working on it the better,” says Fossen, adding that the costs of AUVs are prohibitive, so researchers build their own payloads. AMOS researchers have just developed their own, “low-cost” spectral camera: “What’s hot about this research is that hyperspectral cameras (using chemical calculations) can measure all the colors of our (electromagnetic) spectrum, so it sees what you can’t see with your eyes. It can see the kind of metal a plate of metal is or it can look at a coral and see color that you can’t see with your eyes.”Martin Ludvigsen, an NTNU professor

OSIL Unveils Microplastics Sampler

Oceanic microplastic pollution is a growing concern across the globe as new and existing marine litter continues to degrade and fragment through physical and chemical processes.Global environmental monitoring experts Ocean Scientific International Ltd (OSIL) has developed a new Microplastics Sampler for the collection of water samples for the analysis of plastic particles smaller than 5 mm including fragments, films, pellets/nurdles, granules/beads, filaments and foams.The unique device is a large volume water sampler that allows researchers to collect and characterize suspended and sinking particles

The dye, just like oil, can float in the top 13 feet of the water column, but biodegrades in sunlight in a matter of hours.“This specific water test was intended to check

Hunting Hydrocarbons

Subsea gliders are taking to the oceans to hunt for an ever wider array of anthropomorphic and chemical signatures to an ever greater accuracy.Ocean glider systems are maturing. Since emerging in the 2000s, they’ve opened up new possibilities for ocean observation and monitoring. But, these possibilities are continuing to expand, including to gas seep surveys, leak detection, mammal monitoring and oil spill monitoring, for the offshore oil and gas industry.The primary attraction of ocean gliders is their ability to stay at sea for months, monitoring wide areas in remote locations down to significa
