Number: 98-869 Title: Marine Dead Zones: Understanding the Problem Authors: Eugene H. Buck, Resources, Science, and Industry Division Abstract: Legislation has been introduced in the 110th Congress to reauthorize and amend the Harmful Algal Bloom and Hypoxia Research and Control Act. As knowledge and understanding have increased concerning the possible impacts of hypoxia, congressional interest in monitoring and addressing the problem has grown. The issue of hypoxia is seen as a search for (1) increased scientific knowledge and understanding of the phenomenon, as well as (2) cost-effective actions that might diminish the size of hypoxic areas by changing practices that promote their growth and development. This report presents an overview of the causes of hypoxia, the U.S. areas of most concern, federal legislation, and relevant federal research programs. Pages: 13 Date: August 13, 2007
