

Surveying Japanese Inland and Coastal Waters

Technical Records Set for Lidar Penetration
In March 2015, Leica Geosystems conducted a series of demonstration surveys in Japan with the HawkEye III Airborne Topographic Bathymetric Lidar system. This demonstration was designed to prove the depth performance and general capabilities of the HawkEye III system in Japanese waters. It ambitiously targeted 13 geographically separated areas ranging from land-locked rivers, coastal estuaries and coastal strips to offshore islands and coral reefs. The HawkEye III successfully demonstrated its capabilities, collecting seamless datasets in diverse coastal and river environments as well as setting new records for depth penetration for both the HawkEye III deep sensor and the Chiroptera II shallow...

CEESCOPE-USV Echosounder for Remote Hydrographic Surveying

CEE HydroSystems has announced the release of a singlebeam echosounder survey system, designed specifically for the growing number of shallow-water unmanned surface vehicle (USV) survey applications using both commercially-available and custom-manufactured remotely operated boats. The CEESCOPE-USV is an echosounder, GNSS and broadband radio telemetry package that can be installed on practically any remotely operated boat. As an entirely self-contained module requiring no interface with the USV, challenges of instrument data integration on the vehicle are minimised or eliminated. Rigorous data handling eliminates latency concerns resulting from radio transmission to the shore, and the CEESCOPE-USV brings a clear separation between the... (read more)

Reconnaissance Surveying using Satellite-derived Bathymetry

Bechevin Bay, AK, Pilot for Survey Planning Approach
False Pass, AK, USA, is the eastern-most passage through the Aleutian Islands between the Bering Sea and the Pacific Ocean and provides a passage for small to mid-size vessels. The passage is considered an alternative route to Unimak Pass, AK for vessels from mainland Alaska and is estimated to be shorter by 160 to 240km. False Pass is closed every winter due to sea-ice cover that freezes the inlet system around October-November and melts only towards the spring (around March). As a result, the soft sediment of the seafloor contains mud and sand that may change the path of the... (read more)
