During World War Two scientist improved sonar technology to such a degree that it could indeed sense and inform you of what way or direction the object is moving,

Active sonar sends out waves at the speed of sound and when they reflect back to the ship an image is drawn much more like how a bat uses eco-location but it’s underwater

The other type of sonar is passive sonar which as the name describes is passive and doesn’t send any waves just listens and identifies the waves]]> 2022-03-30 13:50:25 UTC https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121526895 https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121528980 2022-03-30 13:51:20 UTC https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121528980 https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121530460 6 Illegal Fishing Methods and Destructive Practices

The early 1990s fishery crisis was caused by a mix of greed, ineptitude, and government support for both. Unfortunately, it's only one of many examples of how humans often make issues worse by attempting to solve them. "It would be some consolation for the feebleness of our selves and our efforts if all things perished as slowly as they came into life," the philosopher Lucius Anneus Seneca said nearly 2000 years ago. "But as it is, increases are of gradual growth, but the route to ruin is swift."]]> 2022-03-30 13:52:22 UTC https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121531329 https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121532488 A longline is a single, very long fishing line that is dragged behind a boat. It has thousands of smaller branchlines attached, each of which has a baited hook that’s used to lure and catch the target fish. Longlines can be used near the ocean’s surface or the seafloor, depending on the fish being targeted, and can stretch for up to 60 miles.]]> 2022-03-30 13:52:54 UTC https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121532488 https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121532830 2022-03-30 13:53:04 UTC https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121532830 https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121533193 Cabin display of a fish finder sonar]]> 2022-03-30 13:53:13 UTC https://padlet.com/mpross4/q2n9dsq2cwdnepcl/wish/2121533193
