Marine microplastics generated by wear and tear of bottom trawls and demersal seines during their service life is a growing environmental concern that requires immediate attention. In Norway, these fishing gears account for more than 70 % of the landings of demersal fish species, but they are also...

A common task in oceanography is to model the vertical movement of particles such as microplastics, nanoparticles, mineral particles, gas bubbles, oil droplets, fish eggs, plankton, or algae. In some cases, the distribution of the vertical rise or settling velocities of the particles in question can...

Microplastics (MPs) and nanoplastics (NPs) are ubiquitous in the marine environments due to the wide use and mismanagement of plastics. However, the effect of MPs/NPs on the nutrition quality of economic species is poorly understood, and their underlying mechanisms remained unclear. We therefore...

From 2013 to 2022, the available volumes, degree of utilization, as well as the application of different fractions of marine rest raw materials, like heads and skins, originating from the Norwegian seafood industry have been studied and mapped. The majority of the rest raw materials were still used...

The negotiations for a new legal instrument for Biodiversity Beyond National Jurisdiction (BBNJ) concluded in March 2023 with a successful, and somewhat surprising, finalization of a treaty. The BBNJ treaty is a remarkable achievement. But these outcomes – the circumstances of finalization and the...

Using ammonia as fuel in retrofitted large marine vessels or heavy-duty vehicles has the potential to reduce CO₂ emissions. However, ammonia is hard to burn in an internal combustion engine (ICE) due to its poor combustion properties, i.e. having high autoignition temperatures and low flame speeds...

Introduction: The common periwinkle Littorina littorea is a delicacy in southern Europe. Enabling aquaculture production would be measure to avoid future over-harvesting and ensure a constant market supply. Methods: However, knowledge gaps in reproductive biology needs to be filled to allow setting...

With the gradual improvement of environmental emission requirements in China, the graphite industry is facing environmental pressure from advanced treatment. This article first conducted a study on the current status of advanced treatment technology for fluorinated wastewater. Subsequently, a single...
