Oil stranded by the 1989 Exxon Valdez spill has persisted in subsurface sediments of exposed shores for 16 years. With annualized loss rates declining from approximately 68% yr(-1) prior to 1992 to approximately 4% yr(-1) after 2001, weathering processes are retarded in both sediments and residual emulsified oil ("oil mousse"), and retention of toxic polycyclic aromatic hydrocarbons is prolonged. The n-alkanes, typically very readily oxidized by microbes, instead remain abundant in many… Expand

Long-term persistence of oil from the Exxon Valdez spill in two-layer beaches
Oil spilt from the tanker Exxon Valdez more than 20 years ago still persists in the gravel beaches of Prince William Sound, Alaska. Field data and numerical modelling indicate that some of the oilExpand
Conditions of persistent oil on beaches in Prince William Sound 26 years after the Exxon Valdez spill
Abstract On March 24, 1989, the Exxon Valdez grounded on Bligh Reef in Prince William Sound, Alaska, spilling an estimated 10.8 million gallons of crude oil. Contrary to early projections, subsequentExpand
A Review of distribution and quantity of lingering subsurface oil from the Exxon Valdez Oil Spill
Abstract Remaining lingering subsurface oil residues from the Exxon Valdez oil spill (EVOS) are, at present, patchily distributed across the geologically complex and spatially extensive shorelines ofExpand
Distribution and weathering of crude oil residues on shorelines 18 years after the Exxon Valdez spill.
Sediment samples from 22 sites that were most heavily oiled in 1989 and known to contain the heaviest subsurface oil (SSO) deposits were taken based on multiple studies conducted since 2001, finding that most of the EVOS oil in PWS has been eliminated due to natural weathering. Expand
A tracer study in an Alaskan gravel beach and its implications on the persistence of the Exxon Valdez oil.
A lithium tracer study was conducted along two transects on one of these beaches, finding that the tracer stayed much longer in the oil-persisting, right trnsect (facing landwand), implying that the oil persistence along the right tran Sect was not due to the lack of nutrients during the bioremediation.

Exxon Valdez Oil Spill Restoration Project Final Report Final 2005-2006 LTEMP Oil Monitoring Report Restoration Project 050763
The Long Term Environmental Monitoring Program (LTEMP) has been sampling mussels (and some sediments) twice annually at ten sites in Port Valdez, Prince William Sound, and nearby Gulf of Alaska sitesExpand
Long term monitoring for oil in the Exxon Valdez spill region.
A decreasing trend appears in total PAH (TPAH) in tissues at all sites with current values below 100 ng/g dry weight, and this new low in TPAH likely represents ambient background levels. Expand
The influence of pressure on crude oil biodegradation in shallow and deep Gulf of Mexico sediments
The results indicated a modest inhibitory effect of pressure on biodegradation over the experimental range, however, the expansion of oil exploration to deeper waters opens the risk of spills at conditions at which pressure might have a more pronounced effect. Expand
Biodegradability of lingering crude oil 19 years after the Exxon Valdez oil spill.
Results indicated that lingering oil is biodegradable and Nutrient addition stimulated biodegradation compared to natural attenuation in all treatments regardless of the degree of weathering. Expand
Persistence and biodegradation of oil at the ocean floor following Deepwater Horizon
The extent of degradation over 4 y postspill for each of 125 petroleum hydrocarbons that contaminated the seafloor is assessed, finding strong evidence for extensive degradation of numerous petroleum biomarkers, notably including the native internal standard 17α(H),21β(H)-hopane, commonly used to calculate the extent of oil weathering.

Persistence of 10-year old Exxon Valdez oil on Gulf of Alaska beaches: the importance of boulder-armoring.
Oil stranded as a result of the 1989 Exxon Valdez spill has persisted for >10 years at study sites on Gulf of Alaska shores distant from the spill's origin, with a general lack of weathering of this subsurface oil over the last decade. Expand
The fate of the oil spilled from the exxon valdez.
It is estimated that approximately 20% of the spilled oil evaporated and underwent photolysis in the atmosphere; approximately 50% biodegraded either in-situ on beaches or in the water column; approximately 14% was recovered or disposed; < 1% remained in theWater column (except as biodegradation products); approximately 2% remained on intertidal shorelines; and approximately 13% remained as highly weathered residuals. Expand
Estimate of oil persisting on the beaches of Prince William Sound 12 years after the Exxon Valdez oil spill.
It is indicated that oil from the Exxon Valdez remains by far the largest reservoir of biologically available polycyclic aromatic hydrocarbons on beaches impacted by the spill and that biota dependent on these beaches risk continued exposure. Expand
Factors determining the long-term persistence of Exxon Valdez oil in gravel beaches
Abstract The largest amounts of, and the least weathered, oil found eight years after the Exxon Valdez oil spill occurred at depths of 25–50+ cm under the protective cover of a well-sortedExpand

Abstract For at least 5 yr after the Exxon Valdez spill, relatively unweathered oil mousse has persisted on the exposed rocky shores of Shelikof Strait 500 km from Prince William Sound, Alaska.Expand
