Satellite synthetic aperture radar (SAR) is frequently used during oil spill response efforts to identify oil slick extent, but suffers from the major disadvantages of potential long latency between when a spill occurs and when a satellite can image the site and an inability to continuously track the spill as it develops. We show using data acquired with the Uninhabited Aerial Vehicle SAR (UAVS...

Renewed political and commercial interest in the resources of the Arctic, the reduction in the extent and thickness of sea ice, and the recent failings that led to the Deepwater Horizon oil spill, have prompted industry and its regulatory agencies, governments, local communities and NGOs to look at all aspects of Arctic oil spill countermeasures with fresh eyes. This paper provides an overview ...

Pool and vapor cloud characteristics of an acetone spill issuing from the downstream wall of a flow obstruction oriented perpendicular to a uniform flow were investigated experimentally. Data indicate that the spill event was largely governed by the temperature of the surface in relation to the boiling point of the spilled liquid. The free stream velocity (ranging from 0.75 to 3.0m/s) also impa...

OBJECTIVES The purpose of this study was to compare the physical and mental health status of disaster victims according to disaster types, such as a typhoon disaster and an oil spill disaster, and to suggest adequate health care services for them. METHODS A total of 484 people who suffered disasters were selected for this study, and data were collected from July to August, 2008. The data-set ...

By combining news coverage and survey data from the BP oil spill of 2010, this study demonstrates how the media played an important role in connecting the disaster to President Obama. Rather than criticizing Obama from the outset, the spill reporting escalated from a period of event-based, factual coverage to a highly politicized phase of governmental blame attribution. We utilize a natural exp...

Objectives: We analyze patterns in environmental views of Gulf Coast residents, in the wake of the 2010 oil spill. To what extent do spill-related and other environmental views vary with individual characteristics, personal experience with the spill, or characteristics of place? Methods: About 2,000 residents of selected coastal regions in Louisiana and Florida were interviewed by telephone in ...

In-situ burning is the combustion of a spill product at the site of the spill (in situ is Latin for “in place”.) In-situ burning of oil may offer a logistically simple, rapid, inexpensive, and relatively safe means for reducing the net environmental impact of an oil spill. Because a large portion of the oil is converted to gaseous combustion products, the need for collection, storage, transport...

The surface plasmon in simple metal clusters is red-shifted from the Mie frequency, the energy shift being significantly larger than the usual spill-out correction. Here we develop a variational approach to the RPA collective excitations. Using a simple trial form, we obtain analytic expressions for the energy shift beyond the spill-out contribution. We find that the additional red shift is pro...

This work was aimed at assessing the effect of crude oil spill on the diversity and abundance of plankton communities of the Njaba River area of the spill. Sampling was carried out in 1999 in nine clusters of stations, three each from upstream, spill-point and downstream transects. Each cluster was made up of three perpendicular sampling points across the river. Standard methods were used in co...
