[1] Total alkalinity (AT) was measured during the Meteor 51/2 cruise, crossing the Mediterranean Sea from west to east. AT concentrations were high ( 2600 mmol kg ) and alkalinity-salinity-correlations had negative intercepts. These results are explained by evaporation coupled with high freshwater AT inputs into coastal areas. Salinity adjustment of AT revealed excess alkalinity throughout the ...

Recent research studies have highlighted the decrease in the coverage of Mediterranean seagrasses due to mainly anthropogenic activities. The lack of data on the distribution of these significant aquatic plants complicates the quantification of their decreasing tendency. While Mediterranean seagrasses are declining, satellite remote sensing technology is growing at an unprecedented pace, result...

The bioinvasion of the Mediterranean from the Red Sea via the Suez Canal, called Lessepsian bioinvasion, was used as a way to uncover the invading potential of different genetic clades. Populations of blotchfin dragonet Callionymus filamentosus were assessed, based on 2 mitochondrial markers (control region and cytochrome oxidase 1) and 2 nuclear markers (2nd intron of the ribosomal protein S7 ...

Summertime tropospheric ozone variability over the Mediterranean basin observed with IASI C. Doche, G. Dufour, G. Foret, M. Eremenko, J. Cuesta, M. Beekmann, and P. Kalabokas Laboratoire Inter-universitaire des Systèmes Atmosphériques (LISA), Universités Paris-Est Créteil et Paris Diderot, CNRS, Créteil, France Academy of Athens, Research Center for Atmospheric Physics and Climatology, Athens, ...

Ozone uptake was studied in a pine forest in Tenerife, Canary Islands, an ecotone with strong seasonal changes in climate. Ambient ozone concentration showed a pronounced seasonal course with high concentrations during the dry and warm period and low concentrations during the wet and cold season. Ozone uptake by contrast showed no clear seasonal trend. This is because canopy conductance signifi...

Remote sensing of bromine monoxide (BrO) from the Ozone Monitoring Instrument (OMI) and other satellite instruments opens the possibility to extend our understanding of atmospheric halogen chemistry from local-scale studies to global scales. In the Arctic springtime boundary layer, these bromine monoxide radicals and bromine atoms are known to destroy ozone [1] and oxidize mercury [2], leading ...

introduction zayanderood basin is one of the major internal river basins in the central iran, where zayanderood river is the only permanent river. fluctuations in rainfall in recent years have affected different areas of iran. because of the dependence of the provinces of isfahan, yazd, and kerman on water resources of this basin, changes and fluctuations in precipitation within this watershed ...

[1] Two sets of sea surface temperature/sea ice changes are used to test the sensitivity of tracer transport to the pattern of warming in the doubled CO2 climate. One set (2CO2WT) has greater tropical and high latitude sea surface temperature changes than the other (2CO2), although both fall within the range of plausible response. Simulations were done both with and without interactive ozone. R...

The gills of 63 specimens of the Atlantic bluefin tuna Thunnus thynnus (Linnaeus) (Osteichthyes: Scombridae) from three localities of the Mediterranean (Sardinian, Tyrrhenian and Levantine Seas) were examined for metazoan parasites. The parasite fauna of T. thynnus from the Sea of Sardinia included 11 species: five didymozoid trematodes, three capsalid and one hexostomid monogeneans, and one ca...
