He is currently developing a "green data center" at NSIDC with the goal of reducing the power consumption for cooling by 95%. Dave is the lead investigator on an NSF grant for project to design and prototype a process (through creation of "Data Rods") for addressing time-series data as pure objects that will enable time-centric change analysis of massive multi-modality cryospheric data. He is also the Project Manager on a project to build web services and analysis application for determining changes to the Greenland ice sheet. His latest project is to recover 1960s Nimbus satellite data to determine the sea ice extent during that decade.
