An ice shelf begins where the land ice goes afloat on the ocean, and as such, the Ross Ice Shelf interacts with the ocean and seafloor below, and the land ice behind. Currently, the Ross Ice Shelf slows down, or buttresses, the fast flowing ice streams of the West Antarctic Ice Sheet (WAIS), a marine-based ice sheet, which if melted, would raise global sea level by 3-4 meters. The Ross Ice Shelf average ice thickness is approximately 350 meters, and it covers approximately 487,000 square kilometers, an area slightly larger than the state of California. The Ross Ice Shelf has disappeared during prior interglacial periods, suggesting in the future it may disappear again. Understanding the dynamics, stability and future of the West Antarctic Ice Sheet therefore requires in-depth knowledge of the Ross Ice Shelf. The ROSETTA-ICE project brings together scientists from 4 US institutions and from the Institute of Geological and Nuclear Sciences Limited, known as GNS Science, New Zealand. The ROSETTA-ICE data on the ice shelf, the water beneath the ice shelf, and the underlying rocks, will allow better predictions of how the Ross Ice Shelf will respond to changing climate, and therefore how the WAIS will behave in the future. The interdisciplinary ROSETTA-ICE team will train undergraduate and high school students in cutting edge research techniques, and will also work to educate the public via a series of vignettes integrating ROSETTA-ICE science with the scientific and human history of Antarctic research. The ROSETTA-ICE survey will acquire gravity and magnetics data to determine the water depth beneath the ice shelf. Radar, LIDAR and imagery systems will be used to map the Ross Ice Shelf thickness and fine structure, crevasses, channels, debris, surface accumulation and distribution of marine ice. The high resolution aerogeophysical data over the Ross Ice Shelf region in Antarctica will be acquired using the IcePod sensor suite mounted externally on an LC-130 aircraft operating from McMurdo Station, Antarctica. Field activities will include ~36 flights on LC-130 aircraft over two field seasons in Antarctica. The IcePod instrument suite leverages the unique experience of the New York Air National Guard operating in Antarctica for NSF scientific research as well as infrastructure and logistics. The project will answer questions about the stability of the Ross Ice Shelf in future climate, and the geotectonic evolution of the Ross Ice Shelf Region, a key component of the West Antarctic Rift system. The comprehensive benchmark data sets acquired will enable broad, interdisciplinary analyses and modeling, which will also be performed as part of the project. ROSETTA-ICE will illuminate Ross ice sheet-ice shelf-ocean dynamics as the system nears a critical juncture but still is intact. Through interacting with an online data visualization tool, and comparing the ROSETTA-ICE data and results from earlier studies, we will engage students and young investigators, equipping them with new capabilities for the study of critical earth systems that influence global climate.", "east": 161.0, "geometry": "POINT(-174.5 -81.5)", "instruments": "EARTH REMOTE SENSING INSTRUMENTS \u003e ACTIVE REMOTE SENSING \u003e PROFILERS/SOUNDERS \u003e RADAR SOUNDERS \u003e RADAR ECHO SOUNDERS; IN SITU/LABORATORY INSTRUMENTS \u003e MAGNETIC/MOTION SENSORS \u003e GRAVIMETERS \u003e GRAVIMETERS; EARTH REMOTE SENSING INSTRUMENTS \u003e ACTIVE REMOTE SENSING \u003e PROFILERS/SOUNDERS \u003e LIDAR/LASER SOUNDERS \u003e LIDAR; EARTH REMOTE SENSING INSTRUMENTS \u003e PASSIVE REMOTE SENSING \u003e MAGNETIC FIELD/ELECTRIC FIELD INSTRUMENTS \u003e PROTON MAGNETOMETER", "is_usap_dc": true, "keywords": "Airborne Radar; LIDAR; Ross Ice Shelf; SALINITY; SALINITY/DENSITY; CONDUCTIVITY; ICE DEPTH/THICKNESS; Tidal Models; GRAVITY ANOMALIES; Ross Sea; Antarctica; BATHYMETRY; C-130; MAGNETIC ANOMALIES; USAP-DC; Airborne Gravity", "locations": "Ross Sea; Antarctica; Ross Ice Shelf", "north": -77.0, "nsf_funding_programs": "Antarctic Ocean and Atmospheric Sciences; Antarctic Glaciology; Antarctic Integrated System Science; Antarctic Integrated System Science", "paleo_time": null, "persons": "Bell, Robin; Frearson, Nicholas; Das, Indrani; Fricker, Helen; Padman, Laurence; Springer, Scott; Siddoway, Christine; Tinto, Kirsty", "platforms": "AIR-BASED PLATFORMS \u003e PROPELLER \u003e C-130", "repo": "USAP-DC", "repositories": "PI website; USAP-DC", "science_programs": null, "south": -86.0, "title": "Collaborative Research: Uncovering the Ross Ocean and Ice Shelf Environment and Tectonic setting Through Aerogeophysical Surveys and Modeling (ROSETTA-ICE)", "uid": "p0010035", "west": -150.0}, {"awards": "1245749 Levy, Joseph; 1246203 Gooseff, Michael; 1246342 Fountain, Andrew", "bounds_geometry": "POLYGON((160.105465 -77.2119,160.7907435 -77.2119,161.476022 -77.2119,162.1613005 -77.2119,162.846579 -77.2119,163.5318575 -77.2119,164.217136 -77.2119,164.9024145 -77.2119,165.587693 -77.2119,166.2729715 -77.2119,166.95825 -77.2119,166.95825 -77.3189628,166.95825 -77.4260256,166.95825 -77.5330884,166.95825 -77.6401512,166.95825 -77.747214,166.95825 -77.8542768,166.95825 -77.9613396,166.95825 -78.0684024,166.95825 -78.1754652,166.95825 -78.282528,166.2729715 -78.282528,165.587693 -78.282528,164.9024145 -78.282528,164.217136 -78.282528,163.5318575 -78.282528,162.846579 -78.282528,162.1613005 -78.282528,161.476022 -78.282528,160.7907435 -78.282528,160.105465 -78.282528,160.105465 -78.1754652,160.105465 -78.0684024,160.105465 -77.9613396,160.105465 -77.8542768,160.105465 -77.747214,160.105465 -77.6401512,160.105465 -77.5330884,160.105465 -77.4260256,160.105465 -77.3189628,160.105465 -77.2119))", "dataset_titles": "2014-2015 lidar survey of the McMurdo Dry Valleys, Antarctica; Active Layer Temperatures from Crescent Stream banks, Taylor Valley Antarctica", "datasets": [{"dataset_uid": "601075", "doi": "10.15784/601075", "keywords": "Antarctica; Dry Valleys; Glaciology; Paleoclimate; Permafrost; Soil Temperature; Taylor Valley", "people": "Gooseff, Michael N.", "repository": "USAP-DC", "science_program": null, "title": "Active Layer Temperatures from Crescent Stream banks, Taylor Valley Antarctica", "url": "https://www.usap-dc.org/view/dataset/601075"}, {"dataset_uid": "000209", "doi": "", "keywords": null, "people": null, "repository": "OpenTopo", "science_program": null, "title": "2014-2015 lidar survey of the McMurdo Dry Valleys, Antarctica", "url": "http://opentopo.sdsc.edu/datasetMetadata?otCollectionID=OT.112016.3294.1"}], "date_created": "Wed, 20 Dec 2017 00:00:00 GMT", "description": "Collaborative Research: THE MCMURDO DRY VALLEYS: A Landscape on the Threshold of Change is supported by the Antarctic Integrated System Science (AISS) program in the Antarctic Sciences Section of the Division of Polar Programs within the Geosciences Directorate of the National Sciences Foundation (NSF). The funds will support the collection of state-of-the-art high resolution LIDAR (combining the terms light and radar) imagery of the Dry Valleys of Antarctica in the 2014/2015 Antarctic field season, with LIDAR data collection and processing being provided by the NSF-supported NCALM (National Center for Airborne Laser Mapping) facility. LIDAR images collected in 2014/2015 will be compared to images from 2001 in order to detect decadal change. Additional fieldwork will look at the distribution of buried massive ice, and the impacts that major changes like slumping are having on the biota. All field data will be used to improve models on energy balance, and hydrology. Intellectual Merit: There have been dramatic changes over the past decade in the McMurdo Dry Valleys: glaciers are deflating by tens of meters, rivers are incising by more than three meters, and thermokarst slumps are appearing near several streams and lakes. These observations have all been made by researchers in the field, but none of the changes have been mapped on a valley-wide scale. This award will provide a new baseline map for the entire Dry Valley system, with high-resolution imagery provided for the valley floors, and lower resolution imagery available for the higher elevation areas that are undergoing less change. The project will test the idea that sediment-covered ice is associated with the most dramatic changes, due to differential impacts of the increased solar radiation on sediment-covered compared to clean ice, and despite the current trend of slightly cooling air temperatures within the Dry Valleys. Information collected on the topography, coupled with the GPR determined buried ice distributions, will also be incorporated into improved energy and hydrological models. In addition to providing the new high-resolution digital elevation model (DEM), the project will ultimately result in identification of areas that are susceptible to sediment-enhanced melt-driven change, providing a powerful prediction tool for the impacts of climate change. Broader Impacts: The new DEM will be immediately useful to a wide range of disciplines, and will provide a comprehensive new baseline against which future changes will be compared. The project will provide a tool for the whole community to use, and the investigators will work with the community to make them aware of the new assets via public presentations, and perhaps via a workshop. The map will have international interest, and will also serve as a tool for environmental managers to draw on as they consider conservation plans. Several undergraduate and graduate students will participate in the project, and one of the co-PIs is a new investigator. The imagery collected is expected to be of interest to the general public in addition to scientific researchers, and venues for outreach such as museum exhibits and the internet will be explored. The proposed work is synergistic with 1) the co-located McMurdo LTER program, and 2) the NCALM facility that is also funded by the Geosciences Directorate.", "east": 166.95825, "geometry": "POINT(163.5318575 -77.747214)", "instruments": "EARTH REMOTE SENSING INSTRUMENTS \u003e ACTIVE REMOTE SENSING \u003e ALTIMETERS \u003e LIDAR/LASER ALTIMETERS \u003e AIRBORNE LASER SCANNER", "is_usap_dc": true, "keywords": "USAP-DC; Antarctica; Not provided; LANDFORMS; NOT APPLICABLE", "locations": "Antarctica", "north": -77.2119, "nsf_funding_programs": "Antarctic Integrated System Science; Antarctic Integrated System Science; Antarctic Integrated System Science", "paleo_time": null, "persons": "Levy, Joseph; Gooseff, Michael N.; Fountain, Andrew", "platforms": "Not provided; OTHER \u003e NOT APPLICABLE \u003e NOT APPLICABLE", "repo": "USAP-DC", "repositories": "OpenTopo; USAP-DC", "science_programs": null, "south": -78.282528, "title": "Collaborative Research: THE MCMURDO DRY VALLEYS: A landscape on the Threshold of Change", "uid": "p0000076", "west": 160.105465}, {"awards": "0632292 Bell, Robin; 1240707 Fahnestock, Mark", "bounds_geometry": "POLYGON((65 -77.5,67.4 -77.5,69.8 -77.5,72.2 -77.5,74.6 -77.5,77 -77.5,79.4 -77.5,81.8 -77.5,84.2 -77.5,86.6 -77.5,89 -77.5,89 -78.25,89 -79,89 -79.75,89 -80.5,89 -81.25,89 -82,89 -82.75,89 -83.5,89 -84.25,89 -85,86.6 -85,84.2 -85,81.8 -85,79.4 -85,77 -85,74.6 -85,72.2 -85,69.8 -85,67.4 -85,65 -85,65 -84.25,65 -83.5,65 -82.75,65 -82,65 -81.25,65 -80.5,65 -79.75,65 -79,65 -78.25,65 -77.5))", "dataset_titles": "Data Access Tool; Processed Ice Penetrating Radar Altimeter data (SEGY format) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT; Processed Ice Penetrating Radar Data (jpeg images) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT ; Processed Ice Penetrating Radar Data (Matlab format) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT ; Processed Ice Penetrating Radar Data (Netcdf format) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT ", "datasets": [{"dataset_uid": "601285", "doi": null, "keywords": "Airborne Radar; Airplane; Antarctica; East Antarctica; Gamburtsev Mountains; Glaciers/ice Sheet; Glaciers/Ice Sheet; Glaciology; Ice Sheet; Radar Echo Sounder", "people": "Studinger, Michael S.; Bell, Robin", "repository": "USAP-DC", "science_program": null, "title": "Processed Ice Penetrating Radar Data (Netcdf format) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT ", "url": "https://www.usap-dc.org/view/dataset/601285"}, {"dataset_uid": "601284", "doi": null, "keywords": "Airborne Radar; Airplane; Antarctica; East Antarctica; Gamburtsev Mountains; Glaciers/ice Sheet; Glaciers/Ice Sheet; Glaciology; Ice Sheet; Radar; Radar Echo Sounder", "people": "Bell, Robin; Studinger, Michael S.", "repository": "USAP-DC", "science_program": null, "title": "Processed Ice Penetrating Radar Data (Matlab format) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT ", "url": "https://www.usap-dc.org/view/dataset/601284"}, {"dataset_uid": "001489", "doi": "", "keywords": null, "people": null, "repository": "MGDS", "science_program": null, "title": "Data Access Tool", "url": "http://www.marine-geo.org/tools/search/entry.php?id=AGAP_GAMBIT"}, {"dataset_uid": "601286", "doi": "10.15784/601286", "keywords": "AGAP; Airborne Radar; Airplane; Antarctica; East Antarctica; Gamburtsev Mountains; Glaciers/ice Sheet; Glaciers/Ice Sheet; Glaciology; Ice Sheet; Radar; Radar Echo Sounder", "people": "Studinger, Michael S.; Bell, Robin", "repository": "USAP-DC", "science_program": null, "title": "Processed Ice Penetrating Radar Data (jpeg images) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT ", "url": "https://www.usap-dc.org/view/dataset/601286"}, {"dataset_uid": "601283", "doi": "10.1594/IEDA/318208", "keywords": "Aerogeophysics; AGAP; Airborne Radar; Airplane; Antarctica; East Antarctica; Gamburtsev Mountains; Glaciers/ice Sheet; Glaciers/Ice Sheet; Glaciology; Ice Sheet; Radar; Radar Echo Sounder", "people": "Bell, Robin", "repository": "USAP-DC", "science_program": null, "title": "Processed Ice Penetrating Radar Altimeter data (SEGY format) from the Gamburtsev Mountains in Antarctica acquired during GAMBIT", "url": "https://www.usap-dc.org/view/dataset/601283"}], "date_created": "Sun, 29 Sep 2013 00:00:00 GMT", "description": "This award supports an aerogeophysical study of the Gamburtsev Subglacial Mountains (GSM), a Texas-sized mountain range buried beneath the ice sheets of East Antarctica.
