The unprecedented magnitude of the Deepwater Horizon oil spill presents significant challenges for oil spill responders and those tasked with assessing the impacts of the spill. Evaluating changes to ecosystem services—the benefits people receive from natural resources and processes—caused by the oil spill could expand the potential to capture and value the full breadth of impacts to the ecosystem and the public. This report assesse... More >>

Through direct exploration of the subseafloor, U.S.-supported scientific ocean drilling programs have significantly contributed to a broad range of scientific accomplishments in Earth science disciplines, shaping understanding of Earth systems and enabling new fields of inquiry. The programs' technological innovations have played a strong role in these accomplishments. The science plan for the proposed 2013-2023 program presents a strong case fo... More >>

Satellite measurements of ocean color provide a unique global perspective on the health of the ocean by allowing scientists to track changes in the abundance and productivity of phytoplankton, microscopic organisms that live in the ocean's surface waters and form the base of the marine food chain. Monitoring phytoplankton abundance can provide information on the ocean's essential functions and resources, which can be used to assess long-ter... More >>

Report in Brief >> California's draft Bay Delta Conservation Plan—a draft plan to conserve habitat for endangered and threatened species, while continuing to divert water to agriculture and domestic water users in central and southern California—is incomplete and contains critical scientific gaps. The Bay Delta is a large, complex ecosystem that supplies water from the state's wetter northern regions to the drier southern regions, and als... More >>

Report in Brief >> U.S. ocean research depends on a broad range of ocean infrastructure assets—the national inventory of ships and other platforms, sensors and samplers, computational and data systems, supporting facilities, and trained personnel. In order to ensure that essential infrastructure is available for both fundamental research and issues of social importance in 2030, a coordinated national plan for making future strategic investment...
