The Hebei Spirit oil spill (HSOS) in December 7, 2007 spilled approximately 10,900 tons of crude oil in about 10 km off the Taean coasts in South Korea. We first summarize and overview, in the present study, the current status of environmental and ecological effects of the HSOS focusing on i) pollution status for surrounding environment (water, sediment, and porewater), ii) biological effects o...

My objectives for this study were the following: (1) To work with Drs Holliday and Donaghay to deploy autonomous acoustical and optical instrumentation at eight coastal US sites, (2) to quantify the temporal occurrence and spatial distribution of thin planktonic layers at eight coastal US sites, (3) to assess the hydrography at each of the coastal sites in order to provide a physical context wi...

A 3D hydrodynamic/pollutant transport model was used to simulate the currents and pollutant transport in coastal areas. The bathymetric and shoreline data was provided to the model via a GIS module that operates in the ArcView GIS environment. The module is efficient and capable of generating bathymetric rectangular grids and shorelines of different resolution for open and closed boundary scena...

Coastal rivers often generate buoyant plumes at their mouth following high inflow rate events. This coastal water, especially in flooding season, collects freshwater runoff with a large number of sediments, which significantly affects the environment of the continent shelf. In the present study, the dynamics of a plume on a Southern Hemisphere coast has been studied using a 3D hydrodynamic mode...

The study was designed to assess the environmental and health risks arising from intensive poultry production in Kwara State, Nigeria. A total of 120 poultry farmers in Kwara State under the Poultry Association of Nigeria (PAN) were selected randomly for the study, and structured questionnaires were administered. The data collected were analyzed using descriptive statistics, chi-square test, an...
