A crawling Remotely Operated Vehicle (ROV) has been developed for scientific activities within coastal and estuarine regions of the ocean for multiple research activities such as environmental impact assessment and integrated coastal zone management. The Modular Amphibious Research Crawler (MARC-1) ROV is designed to operate underwater and in the surfzone to a depth of five meters. The vehicle ...

For analyzing basic marine and coastal characteristics we selected the potential sites where shrimp culture could be developed in a large coastal zone, Bahia Magdalena, Baja California Sur, Mexico. Based on our analysis, 6 sites were preselected and field stages of work were then developed to assess the precise suitability of each site in order to develop the proposed aquaculture activities. In...

The objective of the present study was to conduct a probabilistic assessment of risk posed by copper found in the coastal marine environment of China from 2005 to 2012. This was achieved by applying a tiered ecological risk assessment (ERA) approach for characterization of risks of concentrations of copper from nationwide marine water monitoring program. The results show that from 2005 to 2012 ...

Coastal visits not only provide psychological benefits but can also contribute to the accumulation of rubbish. Volunteer beach cleans help address this issue, but may only have limited, local impact. Consequently, it is important to study any broader benefits associated with beach cleans.

The distribution of heavy metals in El-Mex Bay located in Northern Egypt was studied. Eight metals (Cd, Cr, Co, Cu, Zn, Pb, Mn and Fe) were determined in water, Suspended Particulate Matter (SPM) and sediments. The Bay presents higher metal concentrations in aqueous Cd, Co and Pb are above the chronic freshwater quality criteria for aquatic life. Most of the dissolved trace metals displayed a n...
