Observations from the network support weather forecasting, science research, and educational activities, and all data collected are made available to the public. This project will continue to maintain and operate the existing network. These data provide some of the only available weather observations in this very remote portion of the Earth. To ensure fidelity, observations are reviewed and checked for errors by a combination of automated methods and expert review, enabling the data to be used in a wide range of research areas. The project will be overseen by a team of scientists, researchers, and students, and a newly created AWS Advisory Board will provide independent input and guidance. The activities for this project will be focused on the continued operation of the AWS network, establishment of an AWS Advisory Board, student engagement and outreach activities. This project will continue to maintain the AWS systems while upgrading the real-time processing of meteorological data from the AWS network. The team will continue to adapt to changes communication methods to ensure that data is distributed widely and in a timely manner. Prior NSF investments in the Polar Climate and Weather Station (PCWS) are leveraged to develop a robust production version that can be reliably used year-round in Antarctica. AWS observations will be quality-controlled and placed into a database where the public will be able to search and select subsets of observations. To resolve conflicting radiation shield setups for temperature observations, the team plans to test different radiation shields (with and without aspiration) deployed for one year at South Pole Station. The project will be advised by an independent group of diverse peers through a newly developed AWS Advisory Board. The team will incorporate students from all levels in all aspects of the project, including in the research design, engineering and productions of the PCWS, and in field deployments. A concerted effort to engage the public will be undertaken via scaled-up interactions with television meteorologists from several states across the US to bring Antarctica to the public.

AGN are powered by matter falling onto supermassive black holes. The primary objective of this research is to undertake a study of AGN brightness fluctuations using light in multiple wavelengths. By studying the connections between the fluctuations at different wavelengths, we can learn what causes these fluctuations. The data produced under this project will be publicly released to enable other scientific investigations. The broader impacts of this project include the training of graduate students in the Fisk-Vanderbilt Masters-to-PhD Bridge program. In addition, the researcher will continue to work with the NAACP (ACT-SO) and First Discoveries programs as a science mentor, advisor and teacher for local pre-K and high school students and classrooms. The researcher has introduced a new process that uses repurposed Cosmic Microwave Background (CMB) data from the South Pole Telescope to produce millimeter-wavelength light curves of AGN with the goal of conducting a multi-wavelength correlation study. This study will be use the measured correlations between different wavelength emissions from AGN to better understand the origin and production of observed gamma-ray emissions. This project will fund the first large-scale effort to use CMB data for AGN monitoring and will provide a foundational observing program/strategy that will be implemented in future CMB experiments.

remarkable window on the evolution of Earth\u2019s climate and unique samples of the ancient atmosphere. The clear link between greenhouse gases and climate revealed by ice cores underpins much of the scientific understanding of climate change. Unfortunately, the existing data do not extend far enough back in time to reveal key features of climates warmer than today. COLDEX, the Center for Oldest Ice Exploration, will solve this problem by exploring Antarctica for sites to collect the oldest possible record of past climate recorded in the ice sheet. COLDEX will provide critical information for understanding how Earth\u2019s near-future climate may evolve and why climate varies over geologic time. New technologies will be developed for exploration and analysis that will have a long legacy for future research. An archive of old ice will stimulate new research for the next generations of polar scientists. COLDEX programs will galvanize that next generation of polar researchers, bring new results to other scientific disciplines and the public, and help to create a more inclusive and diverse scientific community. Knowledge of Earth\u2019s climate history is grounded in the geologic record. This knowledge is gained by measuring chemical, biological and physical properties of geologic materials that reflect elements of climate. Ice cores retrieved from polar ice sheets play a central role in this science and provide the best evidence for a strong link between atmospheric carbon dioxide and climate on geologic timescales. The goal of COLDEX is to extend the ice-core record of past climate to at least 1.5 million years by drilling and analyzing a continuous ice core in East Antarctica, and to much older times using discontinuous ice sections at the base and margin of the ice sheet. COLDEX will develop and deploy novel radar and melt-probe tools to rapidly explore the ice, use ice-sheet models to constrain where old ice is preserved, conduct ice coring, develop new analytical systems, and produce novel paleoclimate records from locations across East Antarctica. The search for Earth\u2019s oldest ice also provides a compelling narrative for disseminating information about past and future climate change and polar science to students, teachers, the media, policy makers and the public. COLDEX will engage and incorporate these groups through targeted professional development workshops, undergraduate research experiences, a comprehensive communication program, annual scientific meetings, scholarships, and broad collaboration nationally and internationally. COLDEX will provide a focal point for efforts to increase diversity in polar science by providing field, laboratory, mentoring and networking experiences for students and early career scientists from groups underrepresented in STEM, and by continuous engagement of the entire COLDEX community in developing a more inclusive scientific culture.

This technology may provide a scalable and affordable way to deploy dense seismic networks. Experimental Distributed Acoustic Sensing equipment will be tested in the Antarctic exploiting unused (dark) strands in the existing fiber-optic cable that connects the U.S. Amundsen-Scott South Pole Station to the Remote Earth Science and Seismological Observatory (SPRESSO) located about 7.5-km from the main station. Upon processing the seismic signals, the Distributed Acoustic Sensing may provide a new tool to structurally image firn, glacial ice, and glacial bedrock. Learning how Distributed Acoustic Sensing would work on the ice sheet, scientists can then check seismological signals propagating through the Earth\u0027s crust and mantle variously using natural icequakes and earthquakes events in the surrounding area. The investigators propose to convert at least 8 km of pre-existing fiber optic cable at the Amundsen-Scott South Pole station into more than 8000 sensors to explore the potential of Distributed acoustic sensing (DAS) as a breakthrough data engine for polar seismology. The DAS array will operate for about one year, allowing them to (1) evaluate and calibrate the performance of the DAS technology in the extreme cold, very low noise (including during the exceptionally quiet austral winter) polar plateau environment; (2) record and analyze local ambient and transient signals from ice, anthropogenic signals, ocean microseism, atmospheric and other processes, as well as to study local, regional, and teleseismic tectonic events; (3) structurally image the firn, glacial ice, glacial bed, crust, and mantle, variously using active sources, ambient seismic noise, and natural icequake and earthquake events.

What is the Universe made of? What is the mass scale of the neutrinos? When did the first stars and galaxies form and how was the Universe reionized? What is the Dark Energy that is accelerating the expansion of the Universe? The SPT plays a unique role in the pursuit of these questions. Its siting is ideal for ultra-low-noise imaging surveys of the sky at the millimeter and sub-millimeter radio wavelengths. The SPT is supported by the NSF\u0027s Amundsen-Scott South Pole Station, which is the best operational site on Earth for mm-wave sky surveys. This unique geographical location allows SPT to obtain extremely sensitive 24/7 observations of targeted low Galactic foreground regions of the sky. The telescope\u0027s third-generation, SPT-3G receiver has 16,000 detectors configured for polarization-sensitive observations in three millimeter-wave bands. The proposed operation includes five years of sky surveys to obtain ultra-deep measurements of a 1500 square degree field and to produce and publicly archive essential data products from the survey. The telescope\u0027s CMB temperatures and polarization power spectrum will play a central role in probing the nature of current tensions among cosmological parameter estimations from different data sets and determining if their explanation requires physics beyond the current LCDM model. The data will help constraining the Dark Energy properties that affect the growth of large structures through both the CMB lensing and abundance of galaxy clusters. The proposed operations also support SPT\u0027s critical role in the Event Horizon Telescope (EHT), a global array of telescopes to image the event horizon around the black hole at the center of Milky Way Galaxy. This award addresses and advances the science objectives and goals of the NSF\u0027s \"Windows on the Universe: The Era of Multi-Messenger Astrophysics\" program. The proposed research activity will also contribute to the training of the next generation of scientists by integrating graduate and undergraduate education with the technology development, astronomical observations, and scientific analyses of SPT data. Research and education are integrated by bringing research activities into the undergraduate classroom and sharing of forefront research with non-scientists extending it beyond the university through a well-established educational network that reaches a wide audience at all levels of the educational continuum. Through museum partnerships and new media, the SPT outreach and educational efforts reach large numbers of individuals while personalizing the experience.

The core team of researchers and engineers maintain the existing ICNO infrastructure at the South Pole and home institution, guaranteeing an uninterrupted stream of scientifically unique, high-quality data. The M\u0026O activities are built upon eight highly successful years of managing the overall ICNO operations after the start of science operations in 2008. Construction of ICNO was supported by NSF\u0027s Major Research Equipment and Facilities Construction (MREFC) account and was completed on schedule and within budget in 2010. Effective coordination of efforts by the core M\u0026O personnel and efforts by personnel within the IceCube Collaboration has yielded significant increases in the performance of this cubic-kilometer detector over time. The scientific output from the IceCube Collaboration during the past five years has been outstanding. The broader impacts of the ICNO/M\u0026O activities are strong, involving postdoctoral, graduate, and (in some cases) undergraduate students in the day-today operation \u0026 calibration of the neutrino detector. The extraordinary physics results recently produced by ICNO and its extraordinary location at South Pole have a high potential to excite the imagination of high school children and the public in general at a national and international level. The current ICNO/M\u0026O effort produces better energy and angular resolution information about detected neutrino events, has more efficient data filters and more accurate detector simulations, and enables continuous software development for systems that are needed to acquire and analyze data. This has produced data acquisition and data management systems with high robustness, traceability, and maintainability. The current ICNO/M\u0026O effort includes: (1) resources for both distributed and centrally managed activities, and (2) additional accountability mechanisms for \"in-kind\" and institutional contributions. Both are necessary to ensure that the detector maintains its capability to produce quality scientific data at the level required to achieve the detector\u0027s scientific discovery objectives. Recent ICNO discoveries of cosmic high-energy neutrinos (some reaching energies close to and over 2.5 PeV) and oscillating atmospheric neutrinos in a previously unexplored energy range from 10 to 60 GeV became possible because of the \"state-of-the-art\" detector configuration, excellently supported infrastructure, and cutting-edge science analyses. The ICNO has set limits on Dark Matter annihilations, made precision measurements of the angular distribution of cosmic ray muons, and characterized in detail physical properties of the Antarctic 2.5-km thick ice sheet at South Pole.

The model traces the expansion of the Universe, starting from initial conditions of a very high density and temperature state which is almost but not perfectly smooth, and it offers a comprehensive explanation for a broad range of now-known phenomena, including the abundance of light elements, the cosmic microwave background radiation, and the distribution of large scale structures. While the established \"Big Bang\" theory leaves open the question of explaining the initial conditions, current evidence is consistent with the entire observable Universe being spawned in a dramatic, exponential \"inflation\" of a sub-nuclear volume that lasted about one trillionth of a trillionth of a trillionth of a second. Following this short inflationary period, the Universe continues to expand, but at a less rapid rate. While the basic \"inflationary paradigm\" is accepted by most scientists, the detailed particle physics mechanism responsible for inflation is still not known. It is believed that this violent space-time expansion would have produced primordial gravitational waves now propagating through the expanding universe, thus forming a cosmic gravitational-wave background (CGB) the amplitude of which measures the energy scale of inflation. The CGB imprints a faint signature in the polarization of the Cosmic Microwave Background (CMB), and detecting this polarization signature is arguably the most important goal in cosmology today. This award will address one of the oldest questions ever posed by mankind, \"How did the Universe begin?\", and it does so via observations made at one of the most intriguing places on Earth, South Pole Station in Antarctica. The community-driven Astro2010 Decadal Survey described the search for the CGB as \"the most exciting quest of all\", emphasizing that \"mid-term investment is needed for systems aimed at detecting the (B-mode) polarization of the CMB\". In 2005, the NASA/DOE/NSF Task Force on CMB Research identified this topic as the highest priority for the field and established a target sensitivity for the ratio of gravitational waves to density fluctuations of r ~ 0.01. Such measurements promise a definitive test of slow-roll models of inflation, which generally predict a gravitational-wave signal around r~0.01 or above, producing CMB B-modes fluctuations that peak on degree angular scales. The ongoing BICEP series of experiments is dedicated to this science goal. The experiment began operating at South Pole in 2006 and has been relentlessly mapping an 800 square degree region of the sky in a region of low in Galactic foregrounds known as the Southern Hole. This award will support science observations and analysis for the CMB \"Stage 3\" science with the BICEP Array program that will measure the polarized sky in five frequency bands. It is projected to reach an ultimate sensitivity to the amplitude of inflationary gravitational waves of \"sigma r\" \u003c 0.005, extrapolating from achieved performance and after conservatively accounting for the Galactic dust, Galactic synchrotron radiation, and CMB lensing foregrounds. This measurement will offer a definitive test of most slow-roll models of Inflation, and will realize or exceed the goals set by the Task Force in 2005 for sensitivity. The project will continue to provide excellent training for undergraduate and graduate students and postdoctoral fellows (including those from underrepresented groups) in laboratories that have exceptional track records in this regard.

Excited primarily by deep convection, frontal activity, topography, and strong wind shears in the lower atmosphere, these waves transport energy and momentum upwards where they have a profound influence on the MLT dynamics. Most of the wave forcing is expected to occur at mid-and low-latitudes where such sources predominate. However, short-period waves (exhibiting similar characteristics to mid-latitude events) have now been detected in copious quantities from research sites on the Antarctic Peninsula and the coastal regions exhibiting strong anisotropy in their dominant horizontal motions (and hence their momentum fluxes). Radiosonde measurements have established the existence of ubiquitous gravity wave activity at South Pole but, to date, there have been no detailed measurements of the properties of short-period waves at MLT heights deep in the Antarctic interior. In particular, the South Pole Station is uniquely situated to investigate the filtering and penetration of these waves into the MLT region, a substantial fraction of which may be ducted waves traveling over vast geographic distances (several thousand km). Novel image measurements at South Pole Station combined with existing measurement programs will provide an unprecedented capability for quantifying the role of these gravity waves on the regional MLT dynamics over central Antarctica.

The analyses will include: methane isotopes (delta-13CH4 and delta-DCH4), light non-methane hydrocarbons (ethane, propane, and n-butane), sulfur gases (COS, CS2), and methyl halides (CH3Cl and CH3Br). The atmospheric burdens of these trace gases reflect changes in atmospheric OH, biomass burning, biogenic activity in terrestrial, oceanic, and wetland ecosystems, and industrial/agricultural activity. The goal of this project is to develop atmospheric histories for these trace gases over the last century through examination of depth profiles of these gases in South Pole firn air. The project will involve two phases: 1) a field campaign at South Pole, Antarctica to drill two firn holes and fill a total of ~200 flasks from depths reaching 120 m, 2) analysis of firn air at University of California, Irvine, Penn State University, and several other collaborating laboratories. Atmospheric histories will be inferred from the measurements using a one dimensional advective/diffusive model of firn air transport. This study will provide new information about the recent changes in atmospheric levels of these gases, providing about a 90 year long time series record that connects the earlier surface and firn air measurements to present day. The project will also explore the possibility of in- situ production of light non-methane hydrocarbons in firn air that is relevant to the interpretation of ice core records.

E) in 2007-2008; and a return traverse starting at South Pole Station and ending at Troll Station by a different route in 2008-2009. The project will investigate climate change in East Antarctica, with the goals of understanding climate variability in Dronning Maud Land of East Antarctica on time scales of years to centuries and determining the surface and net mass balance of the ice sheet in this sector to understand its impact on sea level. The project will also investigate the impact of atmospheric and oceanic variability and human activities on the chemical composition of firn and ice in the region, and will revisit areas and sites first explored by traverses in the 1960\u0027s, for detection of possible changes and to establish benchmark datasets for future research efforts. In terms of broader impacts, the results of this study will add to understanding of climate variability in East Antarctica and its contribution to global sea level change. The project includes international exchange of graduate students between the institutions involved and international education of undergraduate students through classes taught by the PI\u0027s at UNIS in Svalbard. It involves extensive outreach to the general public both in Scandinavia and North America through the press, television, science museums, children\u0027s literature, and web sites. Active knowledge sharing and collaboration between pioneers in Antarctic glaciology from Norway and the US, with the international group of scientists and students involved in this project, provide a unique opportunity to explore the changes that half a century have made in climate proxies from East Antarctica, scientific tools, and the culture and people of science. The project is relevant to the International Polar Year (IPY) since it is a genuine collaboration between nations: the scientists involved have complementary expertise, and the logistics involved relies on assets unique to each nation.

Although fluctuations in the relativistic particle population are extensively observed on satellites, little is known about the extent of associated precipitation into the ionosphere. Upon precipitation, these highly energetic particles penetrate to altitudes as low as 30-40 km, producing ionization, X-rays, and possibly affecting chemical reactions involving ozone production. It is proposed to continue recording the VLF beacon\u0027s signal at various Antarctic coastal stations (Palmer, Halley, etc). The broader impact of the proposed program includes the synergistic use of the South Pole VLF beacon with ongoing satellite-based measurements of trapped and precipitating high-energy electrons both at low and high altitudes and with other Antarctic Upper Atmospheric research efforts, such as the Automatic Geophysical Observatory programs and routine upper atmospheric observations at manned bases.

The project will specifically test if the oxygen isotopes 16O, 17O, 18O of nitrate can be used to probe the denitrification of the Antarctic stratosphere. Despite decades of research, there are several important issues in Antarctic atmospheric science, which are presently inadequately resolved. This includes quantification over time of the sources of nitrate aerosols. Today, little is known about the past denitrification of the stratosphere in high latitude regions. This lack of knowledge significantly limits our ability to understand the chemical state of ancient atmospheres and therefore evaluate present and past-coupled climate/atmosphere models. The role of nitrogen in environmental degradation is well known. This issue will also be addressed in this proposal. Atmospheric aerosols have now been shown to possess a mass-independent oxygen isotopic content. The proposed research will investigate the stable oxygen isotope ratios of nitrate in Antarctica both collected in real time and from the snow. Two periods of time will be covered. Full year nitrate aerosol collections, with week resolution time horizons, will be performed at the South Pole. Weekly aerosol collections will help us to identify any seasonal trend of the oxygen-17 excess anomaly, and eventually link this anomaly to the denitrification of the Antarctic stratosphere. This data set will also be used to test our assumption that the oxygen isotopic anomaly of nitrate is mainly formed in the stratosphere and is well preserved in the snow pack.

Following successful design and deployment of the collector, recovered particles will be catalogued and distributed to interested researchers. ***", "east": null, "geometry": null, "instruments": "IN SITU/LABORATORY INSTRUMENTS \u003e PROBES \u003e ELECTRON MICROPROBES; IN SITU/LABORATORY INSTRUMENTS \u003e PHOTON/OPTICAL DETECTORS \u003e SCANNING ELECTRON MICROSCOPES; IN SITU/LABORATORY INSTRUMENTS \u003e SAMPLERS \u003e GRABBERS/TRAPS/COLLECTORS \u003e SEDIMENT TRAPS", "is_usap_dc": true, "keywords": "USAP-DC; Micrometeorites; SEM/EMAX; GROUND-BASED OBSERVATIONS; South Pole Water Well; Glass Spherules", "locations": "South Pole Water Well", "north": null, "nsf_funding_programs": "Antarctic Glaciology", "paleo_time": null, "persons": "Taylor, Susan", "platforms": "LAND-BASED PLATFORMS \u003e PERMANENT LAND SITES \u003e GROUND-BASED OBSERVATIONS", "repo": "USAP-DC", "repositories": "USAP-DC", "science_programs": null, "south": null, "title": "Retrieval and Analysis of Extraterrestrial Particles from the Water Well at the South Pole Station, Antarctica", "uid": "p0000057", "west": null}]
