Air-sea interaction tower built off Marthas vineyard
ASIT with platform in place
In the deep waters two miles south of Edgartown on Marthas Vineyard, not far from where, two centuries ago, the likes of Captain Ahab and a thousand others kept their watch for the great white and his kin, we are now searching to understand another potential beast in those parts: the ocean and the weather.
But this is no allegory. Hoping to avoid any recurrence in these sometimes turbulent waters of the horrendous storms so intensely portrayed in Moby Dick as well as The Perfect Storm, the Office of Naval Research has built a tower bristling from top to bottom with sensors. The Air-Sea Interaction Tower will continually measure atmospheric and ocean conditions such as air temperature, humidity, solar radiation and carbon dioxide, as well as water temperature, salinity or salt content, wave height and direction, water circulation, current speed and direction, and sediment transport. It will directly measure momentum, heat, and mass exchange between the atmosphere and ocean. Anchored 50 feet down into the ocean floor, the tower extends 76 feet into the marine atmosphere. It will be maintained and operated by scientists at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts and will be connected by undersea cables to WHOIs Marthas Vineyard Coastal Observatory (MVCO).

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
