  1. Data Management at BNZ – LTER 2005 - 2006 A Look at Old Data Management Philosophies and Integrating New Data Management Ideas

  2. Outline • Year in Review • New Data Management Philosophy • The Upcoming Year

  3. The Past Year • New Personnel and Bibliography Search Engines • Migrated BCEF - BNZ Hourly Climate Records (1989 - Present: 2 million temperature records, 8 million soil records, 10 million other climate records (PAR, Vapor Pressure,….) • EML Compliance for 131 of our 132 Datasets • Full PDFs of Bibliographies

  4. Datafiles > Datasets > Study Study > Dataset > Datafiles Data Management and Server Philosophies Pros: Pros: • In Depth with Theory • Does not lose “Bigger Picture” • Searchable / Easy to Navigate • Easy to update • Raw data heavy Cons: Cons: • Hard to find Raw Data • Hard to update • Original project idea becomes lost

  5. Old Database Setup: Study > Dataset > Datafiles Study Search Level Dataset Dataset Datafile Datafile Datafile Datafile Datafile Datafile

  6. Tree Regeneration after fire: Yukon Lodgepole Pine Surveys Soil ph and weights Oganic layer depths Pre and Post Fire Seedling Counts and Diameter Tree age cores Population dynamics of black Spruce at it’s Northern Limit in the Brooks Range, AK Soil Ph Tree Density Ring-width Chronologies Recruitment of Spruce Current Example

  7. Old Dataset Search Architecture Personnel Biblography Dataset Title Site

  8. New Database Setup: Datafiles > Datasets > Study Datafile Datafile Datafile Datafile Datafile Datafile Dataset Dataset Search Level Study

  9. Tree regeneration after fire: Yukon Lodgepole Pine Survey, pre fire analysis Tree regeneration after fire: Yukon Lodgepole Pine Surveys, mineral soil analysis Tree regeneration after fire: Yukon Lodgepole Pine Surveys, organic soil analysis Tree regeneration after fire: Yukon Lodgepole Pine Surveys, seedlings analysis Tree regeneration after fire: Yukon Lodgepole Pine Surveys, tree age analysis Estimates of White Spruce density at two elevations from 1600-present Population dynamics across latitudes of black spruce at its northern limit in the Brooks Range, Alaska Recruitment of black and white spruce in the Brooks Range, Alaska Soil Ph at black spruce sites at its northern limit in the Brooks Range, Alaska Standardized ring-width chronologies for white and black spruce at three sites in the southern Brooks Range, Alaska Tree densities of black and white spruce in the Brooks Range, Alaska New Example

  10. New Datafile Search Architecture Personnel Category Biblography Datafile Keyword Site

  11. TRENDS: Dataset Contributions • Active Layer Depth • Seed Surveys • White Spruce Seedlings • Tree Band Data • Vegetation Percent Cover / Count

  12. The Coming Year in DM • Robust Climate/Soil Search Engine • New Cutting-Edge Server • Level 5 EML for all Datasets • Improved/Updated Metadata Form • Standardization: Vegetation Code / Climate Logging / Soil Measurements / GPS:GIS (UTM) / Active Layer Depth • Migrate CPCRW and FLS Climate Records into Relation DB • Generate Vegetation Database for Interior Alaska
