[1] It is often assumed that ventilation of the atmospheric boundary layer is weak in the absence of fronts, but is this always true? In this paper we investigate the processes responsible for ventilation of the atmospheric boundary layer during a nonfrontal day that occurred on 9 May 2005 using the UK Met Office Unified Model. Pollution sources are represented by the constant emission of a pas...

forty seven sediment cores recovered from the south china sea coasts along the east coast of peninsular malaysia were analysed for as, cd, cr, cu, hg, ni, pb and zn using instrumental neutron activation analysis. the results indicate a homogeneous distribution except for as and pb in all stations. assessment of heavy metal pollution in marine sediments requires knowledge of pre-anthropogenic me...

[1] We use the GEOS-Chem chemical transport model and its adjoint to quantify source contributions to ozone pollution at two adjacent sites on the U.S. west coast in spring 2006: Mt. Bachelor Observatory (MBO) at 2.7 km altitude and Trinidad Head (TH) at sea level. The adjoint computes the sensitivity of ozone concentrations at the receptor sites to ozone production rates at 2 2.5 resolution ov...

of the Dalmatian coast type, formed primarily from karst limestone, Eastern Adriatic coast shows great diversity of habitats. This diversity is also influenced by the position of the Adriatic Basin, stretching from northwest to southeast, climatic differences along its length, and the direction of sea currents. Habitats in the submerged karst characteristic for the Croatian side of the Adriatic...

Patterns of microbial distribution represent the integrated effects of historical and biological processes and are thus a central issue in ecology. However, there is still active debate on whether dispersal limitation contributes to microbial diversification in strongly connected systems. In this study, sediment samples were collected along a transect representing a variety of seawater pollutio...

tions in porewater and seawater labile metal concentrations associated with copper mine tailings disposal into the coastal waters of the Atacama region of northern Chile. Marine Pollution Bulletin 44, 956–976. Lionetto, M.G., Caricato, R., Giordano, M.E., Pascariello, M.F., Marinosci, L., Schettino, T., 2003.

European project: CONTRABAND Programme: Short presentation of the speaker: Mr. Dirk Kutscher received his diploma in computer science in 1997 for his thesis “Development of an open, distributed and configurable Sensing Architecture for the airborne Detection of Sea Pollution”. He is currently developing conference control protocols and conferencing systems as a scientist in the “Digital Media a...
