The assessment of planktonic organisms is a prevailing task in marine ecology and oceanography as planktonic organisms form the principal food source for consumers at higher trophic levels. Reliable estimates on the production at the lowermost trophic levels are thus an integral part for the managem...

Limited experimental and field data are available describing oil droplet formation from subsea releases at high pressure. There are also analytical challenges quantifying oil droplets over a wide size and concentrations range at high pressure. This study quantified oil droplets released from an orif...

Abstract—Plastics have permeated almost every aspect of modern day life with its wide applicability. The tragic consequence is millions of pieces of plastic polluting and harming sea life every day. The road towards a clean sea contains several legs and requires mapping of the ocean water column to ...

When an oil field ages and the pressure in the reservoir decreases, or for oil fields with heavy oil, there may be a need for enhanced oil recovery (EOR) technologies. Polymer injection is a water-based EOR method where the viscosity of the water injected for pressure support is increased by mixing ...

The degree to which droplet shedding (tip-streaming) can modify the size of rising oil droplets has been a topic of growing interest in relation to subsea dispersant injection. We present an experimental and numerical approach predicting oil droplet shedding, covering a wide range of viscosities and...

SINTEF ble kontaktet av NOFO 15.05.2019 angående observert overflateolje av tankskipet "Eagle Bergen" som på det tidspunktet gjennomførte lasting fra lastesystemet ca. 2 km fra Statfjord A plattformen. SINTEF bistod i perioden 15-16. mai med prøvetaking av oljeprøv...

The impact of the physical environment and phytoplankton size on particle types (zooplankton, biogenic matter or phytodetritus) in the water column is poorly understood. Here, we investigate how hydrography (e.g. water column stratification) impacts phytoplankton size and photophysiology across a pr...

Both oil droplets and gas bubbles have simultaneously been quantified in laboratory experiments that simulate deep-water subsea releases of both live oil (saturated with gas) and additional natural gas under high pressure. These data have been used to calculate particle size distributions (50–5000 μ...
