Abstract
ABSTRACT This study identifies research needed to assess the ecological effects and efficiency of various spill cleanup methods for oiled salt marshes. This is part of a larger program with the goal of developing ecologically based cleanup methods for a variety of shoreline habitats using controlled shoreline oiling plus various cleanup methods, preceded and followed by ecological monitoring. The information provided by these experiments will strengthen the scientific base available to support decision makers during spills and provide a sound approach to spill response planners. The first phase of the program has involved the design of a proposed experiment and selection of a site. A literature review has been completed as well as an evaluation of state and federal permitting procedures for experimental shoreline oiling. Development of the field study, which has yet to be implemented, included the following components.Identified a Spartina marsh as the priority habitat for the first phase of the programSelected a proposed experimental site in LouisianaProposed the treatment methods to be evaluated, such as flushing and vegetation cropping Previous controlled oil spill experiments have provided valuable data on the effects and efficiency of different cleanup techniques in a variety of habitats. More can be learned by such experimental oilings, where pre-spill data, dosage, and pre- and post-spill monitoring are controlled, than it is possible to learn from studying spills of opportunity.
