Tuna returns to the Danish-Swedish sounds

The tuna which has been absent from the Öresund area for many years is starting to reappear according to countings done by Danish and Swedish researchers.

New regulations and better controlling introduced 15 years ago are thus providing results and in combination with an increased amount of the fish species that the tuna feeds on, the tuna stock is now replenishing.

During 2022 the researchers tagged 48 tuna individuals in order to better track their movements for future research.

Eyjafjallajökull and modern communications

The eruption of the Eyjafjallajökull volcano has in a very clear way showed both the weaknesses and strenghts in modern communications. The mass cancellations of flights in large parts of Europe and across the north Atlantic have undoubtedly meant great disturbances in the international transportation sectors both logistically and economically. But the interruptions have also shown the strenghts of other communication networks, both physical ones and telecommunications. Because with todays technology in reality the need for physical travel in order to conduct business is lower than it used to be. In many cases vide and voice conferences can replace the physical meeting, and in the cases it cannot, there are still in many cases alternatives in the form of high-speed trains. In the best case the temporary closure of the European airspace will put a renewed focus on the almost as fast and environmentally sounder ways of inter-European transportation that exist and should be expanded upon.
