Some sea creatures are displaced by the desalination plant, but others actually grow.
Pumping very salty water into the ocean has surprisingly little impact on marine life.
The Derwent River Sea Star was only documented for 25 years before its extinction.

It's quite hard to tell when a sea creature is extinct – there's always hope it will turn up somewhere.
Salt water is fun to swim in – but it also carries the electrical signals vital for life.
We take salt water for granted, and often overlook how important it is for our own lives and in sustaining a healthy planet.
The myth of the empty sea is largely the product of European imperialisms and their map-making.
A new project takes a different look at the role of oceans.
UK bound? The oceanic whitetip.
Forget the scare stories, sharks are good for our oceans.
Waves lap against the shore on the south coast of England and the North coast of France – but the answer to this puzzle is in the wind and the land, not the waves themselves.
Sea turtle eating a plastic bag.
Plastic bags are commonly mistaken for food by sea animals. They require a lot of energy and resources to be made, and have caused floods in some countries.
Predatory fish are among the most vulnerable species to human pressures.
The world has some 500 million square kilometres of ocean. But just 55 million square kilometres remain untouched by intensive human activities such as fishing.
A whale shark moves towards a piece of plastic in the ocean.
If we are truly invested in addressing the issue of marine plastic and offsetting the potential harms, we have to understand which fish eat plastic and which ones don't.

Why do whale sharks come together at just 20 locations around the globe?
Where all the water in the ocean came from is a very good question. Scientists have been wondering about it for a long time.
The Big Bang created a cloud of dust and rocks that included a lot of rocks that were made of ice, like giant snowballs. That's where some of the water came from.

How can marine preserves best protect sea creatures that move in and out of them? Two ocean scientists describe new thinking about designing marine protected areas.
Copepod with eggs (blue). Copepods are typically just a few millimeters long, but are important food sources for small fish.
DNA sequencing is making it possible for scientists to identify thousands of species of zooplankton – drifting animals that are key links in ocean food webs.
Blooms of algae, like this growth in 2015 in Lake St. Clair between Michigan and Ontario, promote the formation of dead zones.

Scientists have mapped a huge dead zone in the Gulf of Oman, without enough oxygen in the water to support life. This Speed Read explains why dead zones form in waters around the world.

Biologists are finding new evidence that these ocean invertebrate grazers don't just ingest whatever they catch. They can actually be picky eaters – and their choices might influence ocean food webs.
A Kemp’s ridley hatchling makes its way to the water on Padre Island, Texas.
During sea turtle nesting season, scientists collect data and assess how turtles are doing. But they know less about how plastic pollution, fishing and warming oceans are affecting turtle numbers.
Sustained ocean warming could greatly reduce catches of fish like these herring photographed off Norway.
Fish are a key food source for millions of people worldwide. But a recent study finds long-term warming over the next 200 years could starve tiny plankton, with impacts that would ripple up food chains.
A plastic bag floats in the ocean in this 2016 photo.
Banning plastic bags in food distribution is complicated and not all municipalities are on board. Are bioplastics a solution?
Boat noise can interfere with the underwater communication of fishes and other marine animals.
The noise from motor boats, sonar and other industrial activity interferes with the underwater chatter of fishes.

With coral reefs in crisis around the world, many organizations are working to restore them by growing and transplanting healthy corals. A new study spotlights techniques that help restored reefs thrive.
