Around one-third of fish stocks worldwide are overfished, while 20 percent of all seafood is obtained through illegal, unreported, and unregulated fishing. Most such fishing, known as IUU, occurs on the high seas, where the governance of marine areas is tricky and their protection is virtually non-existent. IUU fishing vessels pursuing the largest profits often ...

“We need to use an external frame of reference when making measurements of the Earth’s position, tilt and speed of rotation, and that these supermassive black holes are our best indicator as they don’t really move.” These measurements, called Earth Orientation Parameters, are used by Global Navigation Satellite System (GNSS) satellites to help geodesists understand ...
