Understanding marine eutrophication from agricultural runoff in semi enclosed areas: a short review in the Gulf of Geras, Greece


Karydis M.


The understanding of marine eutrophication in semi enclosed areas due to agricultural runoff, assumes a more integrated approach taking into account the agricultural watershed, seasonal patterns of soil nutrients, rates of erosion and vegetation types. In the present case study in the Gulf of Geras...

Toxicity of Organophoshorous pesticides to the marine alga Tetraselmis Suecica


Vagi M.C., Kostopoulou M.N., Petsas A.S., Lalousi M.E., Rasouli Ch. and Lekkas T.D.


Organophoshorous pesticides are widely used in agriculture, because most of them are high effective and low persistent. Yet their increased usage has elicited extensive research into pesticide effects on non-target organisms, such as algae. Algae are of vital importance in the primary production of...

Chemical composition of precipitation at coastal and marine sampling sites in Mexico


Ceron R.M., Ceron J.G., Cordova A.V., Zavala J. and Muriel M.


Chemical characteristics of wet precipitation were measured in Acapulco, Cancun, Tapachula, Puerto Morelos and Tropical Pacific Ocean; from August 1999 to October 2001. The samples were analyzed for pH, Na+, K+, Ca2+, Mg2+, NH4 +, SO4 2-, NO3 - and Cl-. Ionic abundance revealed a significant...

Estimation of Anisotropies in Chlorophyll A spatial distributions based on satellite data and variography by


Michelakaki M. and Kitsiou D.


Sea eutrophication is a natural process, however in many cases is considered one of the major forms of water pollution affecting coastal areas, lakes and reservoirs all over the world. Many methodologies have been developed for assessing eutrophication and during the last decades, the contribution...

Modeling The Saltwater Intrusion Phenomenon In Coastal Aquifers - A Case Study In The Industrial Zone Of Herakleio In Crete by


Papadopoulou M.P., Karatzas G.P., Koukadaki M.A. and Trichakis Y.


Salinity is a common problem in Greek islands, especially, during the summer period when the saltwater intrusion becomes more severe due to extensive over pumping. In the past few years, the industrial zone of the City of Herakleio in Crete appears to have an increasing water demand as result of the...
