  21. JCADM Report JCADM - 8Bremen, Germany

  22. Antarctic Master Directory • Redesigned AMD portal in 2003 • ISO compliant DIF • Portals added in support of National Antarctic Data Centers (NADCs) • Access to over 3000 DIFs • Consistently most popular portal with respect to DIF searches and retrievals JCADM - 8Bremen, Germany

  23. Antarctic Master DirectoryPortal Redesignhttp://gcmd.nasa.gov/Data/portals/amd/ • Design similar to GCMD with an Antarctic theme • Graphically enhanced with photographs • Topic keyword thumbnails are more relevant to Antarctic research • Customized top navigation bar including a link to JCADM website for more information • Added page listing National Antarctic Data Center (NADC) portals with links to each portal: http://gcmd.nasa.gov/Data/portals/amd/nadc_portals.html JCADM - 8Bremen, Germany

  32. Antarctic Master DirectoryContent Statistics – Growth 2002 to June 2004 JCADM - 8Bremen, Germany

  33. Antarctic Master DirectoryContent Statistics - Summary • Largest portion of DIF content is Biosphere (18%), followed by Cryosphere (14%), Oceans (14%), Land Surface (11%), Solid Earth (11%) and Atmosphere (11%) • Largest contribution of DIFs from Australian Antarctic Data Centre, followed by US Antarctic Data Centers/US Antarctic Data Coordination Center, and Centro de Datos Antárticos (Argentina) JCADM - 8Bremen, Germany

  38. Quarter 1 2004 Meiobenthic biodiversity and fluxes within the Antarctic biogeochemical environment (AMD/BE) Mass balance of the Antarctic ice cap (AMD/BE) An integrated approach to assess carbon dynamics in the Southern Ocean (AMD/BE) Ecofunctional biodiversity of benthic crustacean taxocoenoses in the Southern Ocean (AMD/BE) Aerogeophysical survey of western Marie Byrd Land, Antarctica (AMD/US) Marine Sediment Geochemistry Data (Pore Water) (CANADA/CGDI) Barium Biogeochemistry (AMD/BE) Response of the Southern Ocean global ecosystem to physical and trophic constraints (AMD/BE) Study of convective movements in the Southern Ocean (AMD/BE) Oceanography - Zooplankton Data for Antarctica from the Instituto Antartico Argentino (AMD/AR) Quarter 2 2004 AAD publications database (AMD/AU) Airborne Geophysical Data acquired by the NSF Support Office for Aerogeophysical Research (SOAR), University of Texas Institute for Geophysics, 1994-2000. (AMD/US) Meiobenthic biodiversity and fluxes within the Antarctic biogeochemical environment (AMD/BE) SOAR Airborne Geophysical Data Collected on the Pensacola/Pole Transect, Transantarctic (AMD/US) Mass balance of the Antarctic ice cap (AMD/BE) Antarctic Biodiversity Database (AMD/AU) 10 year trend of levels of organochlorine pollutants in Antarctic seabirds (AMD/AU) Marine Mammal Monitoring Data for Antarctica from the Instituto Antartico Argentino (AMD/AR) Seismic Experiment Ross Ice Shelf (AMD/US) Aerial Photography of Antarctica (AMD/US) Antarctic Master DirectoryUse Statistics – Retrievals: Top 10 DIFs 2004 JCADM - 8Bremen, Germany

  39. Antarctic Master DirectoryUse Statistics - Summary • Searches in 2004 show a slight increase over the last six months of 2003 • Based on number of hits per topic, the most popular topics are: Cryosphere, followed by Oceans, Atmosphere, Biosphere, Human Dimensions, and Solid Earth, respectively. • Overall, number of retrievals increasing • Since November 2003, AMD accounts for approximately 9% of all portal searches • AMD is the most popular portal of 35 portals JCADM - 8Bremen, Germany

  40. Antarctic Master DirectoryUse Statistics – Top 10 DIFs Discussed • First Quarter 2004: DIFs from IDN Node AMD/BE (Belgium) were retrieved more often than any other DIFs • Second Quarter 2004: Only 2 DIFs from IDN Node AMD/BE appeared in the Top 10 list • Possible Explanations: • Users are looking at the DIFs as examples of metadata for new NADCs • The DIFs are keyed with popular keywords having to do with ecology/biology and ice cap mass balance, which are closely linked to global climate change JCADM - 8Bremen, Germany

  41. Antarctic Master DirectoryUse Statistics – Top 10 DIFs Discussed Increasing retrievals of DIFs: • Key DIFs with as many pertinent controlled and free-text keywords as possible • Write comprehensive summaries • Note: Free-text search engine, Isite, does ranking on term frequency and where the term appears in the document. • Keep DIFs up to date JCADM - 8Bremen, Germany

  42. Antarctic Master DirectoryFuture • Newly designed keyword interface with left-hand side navigation and link to Data Services (preview: http://gcmd.sesda.com:1881/KeywordSearch/Home.do?Portal=amd&MetadataType=0) • Link to Data Services • Do-It-Yourself portals • New geospatial search capability packaged with Lucene free-text search • Stand-alone version of docBUILDER for use in the field JCADM - 8Bremen, Germany

  43. Antarctic Master DirectoryFuture – New Keyword Interface Preview JCADM - 8Bremen, Germany

  44. Antarctic Master DirectoryChallenges • Encouraging updates from NADC’s and researchers • Restrictions on working with certain countries, which puts limits on the international aspects of the AMD • Acquiring and implementing a map in polar projection for a more thorough spatial search • Suggestions on enhancing AMD visibility with search engines such as Google JCADM - 8Bremen, Germany
