GRANTS

2016-2019: Collaborative Research: Stability and Dynamics of Antarctic Marine Outlet Glaciers, NSF, Award No. (FAIN): ANT-1543530, $440,000, Paden is Co-Investigator.

The objective of this research is to gain a better understanding of glacier ice flow in the transition region from grounded ice to floating ice shelves. The research targets three glaciers in the West Antarctic and will investigate whether ongoing changes in these glaciers will lead to long-term mass loss or whether these glaciers will stabilize. The CReSIS contribution to the proposal is to generate fine resolution bed topographic maps to capture smaller-scale bed features that may control the flow of these glaciers and to support radar image analysis to recover additional geophysical parameters of the bed interface.

2015-2019: Airborne Radar Surveys of Land and Sea Ice and Data Processing Using CReSIS Instrumentation to Support IceBridge Observations, NASA Award: FED0074770/ NNX16AH54G, $6,111,162, Paden is Co-Investigator.

2013-2017 NASA Adaptation of the Snow Radar for NASA Global Hawk and Ikhana Unmanned Aircraft in Support of Operation Ice Bridge with internal match of $30K from KUCR and CReSIS, NASA, $490,000, Award Number: FED0071958, Federal Award Number: NNX13AQ30A, Principle Investigator.

2015-2016 Multi-agent Airborne Laboratory for Cryospheric Remote Sensing, Paul G Allen Family Foundation, $199,356, Paden is Co-Investigator.

2014-2015 Airborne Ultrawide Radars for Sounding and Imaging of Ice Sheets And Fine resolution Mapping of Internal Layers, Alfred Wegener Institute for Polar and Marine Research, $2,643,500, Paden is Co-Investigator.

2014-2019 NSF CIF21 DIBBs: High Performance Scalable Interoperable Data Analytics Libraries: Abstractions, Communities, Exemplars (SPIDAL project), Principal Investigator: Geoffrey Fox at Indiana University, $256,569 + $7,452 + $8,430 (subaward + 2015 REU supplement + 2016 REU supplement), Project Number: UNI0070344 + UNI0075021, Federal Award Number: ACI-1443054, Subaward Number: BL-4848800- UK, Paden is Subaward Principle Investigator.

The goal for the SPIDAL project is to create software abstractions to help connect communities together with applications in different scientific fields, letting us collaborate and use other communities’ tools without having to understand all of their details. The project will integrate features of traditional high-performance computing, such as scientific libraries, communication and resource management middleware, with the rich set of capabilities found in the commercial Big Data ecosystem. The latter includes many important software systems, such as Hadoop, available from the Apache open source community. CReSIS contribution to SPIDAL is to use HPC computing to solve large global optimization problems related to internal layer tracking and generation of ice bed digital elevation models from 3-D images generated from the petabyte-scale CReSIS radar dataset.

2012-2016 NSF MRI: Development of a high-power, large antenna array and ultrawideband radar for a Basler for sounding and imaging of fast-flowing glaciers and mapping internal layers, Principal Investigator: Richard Hale, $2,546,171, Federal Award Number: ANT-1129716, Paden is Co-Investigator.

Intellectual Merit: The development of an ultra-wideband (150-600 MHz) radar with a large cross-track array of 24 elements for basal and englacial imaging of ice sheets and glaciers. Broader Impacts: The application of the developed technology to other geophysical studies, including sea ice, permafrost, soil moisture, vegetation, and snow thickness over land. Resulted in 3 peer-reviewed presentations and 1 peer reviewed articles (Wang 2015) with several other articles. One MS thesis completed.
