The 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. Version Description: The RAGES component of WISSARD concentrates on the stability of ice stream grounding zones (GZ), the area where the ice, ocean waters and glacial and sea floor sediment interact. Based on our present limited data and modeling efforts, GZs can be perturbed by (i) internal ice stream dynamics, (ii) filling/draining cycles of subglacial lakes, (iii) increased melting by warming ocean waters, and/or (iv) rates of subglacial sediment (till) supply to the GZ. GZs are seen as high priority targets to investigate due to their unknown contributions to ice sheet stability under future global warming scenarios. The three main science goals for RAGES are to assess: (a) West Antarctic Ice Sheet (WAIS) stability relative to the magnitudes of the four main variables listed above; (b) the degree to which grounding-zone sedimentary systems house important records of past WAIS dynamics; and (c) the importance of microbial activity and subglacial geochemical weathering in supplying nutrients to the WAIS grounding zone, the Ross Ice Shelf (RIS) cavity, and the highly productive Southern Ocean that may ultimately influence global biogeochemical cycles.IRIS > Incorporated Research Institutions for Seismologyhttp://www.iris.edu/httpcustodianIRIS > Incorporated Research Institutions for Seismologyhttp://www.iris.edu/httpdistributorNSIDC > National Snow and Ice Data Centerhttp://nsidc.orghttpcustodianNSIDC > National Snow and Ice Data Centerhttp://nsidc.orghttpdistributorSRIDHAR ANANDAKRISHNANIRIS > Incorporated Research Institutions for SeismologyPennsylvania State UniversityDept of Geosciences442 Deike BldgUniversity ParkPA16802USsxa17@psu.edusak@essc.psu.edupointOfContactNSIDC USER SERVICESNSIDC > National Snow and Ice Data Center+1 (303) 492-6199+1 (303) 492-2468National Snow and Ice Data CenterCIRES, 449 UCBUniversity of ColoradoBoulderCO80309-0449USAnsidc@nsidc.orgpointOfContactSRIDHAR ANANDAKRISHNANPennsylvania State UniversityDept of Geosciences442 Deike BldgUniversity ParkPA16802USsxa17@psu.edusak@essc.psu.edupointOfContactNSF/PLR > Division of Polar Programs, National Science FoundationprojectEARTH SCIENCE > CRYOSPHERE > GLACIERS/ICE SHEETS > NONE > NONE > NONE > NONEEARTH SCIENCE > CRYOSPHERE > SNOW/ICE > NONE > NONE > NONE > NONEthemeGCMDGEOGRAPHIC REGION > POLAR > NONE > NONE > NONE > NONECONTINENT > ANTARCTICA > NONE > NONE > NONE > NONEplaceAntarcticsub-glacialsub-ice-shelfbasal icestabilitysea floor sedimentgrounding linegeochemistrybiogeochemicalNot providedFIELD INVESTIGATIONFIELD SURVEYSLABORATORYplatformCORING DEVICESinstrumenthttp://www.wissard.org/wissard-science/science-projects/ragesDescription:
