Despite that ＂pollution damage＂ in these treaties does not exclude damage to marine biodiversity, the fact that damage to marine biodiversity is not mentioned in this regime arouses the question of compensability of damage to marine biodiversity under the regime. This article attempts to investigate this question from the perspectives of the relationship between marine environmental damage and damage to marine biodiversity and the possibility of compensation for damage to marine biodiversity under the regime. While the findings of this article reveal that the regime cannot provide sufficient compensation for such damage, this article in the conclusion offers some suggestions for the sake of remedying of damaged marine biodiversity under the regime.展开更多

This study presents a new approach to detect and forecast oil slick trajectory movements. The oil slick trajectory movements is based on the tidal current effects and Fay's algorithm for oil slick spreading mechanisms. The oil spill trajectory model contains the integration between Doppler frequency shift model and Lagrangian model. Doppler frequency shift model implemented to simulate tidal current pattern from RADARSAT data while the Lagrangian model used to predict oil spill spreading pattern. The classical Fay's algorithm was implemented with the two models to simulate the oil spill trajectory movements.The study shows that the slick lengths are effected by tidal current V component with maximum velocity of 1.4 m/s. This indicates that oil slick trajectory path is moved towards the north direction. The oil slick parcels are accumulated along the coastline after 48 h. The analysis indicated that tidal current V components were the dominant forcing for oil slick spreading.展开更多

The structure of aerogel was analyzed by scanning electron microscopy（SEM） and X-ray diffraction（XRD） while the density and compressive strength of the samples were studied separately. Results reveal that porous network structure of the KGM nano microfibril aerogel is constructed by intermolecular hydrogen bonds in random and interpenetrate way. The nano microfibril structure presents in the KGM aerogel,which is an important reason of its high density and compressive strength. There is a potential application for this unique nano microfibril aerogel in the absorption of biodegradation bacteria to solve problems in marine oil spill pollution.展开更多
