A 4.1 million m(3) coal ash release into the Emory and Clinch rivers in December 2008 at the Tennessee Valley Authority's Kingston Fossil Plant in east Tennessee, USA, prompted a long-term, large-scale biological monitoring effort to determine if there are chronic effects of this spill on resident biota. Because of the magnitude of the ash spill and the potential for exposure to coal ash-associ...

Synthetic Aperture RADAR (SAR) imaging system is used to monitor the marine system. Oil spill pollution plays a significant role in damaging marine ecosystem. One main advantages of SAR is that it can generate imagery under all weather conditions. In a SAR image dark spots can be generated by number of phenomena. The dark spots may be of algae, low wind areas, coastal areas and oil spills. The ...

A sewer main serving a large municipal wastewater system ruptured, discharging approximately 3,000,000 gallons (11,355,000 L) of raw human sewage into a multi-branched tidal creek estuary along the US East Coast. The biochemical oxygen demand caused severe hypoxia in the system, causing a large fish kill. The sewage load led to high fecal coliform bacteria concentrations in the creek (maximum o...

Among many discussions on effective response strategies during oil spill operations at sea, this paper elaborates comprehensive information combat strategy and lesson learnt from Balikpapan Spill incident. The author tries to shown the effectiveness of assessment surveillance prior operation, monitoring after operation. point out used by OSCT Indonesia as National Oil Response Organization resp...

Reducing the risk of oil spills and mitigating the prospect of terrorist attacks and sabotage is essential for protecting the environment and reducing economic losses. Oil spill surveillance constitutes a critical component of an effective security program and oil spill disaster management. Advances in remote sensing technologies can help to identify potential threats and minor spills before th...

The occurrence of oil spills is a global problem that requires a complex set of scientists, engineers, governments, corporations, and communities to address. The objective of this special feature is to understand the dynamic process of adaptation in the face of economic and ecological vulnerabilities as related to major oil spills, such as the Deepwater Horizon oil spill in the United States in...

We examined hepatic EROD activity, as an indicator of CYP1A induction, in Barrow's goldeneyes captured in areas oiled during the 1989 Exxon Valdez spill and those from nearby unoiled areas. We found that average EROD activity differed between areas during 2005, although the magnitude of the difference was reduced relative to a previous study from 1996/1997, and we found that areas did not diffe...

National labour market institutions interact across national boundaries when product markets are global. Labour market policies can thus entail spill-overs, which suggest that there are benefits from international policy coordination. This paper studies the effects of wage subsidies in an international duopoly model with unionized labour markets. The authors document both positive and negative ...

The ectoparasitic mite Varroa destructor is a major global threat to the Western honeybee Apis mellifera. This mite was originally a parasite of A. cerana in Asia but managed to spill over into colonies of A. mellifera which had been introduced to this continent for honey production. To date, only two almost clonal types of V. destructor from Korea and Japan have been detected in A. mellifera c...

National labour market institutions interact across national boundaries when product markets are global. Labour market policies can thus entail spill-overs, a fact widely ignored in the academic literature. This paper studies the effects of wage subsidies in an international duopoly model with unionised labour markets. We document both positive and negative spill-over effects and discuss the be...
