Of the hundreds of millions of tonnes of plastic waste we produce each year, it’s estimated that around ten million tonnes enters the ocean. Roughly half of the plastics produced are less dense than water, and so they float. But scientists estimate that there are only about 0.3 million tonnes of plastic floating at the ocean surface, so where is the rest of it going?

Consider the journey of a plastic fiber that’s shed from your fleece. A heavy rain washes it into a storm drain or a nearby river. Does the tiny fiber settle there? Or does the river carry it out to the coast where it lingers on the seabed?

Waves are one of the most beautiful and awe-inspiring natural phenomena. Glancing through the ocean, one can see innumerable waves as far as the vision can decipher.

They are in a continual set of motion – rising up, moving forward, splashing amongst themselves, losing their motion and then rising again. They are a treat to watch, and even better to play with.

They are the reason why beach-goers and surfers visit otherwise boring sea beaches. Yes, you heard me right! Imagine a beach, with no waves at all.

Sand and water will be all you’d be left with, which would be…pretty…..boring!

Sea waves are one of the beautiful natural marvels that excite us.

On 9 February, R/V Kronprins Haakon departs on a winter process cruise to the Barents Sea to track and measure important processes taking place in the ocean during wintertime. This cruise is led by UNIS professor Frank Nilsen and part of the Nansen Legacy project – Norway’s biggest research project to date.

Arctic seas have historically been little accessible during winter, but it is during this time of the year that important atmosphere-ocean-processes are taking place. The heat fluxes between the sea and the atmosphere are greatest during winter. These processes are crucial for the Barents Sea for the rest of the year and affects, among others, how

What's that cloud?

 

 

 

Of all weather phenomena, clouds are among the most fascinating. From the silky, high-altitude cirrus to the towering, threatening mass of storm-bearing cumulonimbus, clouds are as varied as the weather itself.


Apart from their beauty and interest, clouds can provide a useful indication of what weather conditions may be on the way. By knowing the ten main cloud classifications, you can get a real sense of what’s happening in the atmosphere.

Cloud formation

Clouds have their origins in the water that covers 70 per cent of the Earth's surface. Millions of tons of water evaporates into the air daily from oceans, lakes and rivers, and by transpiration from trees, crops and other plant life.

As this moist air

"Are hydro-connected floating solar power plants part of the answer to both the integration of more variable renewable energy and the modernization of old renewable assets? Most probably", according to Stanislas Merlet and Bjørn Thorud. (Photo: PowerUp / Shutterstock / NTB)

Floating solar power connected to hydropower might be the future for renewable energy

OPINION: Hydropower plants need an upgrade. And we need to use more renewable energy sources. The solution? Floating solar power connected to existing hydropower plants.
