The LISSARD project (Lake and Ice Stream Subglacial Access Research Drilling) is one of three research components of the WISSARD integrative initiative (Whillans Ice Stream Subglacial Access Research Drilling) that is being funded by the Antarctic Integrated System Science Program of NSF's Office of Polar Programs, Antarctic Division.UnknownIt is unknown if this record has a DOI.2017-04-21T00:00:00.000ZThe overarching scientific objective of WISSARD is to assess the role of water beneath a West Antarctic ice stream in interlinked glaciological, geological, microbiological, geochemical, and oceanographic systems. The LISSARD component of WISSARD focuses on the role of active subglacial lakes in determining how fast the West Antarctic ice sheet loses mass to the global ocean and influences global sea level changes. The importance of Antarctic subglacial lakes has only been recently recognized, and the lakes have been identified as high priority targets for scientific investigations because of their unknown contributions to ice sheet stability under future global warming scenarios. LISSARD has several primary science goals: A) To provide an observational basis for improving treatments of subglacial hydrological and mechanical processes in models of ice sheet mass balance and stability; B) To reconstruct the past history of ice stream stability by analyzing archives of past basal water and ice flow variability contained in subglacial sediments, porewater, lake water, and basal accreted ice; C) To provide background understanding of subglacial lake environments to benefit RAGES and GBASE (the other two components of the WISSARD project); and D) To synthesize data and concepts developed as part of this project to determine whether subglacial lakes play an important role in (de)stabilizing Antarctic ice sheets. We propose an unprecedented synthesis of approaches to studying ice sheet processes, including: (1) satellite remote sensing, (2) surface geophysics, (3) borehole observations and measurements and, (4) basal and subglacial sampling.Not providedIRISsearch for wissard seismicACTIVEPOLARANTARCTICAfalse2009-09-01T00:00:00.000Z2014-08-31T23:59:59.999ZARCHIVERIRISSRIDHARANANDAKRISHNANDATA CENTER CONTACTDISTRIBUTORIRISSRIDHARANANDAKRISHNANDATA CENTER CONTACTARCHIVERNSIDCNSIDCUSER SERVICESDATA CENTER CONTACTDISTRIBUTORNSIDCNSIDCUSER SERVICESDATA CENTER CONTACTTECHNICAL CONTACTSRIDHARANANDAKRISHNANINVESTIGATOREARTH SCIENCECRYOSPHEREGLACIERS/ICE SHEETSEARTH SCIENCECRYOSPHERESNOW/ICENot providedNot providedNot providedSEISMOGRAPHSSeismometersFIELD INVESTIGATIONNot providedNot providedFIELD SURVEYSNot providedNot providedLABORATORYNot providedNot providedSATELLITESNot providedNot providedmetadata.uuidSTRINGNot provided8dc55bfe-4be8-4e76-85c0-bf11782f6168metadata.extraction_dateSTRINGNot provided2015-12-02 14:16:04metadata.keyword_versionFLOATNot provided8.1NSF/PLRDivision of Polar Programs, National Science FoundationHORIZONTALhttp://www.iris.edu/hq/data_and_software
IRIS offers free and open access to a comprehensive data store of raw geophysical time-series data collected from a large variety of sensors, courtesy of a vast array of US and International scientific networks, including seismometers (permanent and temporary), tilt and strain meters, infrasound, temperature, atmospheric pressure and gravimeters, to support basic research aimed at imaging the Earth's interior.
