().   This article introduces the EU Horizon research project GRACE (Integrated oil spill response actions and environmental effects), which focuses on a holistic approach towards investigating and understanding the hazardous impact of oil spills and the environmental impacts and benefits of a suite of marine oil spill response technologies in the cold climate and ice-infested areas of the.

    Oil is a general term that describes a wide variety of natural substances of plant, animal, or mineral origin, as well as a range of synthetic compounds. Crude oil is a naturally occurring oil generated by geological and geochemical processes. A variety of petroleum products are then derived from this natural resource. Because their compositions vary, each type of crude oil or petroleum. Oil in the Arctic marine ecosystem originates mainly from two sources: drilling activity and oil spills during transportation. Drilling activity causes long-term exposure and thus chronic effects on Arctic marine ecosystems, such as changes in species composition, dominance and biomass, while oil spill effects are acute and can cause severe.

    Oil in the sea from anthropogenic sources, whether from spills or chronic releases, is perceived as a major environmental problem. Major oil spills occur occasionally and receive considerable public attention because of the obvious attendant environmental damage, including oil-coated shorelines and dead or moribund wildlife, especially oiled seabirds and marine mammals. Acute effects may be of. AbstractCalanus finmarchicus and Calanus glacialis are keystone zooplankton species in North Atlantic and Arctic marine ecosystems because they form a link in the trophic transfer of nutritious lipids from phytoplankton to predators on higher trophic levels. These calanoid copepods spend several months of the year in deep waters in a dormant state called diapause, after which they emerge in.

Introduction. Marine oil spills often refer to releases of liquid petroleum hydrocarbons into the ocean or coastal areas due to human activities (Li, Cai, Lin, Chen, & Zhang, ).They include the releases of crude oil from tankers, offshore platforms, drilling rigs, and wells; spills of refined petroleum products (such as gasoline and diesel) and their by-products; heavier fuels.

In the Arctic, the probable behaviour of spilt oil, and the nature of coastal and nearshore marine ecosystems likely to be affected by it, both differ from the situation in temperate waters, where the problem has regrettably become a familiar one.

Science of The Total Environment(4), DOI: /env   Marine mammals are common, highly visible, and charismatic species that are potentially vulnerable to oil contamination, yet we know surprisingly little about the effects of oil on either individuals or populations.

Excessive oil winning has depleted oil wells around the world and has led to expansion into areas like the Arctic that are less accessible and where oil.
