Improved marine debris detection in satellite imagery with automatic refinement of coarse hand annotations

Devis Tuia, Marc Conrad Russwurm, Elif Dilge Gül

Plastic litter is a major environmental hazard that endangers human, animal, and plant health on the planet. A substantial portion of plastic pollutants is washed from rivers and beaches into the oceans and aggregates at the surface as marine debris before ...

Insights into the Horizontal and Vertical Profiles of Microplastics in a River Emptying into the Sea Affected by Intensive Anthropogenic Activities in Northern China

Florian Frédéric Vincent Breider, Yang Liu, Wenxin Liu

Studies focused only on surface water may underestimate microplastic abundance in aquatic environments. This was the first survey to investigate the vertical (surface, intermediate, and bottom waters) distribution and composition of microplastics (MPs) in ...

Microbial-induced carbonate precipitation applicability with the methane hydrate-bearing layer microbe

Alexandra Clarà Saracho

Production of methane gas from the methane-hydrate-bearing layer below the deep-ocean floor is expected to be crucial in the future of energy resources worldwide. During the methane gas-production phase from the methane hydrate with the depressurisation me ...

Effects of Anthropogenic Discharge and Hydraulic Deposition on the Distribution and Accumulation of Microplastics in Surface Sediments of a Typical Seagoing River: The Haihe River

Florian Frédéric Vincent Breider, Yang Liu, Wenxin Liu

Microplastics pollution in river systems has generated great concern; however, few studies have focused on the contributions of multiple influencing factors to microplastics in river systems. In the current study, we utilized data on microplastics in surfa ...

On the Metal Contents of Ocean Floor Nodules, Crusts and Massive Sulphides and a Preliminary Assessment of the Extractable Amounts

The metal contents of ocean floor nodules, crusts and massive sulphides was estimated and an assessment of their commercial extractability were conducted. The metals considered were iron, manganese, copper, nickel, cobalt, molybdenum, platinum, gold and si ...

Sediment mass movement of a particle-laden turbidity current based on ultrasound velocity profiling and the distribution of sediment concentration

Giovanni De Cesare, Shun Nomura, Jumpei Hitomi

Particle-laden flows or turbidity currents along the seafloor are important to the formation and erosion of submarine topography. To understand the mass-transport process, flume tests were carried out with a continuous supply of quartz-laden suspension. Th ...

Bar dynamics and sediment transport pulses in gravel-bed channels.

Christophe Ancey, Blaise Etienne Marceau Dhont

Mountain rivers exhibit sediment transport rate fluctuations that often cover more than two orders of magnitude. Bedform migration is often cited as the key process that causes giant fluctuations in the sediment transport rate. To quantify the effect of be ...

Sediment balance of a cascade of alpine reservoirs based on multi-decadal data records

Anton Schleiss, Pedro Filipe De Almeida Manso, Sebastián Guillén Ludeña

Reservoir sedimentation is a major concern in the operational management of dams and appurtenant structures. The increasing volume of sediments deposited in reservoirs leads to a loss of water storage, undermining the purpose itself of the dam for human us ...
