The proposed operations plan includes five years of survey observations to obtain ultra-deep measurements of a 1500 square degree field with SPT-3G, as well as the production and public archiving of essential data products from the survey. The data products from SPT-3G as well as the previous SPTpol survey will be released to the public at regular and timely intervals over the project period. The operations also support SPT\u2019s 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 our Galaxy.\r\n\r\nThe SPT-3G instrument, first deployed in the 2016-17 Austral summer, is a major upgrade in capabilities over previous generations of SPT cameras, with over 16,000 detectors configured for polarization-sensitive observations in three frequency bands. The SPT-3G maps of the temperature, polarization, and lensing potential of the CMB will have an unprecedented combination of depth, resolution and sky coverage (1500 square degrees). This unique data set will enable broad and impactful science, from sensitive constraints on inflationary models to the formation and evolution of galaxies.\r\n\r\nWorking in collaboration with the BICEP/Keck team, we will use the high-resolution SPT-3G data to remove the gravitational lensing signal from BICEP Array maps to enable a deep search for primordial gravitational waves (PGW). The full SPT-3G data set funded by this proposal will allow delensing of BICEP Array data that could improve constraints on PGW by more than a factor of two. \r\nThe SPT-3G temperature and polarization power spectrum measurements 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 standard cosmological model (LCDM). One of the most well-motivated extensions to LCDM in light of these tensions is the existence of new light particles in the early Universe: SPT-3G will improve sensitivity to such particles by at least a factor of two over current CMB experiments.\r\n\r\nSPT-3G data will be used to constrain the properties of dark energy from its effect on the growth of structure through both CMB lensing and the abundance of galaxy clusters. These two observables will also be used to place nearly independent constraints on the sum of the neutrino masses. The unique catalogs of high-redshift galaxy clusters and early star-forming galaxies produced by SPT-3G will be used to understand cluster formation and trace massive galaxy evolution from the epoch of reionization to the peak of star formation.\r\n\r\nPublic data products will include temperature and polarization maps in all three SPT-3G frequency bands, CMB angular power spectra, gravitational lensing maps and power spectra, a catalog of distant massive galaxy clusters, and catalogs of mm-wave-bright galaxies.\r\n\r\nThis project is designed to provide calibrated, uniform, and publicly archived data products that will enable scientific breakthroughs in multiple areas. The public SPT data products will impact the larger community by enabling a broad range of studies that address some of the most compelling questions in cosmology and astrophysics. The sharing of the spirit of scientific inquiry will be extended beyond the research community through a well-established education network at all levels of the education continuum, from early childhood through graduate school. Summer Schools on CMB Instrumentation will be taught by the Co-I\u2019s and senior personnel on this proposal. For our proposed First Discoveries program, we will partner with The University of Chicago\u2019s Neighborhood Schools Program to work with students and teachers in less-advantaged classrooms to foster scientific reasoning through inquiry-based learning.", "east": 0.0, "geometry": "POINT(0 -90)", "instruments": "SOLAR/SPACE OBSERVING INSTRUMENTS \u003e RADIO WAVE DETECTORS \u003e RADIO TELESCOPES", "is_usap_dc": true, "keywords": "USAP-DC; AMD; Adelie Penguin; THERMAL INFRARED; South Pole Station; Amd/Us; OBSERVATORIES", "locations": "South Pole Station", "north": -90.0, "nsf_funding_programs": "Antarctic Science and Technology; Polar Special Initiatives; Antarctic Astrophysics and Geospace Sciences", "paleo_time": null, "persons": "Carlstrom, John; Holzapfel, William; Benson, Bradford", "platforms": "LAND-BASED PLATFORMS \u003e PERMANENT LAND SITES \u003e OBSERVATORIES", "repositories": null, "science_programs": null, "south": -90.0, "title": "South Pole Telescope Operations and Data Products", "uid": "p0010176", "west": 0.0}, {"awards": "1638957 Kovac, John", "bounds_geometry": "POINT(0 -90)", "dataset_titles": "BICEP/Keck data products", "datasets": [{"dataset_uid": "200205", "doi": "", "keywords": null, "people": null, "repository": "Project website", "science_program": null, "title": "BICEP/Keck data products", "url": "http://bicepkeck.org"}], "date_created": "Wed, 31 Mar 2021 00:00:00 GMT", "description": "The theory of the \"Big Bang\" provides a well-established cosmological model for the Universe from its earliest known periods through its subsequent large-scale evolution. 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.\u003cbr/\u003e \u003cbr/\u003eThe 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.

The intellectual merits of this project are as follows: 1) to constrain and improve the parameterization of firn thermal properties (thermal conductivity and specific heat capacity) that are required for the borehole paleothermometry, 2) to study the change in firn temperature since the deployment of thermal profiling units ~5 years ago and derive the surface temperature trend for that time period, and 3) to compare and contrast the surface temperatures and their trends derived from the measured firn temperatures and satellite thermal infrared data for the past three decades. The project also involves acquiring and deploying an automated system to record transient temperatures at multiple depths in the top 16 meters of the shallow borehole at Dome Fuji, to provide useful data and to prepare for the possibility of conducting temperature-logging in the existing deep (3035 m) and shallow (112 m) boreholes at Dome Fuji in the near future. The preparation of the shallow borehole and the installation of the automated system will be carried out by collaborators from the Japanese Antarctic Research Expedition (JARE) in 2012-13 Antarctic field season. The data collected by this automated system will be used to constrain the thermal properties of upper firn layer at Dome Fuji, as well as comparing with data from other sites, increasing the geographic extent of these studies.

Erebus is one of only a handful of volcanoes worldwide that have lava lakes with readily observable and nearly continuous Strombolian explosive activity. Erebus is also unique in having a permanent convecting lava lake of anorthoclase phonolite magma. Over the years significant infrastructure has been established at the summit of Mt. Erebus as part of the Mount Erebus Volcano Observatory (MEVO), which serves as a natural laboratory to study a wide range of volcanic processes, especially magma degassing associated with an open convecting magma conduit. The PI proposes to continue operating MEVO for a further five years. The fundamental fundamental research objectives are: to understand diffuse flank degassing by using distributed temperature sensing and gas measurements in ice caves, to understand conduit processes, and to examine the environmental impact of volcanic emissions from Erebus on atmospheric and cryospheric environments. To examine conduit processes the PI will make simultaneous observations with video records, thermal imaging, measurements of gas emission rates and gas compositions, seismic, and infrasound data.\u003cbr/\u003e\u003cbr/\u003eBroader impacts: \u003cbr/\u003eAn important aspect of Erebus research is the education and training of students.
