Historic Oil Spills

An oil spill is a release of crude oil, or other liquid petroleum hydrocarbon, into the environment due to human activity.  On land, oil spills are usually localized and thus their impact can be eliminated relatively easily. In contrast, marine oil spills may result in oil pollution over large areas and present serious environmental hazards.  Oil spills include releases of crude oil from tankers, offshore platforms, drilling rigs and wells, as well as spills of refined petroleum products (such as gasoline, diesel) and their by-products, and heavier fuels used by large ships such as bunker fuel, or the spill of any oily refuse or waste oil.

Large oil spills have the potential to cause serious ecological risk (primarily for sea birds and mammals) and result in long-term environmental disturbances (mainly in coastal zones) and economic impact on coastal activities (especially on fisheries, mariculture, and tourism).

Graphing Changes in Marine Life Abundance Last Updated on 2011-06-04 00:00:00 This activity developed by NOAA will guide you through making a study of the marine life occupying a section, or quadrat, of Mearns Rock (a boulder in Prince William Sound, Alaska, that was oiled in 1989 by the Exxon Valdez oil spill). For your study, you'll use a series of zoomed-in photos of that quadrat. Each shows a different year from 1990 to 2009. Your goal will be to see how the percent cover of mussels, barnacles, and Fucus gardneri (a kind of seaweed, also called rockweed) in this study area has changed during those 19 years. As you complete this project, you'll be using the same method used by real marine biologists. To study how marine life abundance changes from one year to the next, marine biologists sometimes section off a small plot of land that's representative of the particular habitat they're studying (for example, a rocky shoreline or a bog). They use a frame... More »
Oil and water just don't mix Last Updated on 2011-05-18 00:00:00 Oil and water just don’t mix; opinions on deepwater exploration are just as polar. This unit provides teachers with resources to teach about oil in the marine environment and to bring these issues to the surface. Lesson 1: Students will use technology to research current affairs on environmental issues pertaining to oil spills. Students will gain a background understanding of the impact of the Deep Water Horizon spill. Students will make judgments about the efficacy of cleanup response.Students will compare and contrast the efficacy of response to various oil spills.Students will discuss the importance of oil to our society. Students will investigate the chemical properties of oil. Lesson 2:Students will gain an understanding of the environmental impacts of oil to an aquatic community. Students will investigate clean-up methods for oil, highlighting the distinctions... More »
