Introduction Due to the different geomorphological and morph dynamic forces of the coastal area, they form different areas. Each of these areas requires its own coastal management. While in our country, coastal management is done without considering the characteristics and coastal characteristics of each coast. In this study, in order to classify coasts and determine coastal cells, morph dynam...

BACKGROUND Indo-Pacific high island streams experience extreme hydrological variation, and are characterised by freshwater fish species with an amphidromous life history. Amphidromy is a likely adaptation for colonisation of island streams following stochastic events that lead to local extirpation. In the Wet Tropics of north-eastern Australia, steep coastal mountain streams share similar physi...

The interaction of open and coastal oceans in a midlatitude ocean basin is investigated in light of Rossby and coastal Kelvin waves. The basinwide pressure adjustment to an initial Rossby wave packet is studied both analytically and numerically, with the focus on the low-frequency modulation of the resulting coastal Kelvin wave. It is shown that the incoming mass is redistributed by coastal Kel...

Coastal fisheries are an important. component of the fisheries sector and rural economy of tropical developing countries in Asia generating food, employment and foreign exchange. In 1994, marine landings of these countries were about 13.3 million t (roughly 16% of world marine landings), most originating from coastal areas. The coastal fishery resources consist dominantly of species with relati...

this study was conducted to determine physiological and morphological variation of strains of the ectomycorrhizal fungus hebeloma cylindrosporum associated with pinus pinaster and its consequence on the symbiotic processes in coastal forests adjacent to bordeaux, south west france, from 2003-2005. mycelial cultures were conducted in the laboratory on a rich medium (ymg). diploid fungal strains ...

The social and economic benefits of the coastal zone make it one of the most treasured environments on our planet. Yet it is vulnerable to increasing anthropogenic pressure and climate change. Coastal management aims to mitigate these pressures while augmenting the socio-economic benefits the coastal region has to offer. However, coastal management is challenged by inadequate sampling of key en...

Using data collected from 62 coastal stations worldwide from the Aerosol Robotic Network (AERONET) from 2002-2011, accuracy assessments are made for coastal aerosol optical depth (AOD) retrieved from MODIS aboard the Aqua satellite. It is found that coastal AODs (at 550 nm) characterized respectively by the MODIS Dark Land (Land) surface algorithm, the Open Ocean (Ocean) algorithm, and AERONET ...

The natural environment is unequivocally the life support for all human systems. Far for being a luxury available only to those who can afford it, successful environmental management will increasingly become the basis for the success or failure of the economics and social systems of entire countries. In the last two decades, concern has been expressed about possible effects of climate change in...
