What's New for DOE Data Explorer

August 2013

Featured this month is the Comprehensive Epidemiologic Data Resource (CEDR), managed by the Oak Ridge Institute for Science and Education (ORISE) in Oak Ridge, Tennessee. CEDR holds health studies of DOE contract workers and environmental studies of areas surrounding DOE facilities. DOE recognizes the benefits of data sharing and supports the public's right to know about worker and community health risks. CEDR provides independent researchers and the public with access to de-identified data collected since the Department's early production years. Current CEDR holdings include more than 76 studies of over 1 million workers at 31 DOE sites. Access to these data is at no cost to the user. Most of CEDR's holdings are derived from epidemiologic studies of DOE workers at many large nuclear weapons plants, such as Hanford, Los Alamos, the Oak Ridge reservation, Savannah River Site, and Rocky Flats. These studies primarily use death certificate information to identify excess deaths and patterns of disease among workers to determine what factors contribute to the risk of developing cancer and other illnesses. In addition, many of these studies have radiation exposure measurements on individual workers. CEDR is supported by the Oak Ridge Institute for Science and Education (ORISE) in Oak Ridge, Tennessee. With about 1,500 Internet sites pointing to CEDR's web site, CEDR is a national user facility, with a large audience for data that are not available elsewhere.

The following collection citations were added to DDE during the month of August:

  • The Energy DataBus: NREL's Open-Source Application for Large-Scale Energy Data Collection and Analysis (OSTI ID 1084207)
  • Image Gallery of the U.S. Global Change Research Program (OSTI ID 1091087)
  • PACIFICA (PACIFic ocean Interior Carbon) Database: A Data Synthesis Resource (NDP-92), ORNL/CDIAC-159) (OSTI ID 1091305)
  • Stakeholder Database from the Center for Bioenergy Sustainability (Learn who the experts are) OSTI ID 1091337)

July 2013

The featured collection is the PHENIX plot database. Its specialized interface allows you to search for published data plots or those labeled "preliminary." PHENIX is a physics experiment taking data at the Relativistic Heavy Ion Collider (RHIC) facility at Brookhaven National Laboratory. It completed its 12th run in January 2013 as it investigates a new state of matter called the Quark-Gluon Plasma. In addition to the plot database, figures and data plots are also available at http://www.phenix.bnl.gov/WWW/talk/pub_papers.php. Be sure to explore the home page of the Pioneering High Energy Nuclear Interaction eXperiment (PHENIX) to see images from past events and learn more about the science of PHENIX.

The following citations were added to DDE during the month of July:

  • The DOE Digital Photo Archive (OSTI ID 1087666)
  • International H2O Project (IHOP) 2002: Data sets Related to Atmospheric Moisture and Rainfall Prediction (OSTI ID 1087653)
  • NRELOpenStudio Tutorial Videos on YouTube (OSTI ID 1084204)
  • SmartGrid: Quarterly Data Summaries from the Data Hub and SmartGrid Project Information from OpenEI and SmartGrid.gov. (OSTI ID 1088044)

June 2013

The featured collection for June comes from the Center for Computational Sciences and Engineering (CCSE), located at the Lawrence Berkeley National Laboratory (LBL), California. The Center is funded by DOE's Office of Science and headed by Dr. John Bell. CCSE focuses on the development and application of computer simulations for complex fluid flow problems. The overview of their research, posted on the CCSE website notes: "The diverse range of scientific applications that drive our research typically involve a large range of spatial and temporal scales (e.g. turbulent reacting flows) and require the use of extremely large computing hardware, such as the 153,000-core computer, Hopper, at NERSC. Our approach to these problems centers on the development and application of advanced algorithms that exploit known separations in scale; for many of our application areas this results in algorithms are several orders of magnitude more efficient than traditional simulation approaches."

Select one of the simulations they have made available for public access on the CCSE home page. You will be taken to a full page of information that puts the research and its results into context. Links into the various projects associated with each simulation lead to even more detail, images, links to references, etc.

May 2013

May 1, 2013 marks the launch of a new look and feel for the DOE Data Explorer website ... and that's not all. The database itself has been redesigned with new, underlying software, new functionalities, and more content. Here's a quick summary of major changes:

  • Records identifying individual datasets/datastreams and submitted to OSTI from DOE Data Centers and other sites are now in the database along with DDE's original collection citations.
  • Boolean search is now available from the Advanced Search page.
  • More fields can be searched and a relevance sort is added.
  • Data range searching can be done for datasets with publication dates.
  • A breakdown by data types shows you how many items of each type were retrieved for each Search and each Browse operation.
  • Information about OSTI's Data ID Service is now part of the website.
  • The website shares the clean look and intuitive navigation of OSTI's new SciTech Connect. Learn to use one, and you already know how to use the other!
  • The new software will make it easier for OSTI to add future enhancements that some of our other products already have. An example is the capability to download searches into an Excel spreadsheet. Over the next year we will be looking at this and other improvements.

As always, we welcome your comments, your suggestions for future enhancements, and your questions. With so many new features rolling out at once, we certainly hope you will let us know if you encounter something that doesn't seem to be working correctly.
