The 1539 Carta marina by Olaus Magnus (original size 1.7 x 1.25 m). It is on
display at Carolina Rediviva, the library of the University of Uppsala, Uppsala, Sweden.
The ornate map, seemingly crude by today’s standards, depicts sea monsters off the coast of Scotland, sinking galleons, sea snakes, and wolves urinating against trees.
When oceanographers from Plymouth Marine Laboratory and the University of Rhode Island compared a large group of swirls, shown on the chart off the east coast of Iceland, with thermal images from an Earth observation satellite they found the swirls corresponded almost perfectly with the Iceland-Faroes Front - where the Gulf Stream meets cold waters coming down from the arctic.
The cartographer, Olaus Magnus, an exiled Swedish priest living in Italy, had a dislike of blank canvases and covered every available space with ink. But Professor Tom Rossby, from the University of Rhode Island, believes not every elaborate quill stroke was artistic licence.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
