A robotic microplankton sniffer dog

The microscopic, free-floating algae called phytoplankton — and the tiny zooplankton that eat them — are notoriously difficult to count. Researchers need to know how a warming climate will affect them both. A new kind of smart, lightweight autonomous underwater vehicle (LAUV) can help.

Shedding light — on the polar night

The polar night is dark — if you’re a person. But not if you’re a krill or a seabird or a fish. In the first episode of NTNU’s new English-language podcast, 63 Degrees North, learn how researchers discovered that there’s more than enough light in the polar night for the tiny creatures who live there.

Smart site selection can make hydropower greener

Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.

Reveals hungry salmon with sound waves

The feed cost represents about 50 percent of the costs of farming salmon. But how do we know if the salmon is hungry or still full? Researchers have rethought to find answers. The result is less wastage and pollution – and enough food for the salmon.

Meet the aquaculture industry’s new maintenance bot

This ROV can fully operate on its own, and follow along with fish’s behaviour and health with its Argus eyes – all while keeping a safe distance. It even inspects the technical standard of the enclosure while it’s at it. Say hi to Mr. CageReporter.

Teaching robots to cooperate underwater

The launch of a new research centre for robotics will provide increased knowledge about the sea with the help of underwater drones and robots. This could impact Norway’s international role as a major power at sea, says centre director.

Why aren’t sea trout thriving anymore?

Sea trout numbers are declining in Norway and scientists don’t know why. They have studied the trout in two rivers in northern Norway’s Nordland county. Soon, sea trout along the entire Norwegian coast will be investigated.
