Commissioning of the new AWI research ship MYA II

12.08.2013
On 13 August 2013 the research ship MYA II will be handed over to science at a ceremony in List on Sylt.

Prof. Dr. Waltraud Wende, the Schleswig-Holstein Minister for Education and Research, is going to be present at the event, as well as representatives of the Federal Ministry for Education and Research.

One highlight will be the awarding of the “Blue Angel” eco label for the environmentally friendly ship design of the MYA II. The public will then be invited to get to know the ship in List harbour, and talk to scientists during the open day at the neighbouring Alfred Wegener Institute’s Wadden Sea Station Sylt.

“Whilst this is our smallest research vessel, it is extremely modern and ideally equipped for coastal research”, said Prof. Dr. Karin Lochte, Director of the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) during the launch of the MYA II last month in the Fassmer shipyard. She is impressed by the modern technology on board which is reminiscent of the equipment on large research vessels.

The ship has a network and data logging system, which continually stores the measurements from various sensors centrally. Fixed installations include a navigation system for precise position location, a sonar system for mapping the seabed, a multibeam echo sounder to estimate the biomass of fish and an ADCP for measuring the current. In addition the stern of the MYA II has a crane boom, the so-called A-frame. Using this the two-man crew and up to twelve scientists are able to lift heavy equipment weighing up to a tonne from the working deck into the water, such as the box corer used to obtain sediment samples.

These scientific measurement and sampling devices are moved using trawl lines or research winches. In addition to recording data, a so-called single core cable enables sampling devices to be opened or closed by computer if the sensors indicate conditions pointing to exciting small algae or animals.

Unlike its predecessor, the research catamaran MYA, the MYA II is a single hull ship, achieving a speed of up to ten knots. “This means we can extend our examination radius around Sylt and up to Helgoland”, says geologist Dr. Christian Hass from the Wadden Sea Station Sylt. The AWI scientist will be one of the principal users, taking samples from the seabed with corers.

He combines grain size analyses of sand and silt with bathymetric and other hydroacoustic measurement data, and on the basis of this compiles comprehensive maps. “These help us understand where various kinds of sediment are deposited, how the seabed is structured and which plants and animals it provides suitable habitats for”, Hass explains. “When repeated regularly these measurements enable us to recognise changes and to correlate influential factors such as climate change or anthropogenic influence”, the geologist adds.

Together with biologists at the Wadden Sea Station, Hass uses an underwater video system on board. On the one hand this makes it possible to directly control whether the seabed actually looks the way it is interpreted on the basis of measured data. On the other hand it also shows what is living beneath the surface of the water. The interaction of flora and fauna in the food web is one of the biological key issues examined at the AWI Wadden Sea Station. Scientists have long gone beyond a simple description of “who is eating whom?” They use computer models to calculate material flows between the various levels of the food web under diverse environmental conditions.

They start with the productivity of phytoplankton, which produce energy from sunlight, moving on to crustaceans and fish and then to seals and to humans as end consumers. “The new multibeam echo sounder will, for example, enable us to estimate fish biomass without net catches. Previously we had to catch large numbers of fish and determine their length individually using a measuring board”, the Sylt coastal researcher PD Dr. Harald Asmus says to explain the advantages of the new measuring technology.

“We are now able to investigate the demands of individual species and their interaction without a need for intervention in the ecosystem. This provides us with the basis for a responsible use of the Wadden Sea, which is a UNESCO world heritage site,” the biologist says.

Young scientists will also be able to use the new coastal research tool. Students from national and international universities are regular guests on Sylt. As with students at graduate schools, on internships and at summer schools, on board they learn about using modern oceanographic equipment. The motorised dinghy brings those interested in processes in flat water and on the mud flats right up to tidal inlets.

“We placed great value on environmentally friendly technology when building the MYA II in order to minimise disturbance to the Wadden Sea caused by research activities,” says AWI Director Prof. Dr. Karin Lochte. The new ship, which cost 4.5 million euros to build, has a particulate filter as well as a waste gas purification system, which removes nitrogen oxide (NOx) from engine exhaust fumes.

As a result, the NOx emissions of the MYA II are around 85 % below the current limit. Moreover an environmentally friendly ship coating was used and an impressed current system was installed to prevent corrosion on the hull as a substitute for toxic zinc anodes. Neither wastewater nor oily bilge water from the engine room get into the sea, but are disposed of in port. Dr. Ralf-Rainer Braun, member of the eco label jury is pleased about the award: “The MYA II demonstrates that more environmental protection is possible in shipbuilding. We hope that the Blue Angel on the MYA II will serve as a positive example to other research vessels.”

The eco label will be revealed during a celebration on 13 August 2013 when the MYA II is handed over to science. Following the commissioning of the ship, it will open its doors from 4.30 to 7 pm in List harbour on Sylt to give interested guests an opportunity to look around the new research vessel. Employees invite people to the open day at the nearby Wadden Sea Station (Hafenstraße 43) from 4.30 to 9 pm, and are looking forward to talking to guests about their current research work.

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Im Focus: Repairing defects in fiber-reinforced plastics more efficiently

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.

Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
