They hang out in the warmer coastal waters of the Atlantic Ocean - think Caribbean, Ascension Island, the Gulf of Guinea.
Apparently, they are eaten in some places, but I can’t say whether or not they taste like chocolate…or cake

Sentinel-6B is a satellite that will give us lots of lovely high-precision data on sea, river, and lake levels.
This data will be super useful for things like:
🛰️ Mapping seafloor features
🛰️ Understanding climate change
🛰️ Help communities and decision makers prepare for flooding

Quieter ship design: New-build and retrofit options – Clear Seas
Click to view glossary In the dark undersea world, sound is essential. Marine life relies on sound for communication, foraging, reproduction, and navigation. However, as human activity in the oceans increases, so does underwater radiated noise. Various industries contribute to ocean noise—offshore energy, construction, military operations, and of course vessel traffic. With growing activity from…

Through the Quiet Vessel Initiative, engineers looked at different ways of making vessels quieter, like
🤫 Designing propellers that push vessels through the water to produce less noise
🤫 Exploring different ways to push vessels through the water that are quieter than propellers

Some of the ways to make vessels quieter involve changing how we do things, like going slower where it is safe to do so. Other ways relate to the design of the vessels and their various components.
This is where engineers come in.

Now we’re not about to stop all of our noisy activity in the ocean, but we can do things to make our activities quieter
A few years ago, the Canadian Government launched the Quiet Vessel Initiative (QVI), which provides funding to projects to make ships, ferries, & other marine vessels quieter

Trouble is, with more boats, more offshore development, and climate change making it easier for sound to travel through the ocean, the ocean is becoming a much noisier place - so much so that marine life may find it harder and harder to go about their business.

In the ocean, sound is super important for all sorts of marine species. Some use it to find food, some find their way around, and some to communicate.
