Reports from our archives
The youngest German research vessel will primarily operate in the deep sea regions of the Atlantic, the Pacific, and the Indian Ocean. Consequently, she received a.o. two Acoustic Doppler Current Profilers (ADCPs) of the Teledyne RD Instruments OCEAN SURVEYOR series capable of collecting detailed maps of the distribution of water currents along the ship´s path to 1,000m or 700m depth. The phased-array transducers of 38 and 75kHz are installed in the ship´s hull. A “SeaCAT” Thermosalinograph SBE 21 is also working below the waterline. It accurately determines sea surface temperature and conductivity from underway vessels. Data is simultaneously stored in memory and transmitted to a computer serial port, allowing independent data logging and real-time data acquisition. Also on board is a Carousel Water Sampler including a profiling SBE 911 plus CTD with optional sensors of Sea-Bird Electronics. This unit is operated by a deep sea winch and controlled from a deck unit with real-time data display. The vessel can specifically handle heavy equipment like deep-sea AUVs and ROVs. As one example, the autonomous underwater vehicle REMUS 6000 of Hydroid is pictured which was named “ABYSS” by the GEOMAR institute. This, by the way, is the AUV which found the wreck of the AIR FRANCE plane in almost 4,000 m water depth off the coast of Brazil two years after it was lost in 2009. Our photographs were taken during the “Open Ship” of the SONNE at the Ostseekai of Kiel Harbour in November 2014.
When we had moved to our new address Wellseedamm 3, it took some time to get used to the new facilities. But now, on 23 August 2013, we celebrated the formal opening of our new office building with customers, suppliers, and many friends. We counted 139 happy guests who were exchanging pleasant memories while enjoying some good music, food, and drink.
With growing interest in the health of the oceans, and in using the oceans to produce energy, the need to understand and measure human effects on the ocean is rising. Measuring ocean sounds is becoming an important part of meeting new legislation introduced in Europe and North America intended to protect the oceans as development rises. Ocean Sonics makes a new class of product that measures ocean sounds and helps provide greater insight into those sounds, introducing you to a better way to listen in the ocean. ”Smart Hydrophones” add a processor & memory to the digital hydrophone. The data now can have meaning, be processed, streamed or logged in the instrument. The Smart Hydrophone has event detectors that report or log whenever a pre-set of conditions occurs. For details refer to www.oceansonics.com.

Sidney, British Columbia, Canada, have asked us to look after their interests in our territory. – The robust TRIAXYS Wave Measurement Buoys are in permanent use worldwide, and have dramatically reduced the high maintenance cost of known buoys thanks to solar energy. Measurement intervals for wave height and direction, and other parameters, can be programmed. Data is recorded on internal data logger, processed, and after quality control transmitted via radio, cellular or satellite telemetry. The TRIAXYS sensor unit is comprised of three (3) accelerometers, three (3) rate gyros, a fluxgate compass, the proprietary TRIAXYS Processor and a sea surface temperature sensor. The resolution of the buoy motion in three dimensions (six degrees of freedom), provides more accurate measurements. Ten solar panels and four batteries warrant yearlong uninterrupted operation.
At the beginning of 2008, three German institutions successfully started operating new towed BENTHOS Sonar Systems combining wide swath bathymetry, side-scan sonar, and sub-bottom technology. Supplemented by patented sonar imaging, the systems deliver a 3-dimensional look at the seafloor with unprecedented resolution. Whereas the research center FWG chose the Model 1625, the test center WTD 71, and the IfG of the University Kiel both use the Model C3D. All sensors are housed in the same tow body so that they look identical from the outside. Please contact us and/or the website of the manufacturer for technical details.
The German Research Foundation (DFG) has placed the order for an Autonomous 6000m Underwater Vehicle (AUV) with HYDROID, the U.S. manufacturer represented by us. The System was delivered to the Leibniz-Institute for Marine Sciences IFM-GEOMAR, Kiel, in October 2008. The contract worth approx. USD 3.2 Million is the largest single order received in our 30 year company history. The underwater vehicle REMUS 6000 is 3,84 m (12.6 ft) long, has a diameter of 0.71 m (28 in), and weighs 862 kg (1900 lbs) in air. Subject to speed and sensor configuration, the autonomous mission duration can be up to 22 hours. Launch and recovery from a research vessel is accomplished with the aid of a special hydraulic frame (LARS). The instrument package comprises a.o. swath bathymetry, side-scan sonar, sediment profiler, ADCP, CTD, optical sensors, photo cameras, and navigation equipment. The system is stored and transported in two 20 ft containers allowing deployment from various research vessels.

Supplemental to the original Color and B/W Video Cameras of the ROV, we supplied an IMAGENEX Scanning Sonar, an RDI ADCP, a SEA-BIRD CTD, an AANDERAA Oxygen Sensor, and an ORE Tracking System for acoustic positioning, which were integrated in a Survey Skid. Our service company Oktopus added a special, fast Photo Camera System allowing high-resolution biological takes. In view of the many instruments to be connected, fiber-optic telemetry was chosen. The first field deployment in the North Sea was a great success.
reports about the deployment of a McLane Moored Profiler MMP in the tropical Atlantic approx. 5°N, 23°W. The sensor platform is the core element of a 4210m deep mooring carrying among others an RDI Long Ranger ADCP and two Sea-Bird MicroCats for reference. The motor driven MMP Profiler is crawling slowly up and down the mooring wire measuring various parameters on its way between 100m and 1000m water depth.
After successful trials of the system in the bay of Kiel in spring of 2004, we are delivering the first combined side-scan sonar and bathymetry system model C3D to the German Navy Research Center (FWG) in 2005. The modular design is allowing them to employ this new, patented high-resolution technique on AUVs or towed from research vessels. The topside processor is connected via Ethernet, and there are additional interfaces for optional external sensors.
In May 2005 we delivered a 6,000m Digital Photo Camera System to the Leibniz-Institute of Marine Sciences in Kiel. The Camera System, which was designed by Ocean Imaging Systems, has a resolution of 6.1 Megapixel and is completely built from Titanium. It will be used for the first time in June of 2005 during Alkor Cruise 259 on a lander in the North Sea.
stands for “Assistance System for Safe Shiphandling”. It is a development of the University Rostock, Institute of Automation Technologies, funded by the German Ministry for Research and Technology (BMBF), to monitor environmental parameters like ocean currents and wind influencing the navigation of large vessels in narrow sea corridors and harbor approaches. Target of the development is the avoidance of collisions. The first system was installed at the ferry harbor of Puttgarden in the Baltic Sea. The ocean currents are constantly measured by an RDI Horizontal ADCP 300kHz with a range of approx. 300m. The instrument is mounted on a jetty wall at the entrance of the ferry harbor. During the trial phase, additional measurements were taken by an RDI Vertical ADCP on the remote controlled catamaran MESSIN® which can cover large areas in great detail. The measured current data is transmitted to the vessels by the AIS transponder system and integrated into the ECDIS system on the bridge of the ferry.
