The new National Ocean Policy calls for actions to improve understanding of and capacity to respond to ocean acidification, recognizing the potential adverse impacts of an acidifying sea upon marine ecosystems. The effects of ocean acidification could significantly affect strategies for developing practices towards the sustainability of ocean resources. Basic research concerning the nature, extent and impact of ocean acidification on oceanic environments in the past, present and future is required. Research challenges include: Understanding the geochemistry and biogeochemistry of ocean acidification; Understanding how ocean acidification interacts with biological, chemical and physical processes at the organismal level, and how such interactions impact the structure and function of ecosystems, e.g. through life histories, adaptive evolution, food webs, biogeochemical cycling, and interactions with other changes in the ocean (e.g., temperature, stratification, circulation patterns); and Understanding how the earth system history informs our understanding of the effects of ocean acidification on the present day and future ocean. The Ocean Acidification program is in its fifth and anticipated last year of competition. We expect this to be the last solicitation specifically targeting Ocean Acidification.

The Arctic Sciences and other NSF programs support projects that contribute to the development of the next generation of researchers and scientific literacy for all ages through education, outreach, and broadening participation in science, technology, engineering, and mathematics. Program representatives from polar and other non-polar NSF programs that support arctic research coordinate across NSF, including joint review and funding of arctic proposals and mutual support of special projects with high logistical costs.

The Directorates for Engineering (Division of Chemical, Bioengineering, Environmental & Transport Systems), Geosciences (Division of Atmospheric and Geospace Sciences) and Mathematical and Physical Sciences (Divisions of Astronomical Sciences and Physics) of the National Science Foundation (NSF) and the Office of Science/Office of Fusion Energy Sciences (SC/FES) of the Department of Energy (DOE) are continuing in FY2014 the joint Partnership in Basic Plasma Science and Engineering begun in FY1997 and continued in FY2000, FY2003, FY2006 and FY2009. As stated in the original solicitations (NSF 97-39, NSF 99-159, NSF 02-84, NSF 05-619, NSF 09-596), which are superseded by the present solicitation, the goal of the initiative is to enhance plasma research and education in this broad, multidisciplinary field by coordinating efforts and combining resources of the two agencies. The current solicitation also encourages submission of proposals to perform basic plasma experiments on the Large Aperture Plasma Device (LAPD) at the University of California, Los Angeles (UCLA), a unique user facility designed to serve the needs of the broader plasma community.

The goal of research funded under the interdisciplinary P2C2 solicitation is to utilize key geological, chemical, atmospheric (gas in ice cores), and biological records of climate system variability to provide insights into the mechanisms and rate of change that characterized Earth's past climate variability, the sensitivity of Earth's climate system to changes in forcing, and the response of key components of the Earth system to these changes.  Important scientific objectives of P2C2 are to: 1) provide comprehensive paleoclimate data sets that can serve as model test data sets analogous to instrumental observations; and 2) enable transformative syntheses of paleoclimate data and modeling outcomes to understand the response of the longer-term and higher magnitude variability of the climate system that is observed in the geological and cryospheric records.

Integrated Earth Systems (IES) is a program in the Division of Earth Sciences (EAR) that focuses on the continental, terrestrial and deep Earth subsystems of the whole Earth system.  The overall goal of the program is to provide opportunity for collaborative, multidisciplinary research into the operation, dynamics and complexity of Earth systems at a budgetary scale between that of a typical project in the EAR Division's disciplinary programs and larger scale initiatives at the Directorate or Foundation level. Specifically, IES will provide research opportunities for the study of Earth systems from the core of the Earth to the top of the critical zone with a specific focus on subsystems that include continental, terrestrial and deep Earth subsystems at all temporal and spatial scales (NROES, 2012).  IES will provide opportunities to focus on Earth systems connected to topics which include (but are not limited to) the continents; the terrestrial, surficial Earth systems including physical, chemical and biotic dimensions; linkages among tectonics, climate, landscape change, topography and geochemical cycles including core and mantle processes.

The Hydrologic Sciences Program focuses on the fluxes of water in the environment that constitute the water cycle as well as the mass and energy transport function of the water cycle. The Program supports the study of processes from rainfall to runoff to infiltration and streamflow; evaporation and transpiration; the flow of water in soils and aquifers; and the transport of suspended, dissolved, and colloidal components. The Hydrologic Sciences Program retains a strong focus on linking fluxes of water and the components carried by water across boundaries between various interacting facets of the terrestrial system and the mechanisms by which these fluxes co-organize over a variety of timescales and/or alter fundamentals of water cycle interactions within the terrestrial system. The Program is also interested in how water interacts with the landscape and the ecosystem as well as how the water cycle and its coupled processes are altered by land use and climate. Studies may address physical, chemical, and biological processes that are coupled directly to water transport. Projects submitted to Hydrologic Sciences commonly involve expertise from basic sciences, engineering and mathematics; and proposals may require joint review with related programs. The Hydrologic Sciences Program will also consider synthesis projects.

Supports research on the natural evolution of Earth's climate with the goal of providing a baseline for present variability and future trends through improved understanding of the physical, chemical, and biological processes that influence climate over the long-term. Competitive proposals will address specific aspects of scientific uncertaintyfor their proposed research. All four Divisions in the Geosciences Directorate have joined in creating the annual Paleo Perspectives on Climate Change (P2C2) competition in paleoclimate global change research. Researchers are encouraged to consider the P2C2 competitionas a possible source of support for their global change research. Since proposals eligible for funding in the P2C2 competition are not eligible for funding in the Paleoclimate Program, researchers are strongly advised to contact the Director of the Paleoclimate Program for guidance as to the suitability of their proposed research for either program.

Benefit-Cost Analysis is a widely employed approach for evaluating the economic consequences of environmental decisions. For environmental quality improvements, particularly those involving air pollution controls, major investments have been made in data collection and modeling methods. As a result, public and private stakeholders have well-developed tools available to inform their understanding of air pollution policies. America's water resources are also at risk of degradation from chemical and microbial pollutants and changing climatic conditions; however, the ability to estimate the benefits of water quality improvements has lagged behind analogous work for air quality. The U.S. GAO (2014) recently noted the challenges associated with valuing water quality. In addition, how differences in spatial scales impact water quality benefits is not well understood. It is recognized that actions that improve water quality in headwater streams, for example, can affect the quality of downstream waters, thereby supplying benefits far from the site of action. The U.S. EPA is interested in supporting research to improve non-use valuation methods that will enable public and private stakeholders to better evaluate water quality for the Nation's inland fresh water small streams, lakes and rivers, estuaries, coastal waters, and the Great Lakes.  For purposes of this RFA, small streams are defined as streams that are perennial and wadeable. 

The Geobiology and Low-Temperature Geochemistry Program focuses on geochemical processes in terrestrial Earth's surface environmental systems, as well as the interaction of geochemical and biological processes. The program supports field, laboratory, theoretical, and modeling studies of these processes and related mechanisms at all spatial and temporal scales. Studies may address: 1) inorganic and/or organic geochemical processes occurring at or near the Earth's surface now and in the past, and across the broad spectrum of interfaces ranging in scale from planetary and regional to mineral-surface and supramolecular; 2) the role of life in the transformation and evolution of Earth's geochemical cycles; 3) surficial chemical and biogeochemical systems and cycles, including their modification through environmental change and human activities; 4) low-temperature aqueous geochemical processes; 5) mineralogy and chemistry of earth materials; 6) geomicrobiology and biomineralization processes; and 7) medical mineralogy and geochemistry. The Program encourages research that focuses on geochemical processes as they are coupled with physical and biological processes in the critical zone. The Program also supports work on the development of tools, methods, and models for the advancement of low-temperature geochemistry and geobiology. The Geobiology and Low-Temperature Geochemistry Program is interested in supporting transformational and cutting-edge research. The Program is highly interdisciplinary and interfaces with other programs within the Earth Surface Section and with programs in biology, chemistry and engineering.
