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: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
