A circulation model is coupled to a Lagrangian particle-tracking model to simulate the transport floating litter particles in the Aegean Sea, Greece (Eastern Mediterranean). Considering different source regions and release dates, simulations were carried out to explore the fate and distribution of floating litter over 1990–2009, taking into account the seasonal and interannual variability of su...

The paper presents the results of the joint project carried out in Germany in order to assess the consequences in the marine environment from the dumping of nuclear wastes in the Kara and Barents Seas. The project consisted of experimental work on measurements of radionuclides in samples from the Arctic marine environment and numerical modelling of the potential pathways and dispersion of conta...

[1] A one-dimensional, thermodynamic, and radiative model of a melt pond on sea ice is presented that explicitly treats the melt pond as an extra phase. A two-stream radiation model, which allows albedo to be determined from bulk optical properties, and a parameterization of the summertime evolution of optical properties, is used. Heat transport within the sea ice is described using an equation...

Climate variability influences seabird population dynamics in several ways including access to prey near colonies during the critical chick-rearing period. This study addresses breeding success in a Barents Sea colony of common guillemots Uria aalge where trophic conditions vary according to changes in the northward transport of warm Atlantic Water. A drift model was used to simulate interannua...

In todays industries requirements are put upon that the different actors integrate their performance for the purpose of the transportation system as a whole. Door-to-door processes, seamless integration, and multi-modal integration are expressions for such movement where the requirements of the beneficiaries are put at the core. Digitalization could enable such movement. For midand long-range t...

Climate change can strongly influence coral reef ecosystems, affecting species composition, growth rates, and reef morphology, potentially leading to altered wave energy dissipation across reefs. Sea level rise can also alter wave dissipation, which may lead to shifts in alongshore sediment transport gradients, thereby altering erosion and accretion patterns on tropical coastlines. Delft3D was ...

A global three-dimensional chemical transport model (CTM) is used to model the yearly cycle of sea salt.Sea salt particles are produced by wind acting on the sea surface, and they are removed by wet and dry deposition.In this study, forecast meteorological data are taken from the ECMWF. The modeled concentrations are comparedto measured concentrations at sea level, and both absolute...

Much attention has been given in recent years to observations and models that show that variations in the transport of the Atlantic Meridional Overturning Circulation (AMOC) and in the Gulf Stream (GS) can contribute to interannual, decadal, and multi-decadal variations in coastal sea level (CSL) along the US East Coast. However, less is known about the impact of short-term (time scales of days...

Mesoscale eddies, which contribute to long-distance water mass transport and biogeochemical budget in the upper ocean, have recently been taken into assessment of the deep-sea hydrodynamic variability. However, how such eddies influence sediment movement in the deepwater environment has not been explored. Here for the first time we observed deep-sea sediment transport processes driven by mesosc...

[1] We apply ‘‘residual mean’’ theory of tracer transport, in which eddy transfer plays a fundamental role, to develop scalings and idealized numerical models of the Southern Ocean uptake of transient tracers. The streamline-averaged numerical model, which represents transport in the meridional plane, captures the observed distributions of CFC-11, bomb-DC, and anthropogenic CO2. The model repro...
