WHO STILL REMEMBERS?

In 1980, we brought the very first multibeam sonar system to Germany and initiated a technical revolution. Large area, precise contour maps of the ocean bottom could be generated in short time and formed the basis for well-aimed work from now on.

The Kieler Nachrichten reported about this sensational event, and SEA BEAM became a generic term with marine scientists.

ARRAY FUNCTION OF OCEAN SONICS HYDROPHONES

The manufacturer remarks:  Creating digital hydrophone arrays is now simple. Connect two or more icListen Smart Hydrophones together and they self-synchronize, operating as one. Whether using the internal hydrophone memory, or logging multi-channel data externally, you record multichannel array data. The Ocean Sonics approach offers a wide range of geometries, including vertical, horizontal, very small geometrical arrays, or spread out over many kilometers.

RV “SONNE” EQUIPPED WITH MOST MODERN TECHNOLOGY

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.

AXYS TECHNOLOGIES, INC.

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.

ASFOSS

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.

THE INSTITUTE FOR MARINE RESEARCH KIEL (IfM),

reports about the successful operation of a 75 kHz Ocean Surveyor “phased array” Doppler Current Meter System of RD Instruments, San Diego, California, USA. In this vessel mounted system the four acoustic beams are formed by a single flat transducer unit. The small dimensions facilitate hull mounting considerably. The diameter of the 75 kHz transducer is 432 mm, the height only 85 mm. Two switchable methods of signal processing allow the operation of the ADCP either in NarrowBand mode for maximum range or in BroadBand mode for highest possible resolution. After successful trials of the new concept on the German research vessel SONNE in the Atlantic off Brazil in November 2000 the first system of this kind was installed on the German Research Vessel METEOR in 2001. The moving vessel now measures current profiles over the whole water column to 600 m depth. The larger 38 kHz Ocean Surveyor achieves ranges of more than 1000 m. UPDATE: The newbuilding of the Research Vessel SONNE will also receive ADCP Doppler Current Meters. In July 2012, the Neptun Shipyard Rostock placed an order with us for two each RDI Ocean Surveyors, 75 and 38 kHz, for installation in 2013.
