Carbon (C) sequestration through fertilization of phytoplankton with micronutrients and enhancement of the absorption and retention of atmospheric C by ocean biota heavily depends on the efficiency of the “biological pump”. The long-term effectiveness of this strategy depends on a net transfer of C from the upper ocean-atmosphere system to the deep ocean where the C is removed from contact with the atmosphere for an extended period of time. This C removal can be equated to the amount of C fixation by phytoplankton minus the C cycling and regeneration in the euphotic zone. If the regeneration efficiency is increased, then despite increased C fixation, no net loss (sequestration) of C will result. A reduction in cycling efficiency in the euphotic zone, on the other hand, will increase the effectiveness of the “biological pump” and thus C sequestration. The degree of organic matter biodegradation and recycling depends on the “reactivity” of compounds synthesized by the biota, which in turn, is controlled by the structural characteristic of these compounds. There is considerable evidence that different phytoplankton taxa differ substantially in their biogeochemical characteristics and it is likely that the relative abundance of different compounds synthesized by these distinct taxa, and even within …

A letter report issued by the Government Accountability Office with an abstract that begins "In fiscal year 2009, states spent nearly a third (31.6 percent) of all Medicaid expenditures on the most expensive Medicaid-only beneficiaries, who were 4.3 percent of total Medicaid beneficiaries. States spent another third (33.1 percent) on all other Medicaid-only beneficiaries, who represented 81.2 percent of total Medicaid beneficiaries. Among dual eligible beneficiaries, a similar pattern existed, with a small proportion of the population accounting for a disproportionate share of expenditures."

This report provides background information on key elements of the FBI terrorism investigative process, based on publicly available information. This report sets forth possible considerations for Congress as it executes its oversight role, including the extent to which intelligence has been integrated into FBI operations to support its counterterrorism mission and the progress the Bureau has made on its intelligence reform initiatives.

This report describes homegrown violent jihadists and the plots and attacks that have occurred since 9/11. It also outlines actions underway to build trust and partnership between community groups and government agencies and the tensions that may occur between law enforcement and engagement activities.

This report focuses on how domestic terrorism is conceptualized by the federal government and issues involved in assessing this threat's significance.

This report presents statistics regarding U.S. military casualties in the active Operation Enduring Freedom (OEF, Afghanistan), as well as operations that have ended: Operation New Dawn (OND, Iraq) and Operation Iraqi Freedom (OIF, Iraq). It includes statistics on post-traumatic stress disorder (PTSD), traumatic brain injury (TBI), amputations, evacuations, and the demographics of casualties. Some of these statistics are publicly available at the Department of Defense's (DOD's) website; others have been obtained through contact with experts at the DOD.

This report reviews the legislative history surrounding the enactment of the 1968 and 1976 amendments to the appointment of the FBI Director, as well as information on the nominees to the FBI Directorship since 1972. It also provides a legal overview of the extension of a Director's tenure.

This report provides examples of Administration "combating violent extremism" (CVE) activity and examines some of the risks and challenges evident in the "Strategic Implementation Plan for Empowering Local Partners to Prevent Violent Extremism in the United States" (SIP's) three objectives. The report also diagrams and briefly discusses the "future activities and efforts" outlined in the SIP for each of these three objectives.

This report provides a brief overview of the European Union's (EU's) accession process and Turkey's path to EU membership. The U.S. Congress has had a long-standing interest in Turkey as a NATO ally and partner in regional foreign policy and energy security issues.
