[1] We report here the results from a coupled ocean-atmosphere inversion, in which atmospheric CO2 gradients and transport simulations are combined with observations of ocean interior carbon concentrations and ocean transport simulations to provide a jointly constrained estimate of air-sea and air-land carbon fluxes. While atmospheric data have little impact on regional air-sea flux estimates, ...

[1] The Luzon Strait transport, as an index for the South China Sea throughflow, has attracted much attention recently. In this study the interannual variability of Luzon Strait transport is examined, using the Island Rule and results from ocean data assimilation. Transport variability obtained from these two approaches is consistent with each other. Assessment of contribution from each integra...

In this study, 166 surface sediments and 3 sediment cores from the Bohai Sea (BS), Yellow Sea (YS) and East China Sea (ECS) in China were collected to investigate the spatial and temporal distributions and the transport of PFASs. PFASs concentrations in the surface sediments ranged from below detection limit (<LOD) to 2.78 ng g(-1) with an average value of 0.55 ng g(-1) on a dry weight basis (d...

Two years of TOPEX/POSEIDON altimeter data have successfully been used to study the mesoscale field in the Mediterranean and to investigate the seasonal and year-toyear variability of the sea level and eddy statistics in this basin. The mesoscale field described by TOPEX/POSEIDON revealed a strong, but subbasin dependent, seasonal signal. Year-toyear variations are also evident in terms of both...

The Coastal Aerosol Transport (CAT) model was developed to study the evolution of aerosol particle size distributions and composition in the coastal environment. The model simulates such processes as particle production at the sea surface, mixing of particles through the boundary layer by turbulent diffusion, gravitational settling, and dry deposition. The model is initialized at the shoreline ...

1. Introduction Intermodalism has been increasing both in the world and Turkey due to the demand and supply side developments in transport industry. Turkey has great potential in terms of intermodal transportation owing to its privileged geographical position amid European, Central Asia and Middle Eastern countries. The trend in development patterns in the Mediterrenean, the Black Sea, The CIS ...

In the following document, we summarize the results of studies into the temperatures occurring inside sea containers during transport. Most of the studies we looked at focus on the situation for the wine industry. But we also look at one study concerned with the export of electronic goods. Our goal is to give an overview of the current state of published knowledge on the temperature development...

All of these materials are transported on land, sea or in the air in compliance with regulations which are now universally based on the IAEA Regulations for the Safe Transport of Radioactive Materials Ref. [1]. These regulations are designed to ensure adequate protection of transport workers, the public and the environment against the hazards of external radiation, the spread of radioactive con...

Monomolecular surface films (“sea slicks”) are well known to dampen small-scale waves at the water surface, and thereby to influence transport processes at the air-sea interface. Because of their strong wave-damping capabilities they can often be delineated on synthetic aperture radar (SAR) imagery, but also on satellite imagery acquired in the visible and infrared spectral ranges. Since sea sl...
