  3. IceBridge Background 2008: feasibility and cost analysis: “An analysis and summary of options for collecting ICESat-like data from aircraft” 2009: solicited proposals for instruments for Antarctic campaigns 2009 and Arctic campaigns 2011 ad hoc community-based steering committee responsible for flight planning 2010: ROSES call for instrument teams and IceBridge Science Team members IceBridge Science Team and instrument teams selected based on competitive proposalsshift from ad hoc steering committee to directed mission:level 1 science requirements and science justification 2011: ROSES call for IceBridge science 2012: ROSES call for next phase of IceBridge IceBridge is a directed mission. Project resources are available to meet level 1 science requirements and mission goals, rather than support for individual PI-led projects.

  12. IceBridge and the Research Community • IceBridge seeks the involvement of the broad research community to: • Use IceBridge data to measure and understand current changes in ice thickness • Incorporate IceBridge data into predictive models of changing ice cover • Use IceBridge data to improve and enhance the ICESat data set, the developing CryoSat-2 data set and the planned ICESat-2 data set • In addition, we seek community contributions that: • Vet the scientific accuracy and usability of IceBridge data and data products • Develop new techniques and algorithms necessary to address IceBridge Projected Science Requirements:http://bprc.osu.edu/rsl/IST/

  14. OIB Land Ice Phase 3-4 Strategy • Phase 1 (2008-2010): OIB demonstrated successful, spatially extensive data collections in both the Arctic and Antarctic • Phase 2 (2010-11): Rigorous science requirements adopted for planning and mission success analysis • Phase 3 (2012 – 2015) • Vet data for utility for solving science problems; • increase spatial and temporal coverage (UAVs); • Adopt advanced technologies (e.g. tomography); • develop an end-to-end vision that emphasizes rapid model/process output for resolution of key science questions • Phase 4 (2015-2020) • Acquire I-2 prelaunch data to assure quick continuity of dh/dt record • One post launch campaign in Arctic and Antarctic to assure continuity • Continued focused missions that • Utilize flexibility of airborne platforms • Combine in situ, airborne and spaceborne observation to increase confidence in interpretation • Maintain crucial instruments that are still unique to airborne platforms • Respond to unique, transient geophysical phenomena • http://bprc.osu.edu/rsl/IST/index_files/PROJECTDOCUMENTS.htm Tomographic image of Russel Glacier Courtesy of JPL, KU and OSU.
