With the frequent occurrence of marine oil spill and the serious environmental pollution as well as enormous economic losses it causes, there is a growing demand for oil spill emergency response. It becomes a trend to research on spatial information analysis and publishing based on GIS. Compared with the expensive and system-huge commercial software, open source platform which is free and small...

Oil spill is one of major marine environmental challenges. The main impacts of this phenomenon are preventing light transmission into the deep water and oxygen absorption, which can disturb the photosynthesis process of water plants. In this research, we utilize SpecTIR airborne sensor data to extract and classify oils spill for the Gulf of Mexico Deepwater Horizon (DWH) happened in 2010. For t...

Killer whales were photographed in oil after the 1989 ‘Exxon Valdez’ oil spill, but preliminary damage assessments did not definitively link mortalities to the spill and could not evaluate recovery. In this study, photo-identification methods were used to monitor 2 killer whale populations 5 yr prior to and for 16 yr after the spill. One resident pod, the AB Pod, and one transient population, t...

We present a methodology to detect oil spills using MODIS near-infrared sun glittered radiance imagery. The methodology was developed by using a set of seven MODIS images (training dataset) and validated using four other images (validation dataset). The method is based on the ratio image R = L'GN/LGN, where L'GN is the MODIS-retrieved normalized sun glint radiance image and LGN the same quantit...

Genomic and physiological responses in Gulf killifish (Fundulus grandis) in the northern Gulf of Mexico have confirmed oil exposure of resident marsh fish following the Macondo blowout in 2010. Using these same fish, we evaluated otolith microchemistry as a method for assessing oil exposure history. Laser-ablation inductively-coupled-plasma mass spectrometry was used to analyze the chemical com...

mangroves are one of the main important species which have critical function in ecologicalprocesses in the coastal habitats. recent studies have focused on long term effects such as biological andchemical responses and reactions of ecosystems. in this research, short term response of avicennia marina’spneumatophores as one of substantial parts of mangroves has been considered while facing the o...
